You don't become a leader in an industry with only a casual interest in your business. If you want to be number one in tires, you think, eat and sleep tires, 365 days a year. As a result of this dedication, Goodyear continues to roll out the tires America wants.
Testing Standards
Goodyear works hard to put the best possible tires on the road. Our testing standards exceed those of the government, to ensure that every product we make delivers high quality performance and dependability. See for yourself how Goodyear products live up to the highest of expectations.
In the old days, we used to brag about the millions of test miles we racked up every year, citing "x" number of trips to the moon or around the equator. Today, we use predictive testing and a host of other methodologies to reduce field and lab test time. But that's only part of the story of Global Tire Performance Prediction (GTPP), one of the new disciplines created late last year in our realignment of RD&E.
Have We Raised Tire Manufacturing To An Art Form? Maybe.
But there's no denying the amount of influence Goodyear advances have had on the tire industry. Starting with the simple process of manufacturing a tire and refining it exponentially, we have repeatedly found ourselves on the cutting edge of tire technology. Learn more here about the creation of a tire and the heights to which Goodyear has raised the art.
Why Kelly Tires?
We've succeeded in the tire business for over 100 years because we know a lot about tires, and even more about the people who buy them. We understand that drivers like you are looking for a good deal on a great tire. High quality, long life, a warranty and reasonable price ? these are all important features. It's the kind of tire deal you can expect to find through the network of Kelly Tires Dealers.

Welcome to Dunlop. Where the smell of hot rubber and the crunch of asphalt beneath beefy wheels are two of life's finest experiences. Dunlop is about driving. Driving is about Dunlop. And it's been this way since our beginning.
It all started in 1888, when a small boy struggled to ride a tricycle with solid rubber wheels. John Boyd Dunlop grew tired of watching his son struggle with the cumbersome tires and patented his own design - marking the birth of what we now know as today's modern-day tire.
The legend grew by leaps and bounds - and RPMs. What started as a tricycle tire grew to become a racing radial for 200 mph motorsport vehicles, way ahead of the times. The Dunlop name became as popular in racing circles as that notorious checkered flag.
So here we are today, thriving on that motorsports heritage. Blending the latest technology with OE experience. Taking everything we learn on the race tracks and incorporating it into tires for the most discerning drivers.
That's Dunlop. And that's driving.
Bridgestone Americas' corporate family (BSA) traces its roots to the establishment of The Firestone Tire & Rubber Company in August 1900. It was then that 31-year-old Harvey S. Firestone (1868-1938) started tire production with 12 employees in Akron, Ohio.
On the other side of the globe in 1931, Shojiro Ishibashi (1885-1976) created Bridgestone Tire Company Ltd. (later renamed Bridgestone Corporation). He fashioned the company name by reversing the English translation of his own: "Ishibashi," which literally means "stone bridge" in Japanese.
Bridgestone Corporation purchased Firestone in 1988 for $2.6 billion, transforming the companies' combined operations into the world's largest tire and rubber company. The operations in the Americas were renamed Bridgestone/Firestone, Inc. (BFS) and became the largest subsidiary of Bridgestone. As part of its integration with Bridgestone's existing U.S. operations, Bridgestone/Firestone moved its headquarters from Akron to Nashville in 1992.
In an effort to enhance its core business units and to address its customers' needs and wants, the company today does business in the Americas under a holding company structure in which Bridgestone Americas, Inc. (BSAM) owns several operating units and subsidiaries.
- Bridgestone Americas Tire Operations, LLC, the successor to BFS, is part of a larger business unit also known as Bridgestone Americas Tire Operations (BATO). Reporting into this business unit are the company's Latin American tire operations, the U.S. and Canadian consumer tire businesses and the U.S. and Canadian commercial tire businesses. These businesses include tire manufacturing and wholesale and original equipment sales operations across a broad line of products, including consumer, commercial truck and bus, agricultural, and off road tires. Product development and research related to these businesses are also conducted by BATO. BATO sells tires for passenger, light truck, truck, bus, off road, motorcycle, agricultural and kart applications through a variety of different outlets, including independent dealers, discount retailers, warehouse clubs and stores owned by Bridgestone Retail Operations, LLC (BSRO), a sister company to Bridgestone Americas Tire Operations, LLC. In addition, through its Bridgestone Bandag Tire Solutions (BBTS) unit, retreading customers have access to industry-leading research and development, manufacturing, marketing and sales expertise, providing them with a total tire solution.
- Bridgestone Retail Operations, LLC (BSRO), consists of a family of more than 2,000 company-owned vehicle service and tire locations across the United States, including Firestone Complete Auto Care?, Tires Plus?, ExpertTire? and Wheel Works? store locations. Credit First National Association and Firestone Complete Fleet Care? operations are also part of BSRO.
- Firestone Diversified Products, LLC (FSDP) consists of building and industrial products, natural rubber, and industrial fibers and textiles businesses.
- BSAM has international manufacturing and sales subsidiaries located in Argentina, Brazil, Chile, Colombia, Costa Rica, Mexico, and Venezuela, with additional sales representation throughout Latin America and the Caribbean.

BFGoodrich® brand tires are made and sold to owners of cars, trucks, SUVs and vans.
A key appeal for driving a car, truck, SUV or van is the feeling that you can go anywhere. BFGoodrich® Tires Traction/Advantage goes that one better. Anytime. Anywhere.
BFGoodrich® Tires Traction/Advantage means that wherever you choose to go, and whatever the road decides to put in your path, you're in control.
In 1976, BFGoodrich® introduced the world's first performance light-truck radial, the Radial All-Terrain T/A®. To prove the durability and reliability of radials in off-road conditions, the engineers put the tire to the toughest test they could find: off-road racing. Since then, theBFGoodrich® brand has continued the tradition of racing the tires it sells to the public and using motorsports as a breeding ground for future technologies.
The Falken Tire brand, a subsidiary of Sumitomo Rubber Industries, launched in its native country of Japan in 1983 and was introduced to the North American market two years later. At its inception, Falken was created as the flagship high performance radial brand under Ohtsu Tire and Rubber. Now, over two and a half decades later, Falken continues to focus on UHP (Ultra High Performance) products and utilizing professional motorsports racing to further develop and improve passenger vehicle products for worldwide distribution.
Falken Tire Corporation, based in Fontana California, is the corporate headquarters and west coast distribution center for North American operations. Additional Falken Tire distribution locations include warehouses in Tennessee, New Jersey and Texas.
Falken's current products range from the track inspired and enthusiast targeted Azenis series to the maximum performance and luxury sport FK452. The award winning all-season performance Ziex ZE912 provides sure footed grip in any weather condition while the S/TZ04 encompasses cutting edge styling and ultra plus fitments for today's light truck and SUV's.
Future product development includes the expansion into rugged all-terrain, winter performance and premium touring categories.
Considered a marketing maverick in many regards, Falken Tire prides itself on its in house branding and creative capabilities. Housing a fully staffed advertising department and motorsports team allows Falken Tire to fully maximize exposure on internally operated American Le Mans and Professional Drifting programs.

Re-inventing the Wheel.
We at American Racing trace our roots back more than 50 years, and continue to reinvent ourselves and, quite literally, the wheel. Today's American Racing still prides ourselves on the mission that began when drag racing innovator Romeo Palamides teamed up with J.O. Ellison, a San Francisco machine shop owner, to design and craft high strength-to-weight ratio racing wheels for his dragster. Palamides and Ellison, along with engineering innovator Tom Griffith formed the pioneering company in aftermarket wheels. From the golden age of hot rodding to today's street enthusiast, American Racing is reinventing the way wheels are viewed from our classics to new trend-setting styles.
The Wheel that Started a Craze.
In the late 50s, when European racing wheel companies were focused on semi-solid modular designs, designer Tom Griffith conceived the tapered parabolic contour spoked American Racing "Torq Thrust®" which reduced wheel weight and promoted brake cooling. Considered by many to be the most famous wheel of all time, the Torq Thrust® started the custom wheel craze, making the conversion from strip to street. Today authentic "old school" Torq Thrusts are highly collectible and sold around the world. Often imitated, never duplicated, the Torq Thrust® is the signature wheel for performance and custom purists.
General Lee's Landing Gear.
During the seven seasons (147 episodes & 2 made-for-TV reunion movies) of the hit television series "Dukes of Hazzard", the Warner Brothers studio built a total of 340 "General Lee" 1969 Dodge Chargers. All "General Lees" were equipped with American Racing "Vector" wheels. Of the 340 General Lees built for the series, 321 were destroyed as a result of stunt car jumps. Of the 1360 American Racing Vectors jumped and stunt driven for the series, only one wheel failed by breaking and it is a collector item in a private collection in Sylmar, California. Beyond Hazzard County, American Racing wheels have had cameo appearances in some of Hollywood's most famous films including The Game, Die Hard With A Vengeance, Transformers, 2Fast 2Furious, and perhaps the most important Ford Mustang film of all time, Bullit.
Hot Rods.
What do you get when you combine the world's most respected wheel company with the world's most respected hot rod designer? In 2005, American Racing acquired Boyd Coddington specialty wheels combining two of the top names in wheel design. Coddington, a nationally-recognized auto enthusiast specializing in automotive restoration and customization, continues to work on wheel designs, sales efforts, marketing and events. In addition to his exploits in the automotive industry, Coddington became a national figure when the Discovery Channel launched the popular hit television show "American Hot Rod."
Trend Setters.
Twenty Inches Strong, TIS Modular and Dropstars wheels are at the forefront of design. In fact, they continually stretch the imagination of what is possible when it comes to turning a wheel into a rolling piece of art. American Racing and DUB co-founder Myles Kovacs continue the rich tradition of trend-setting designs and sizes through the TIS, TISm and Dropstars wheel lines, including the first production 30 inch wheel. Known for their 20-plus inch wheels, these unique wheels are popular among celebrities including today's hottest hip hop stars, top athletes and movie stars. If you have a ride and want to stand out, these wheels are a must have.
Who the Pros Come To.
When people who know cars want to put their name on a wheel, they come to us. Both Carroll Shelby and Dale Earnhardt Jr. wanted to give their fans a way to display their affection for these racing legends, but wanted to make sure that only the highest quality wheels would display their names. Through the Carroll Shelby® Legend Series and Dale Earnhardt Jr. Signature Series lines of wheels for cars, trucks, and SUV's, Ford and Chevy fans alike agree that legendary performance is attainable. However we do not recommend that you try to drive like either of them on your local highways.
The Leaders in Forged Technology.
When it was time to expand the manufacturing capabilities into forged designs, it was a natural to join forces with the industry leading brand with over 40 years of experience in forged wheel production. In acquiring the Weld Racing, we added one of the industry's best brands for forged motorcycle, motorsports and aftermarket wheels. Whether it is John Force on a drag strip, Tony Stewart on a dirt track, street strip or off road racers, Weld Racing wins. Along with the brand, we added state of the art forged manufacturing capabilities based in Kansas City, MO., where we continue to produce the best in one-piece and multi-piece forged wheels.
Not Just American Racing.
We have evolved with the changing landscape of the automotive market into a company with over a dozen brands, all developed with the purpose of providing high quality, cutting edge design wheels for the automotive aftermarket. From Hot Rods to Muscle Cars, Tuners to Trucks, Street Strip to Urban Cruising, on the road, off the road or on the track, American Racing Equipment, Inc. has a wheel that meets your needs under one of these industry leading brands: American Racing, American Racing Pro Series, ATX Series All Terrain Wheels, Boyd Coddington Wheels, Carroll Shelby® Legend Series, Dale Earnhardt Jr.® Signature Series, Dropstars, Imola, Motegi Racing, TIS ? Twenty Inches Strong, TISModular, and Weld Racing.
All In.
American Racing Equipment, Inc. is the largest wheel company in the world, distributing more than 1.5 million wheels annually through manufacturing facilities, company-owned, satellite-connected warehouses, an independent distributor system in the United States and through international distributors in more than 20 countries on four continents.
In Thrust We Trust. - American Racing®

Transmission Maintenance
Vehicles with automatic transmissions require transmission fluid. It protects the transmission from running too hot, especially during strenuous conditions such as towing or steep hills. If you will be putting more driving stress than normal on your vehicle, it's important to have your car inspected and serviced to prevent the transmission from overheating. However, completely flushing and replenishing your transmission fluid requires a specially-designed machine.
Emission Control: Emissions Testing Program
Description: A program designed to periodically check vehicle emissions to ensure they are within limits. Often referred to as an I/M (Inspection/Maintenance) program, they are used in numerous states and areas as required by the Environmental Protection Agency to improve air quality in those areas. Although the requirement comes from the federal government, states and their associated agencies have some flexibility in the type of test used, vehicle populations to be tested and other program-specific details. Some states run centralized programs that have state-contracted test stations exclusively dedicated to testing. Other states run decentralized programs, where emissions can be tested at local repair facilities. In a few cases, states may run "hybrid" programs using both centralized and decentralized test stations. The latest trend is to incorporate the use of second-generation onboard diagnostics (OBDII) into these programs, in many cases altogether eliminating the need for tailpipe emissions tests.
Purpose: I/M programs evaluate the emissions from vehicles and single out those that are polluting beyond the limits established for certain model years of vehicles. Aside from identifying vehicles with high emissions, such programs advocate proper maintenance to prevent high emissions due to maintenance neglect.
Maintenance Tips/Suggestions: The best way to keep your vehicle environmentally friendly is by performing regularly scheduled maintenance, rather than waiting to correct a problem after your car fails an emissions test. If the SERVICE ENGINE SOON or CHECK ENGINE light appears, have it checked out immediately by a professional technician. Neglecting these warning signs can cause lead to more extensive and expensive repairs.

Braking Systems
The brake system is actually composed of two kinds of systems---Hydraulics and Friction Materials. Here's what happens within these systems between the time your foot hits the brake pedal and your car stops.
Hydraulics
Master Cylinder
When pressure is applied to the brake pedal, the master cylinder creates hydraulic pressure which pushes brake fluid to the wheel brakes.
Brake Lines and Hoses
Steel brake lines and high pressure rubber hoses are the avenues through which the pressurized brake fluid travels.
Wheel Cylinders and Calipers
These are the hydraulic cylinders that apply pressure to the friction materials, causing your car to stop.
Friction Materials
Disc Brake Pads and Drum Brake Shoes
These brake linings are composed of high temperature materials that create the friction that stops your car.
Types of Brakes
Disc Brakes
Disc brakes consist of a Disc Brake Rotor, which is attached to the wheel, and a Caliper, which holds the Disc Brake Pads. Hydraulic pressure from the Master Cylinder causes the Caliper Piston to clamp the Disc Brake Rotor between the Disc Brake Pads. This creates friction between the pads and rotor, causing your car to slow down or stop.
Drum Brakes
Drum brakes consist of a Brake Drum attached to the wheel, a Wheel Cylinder, Brake Shoes and Brake Return Springs. Hydraulic pressure from the Master Cylinder causes the Wheel Cylinder to press the Brake Shoes against the Brake Drum. This creates friction between the shoes and drum to slow or stop your car.
Parking Brake
The Parking Brake uses Cables to mechanically apply the brakes (usually the rear brake.) This is used to prevent the car from rolling when not being driven.
Anti-Lock Brakes: A System Built For Safety
Computer-controlled anti-lock braking systems (ABS) are a recently developed safety feature. When sudden stops are made, the ABS prevents wheel lock-up. The system is comprised of wheel-speed sensors that monitor wheel rotation, computer-controlled hydraulics that pulse the brakes on and off rapidly, and the on-board computer.
Heating & Air Conditioning
Your car's engine is the power source for both heating and air conditioning systems. The systems also share other components, as the following diagram shows. Here's what happens when you flip on the heat or the air conditioner:
Heating System
Heat is a byproduct of the engine's combustion process. The heat is absorbed by the coolant in your car's radiator. The coolant is then circulated through the heater core before returning to the radiator. The heating system also includes a series of air ducts, a blower motor and fan, and temperature and duct controls, which selct the desired temperature and direct the flow of warm air.
Air Conditioning System
This system shares air ducts, controls and a blower with the heater, but has its own refrigerant system. The air conditioning system is comprised of the following components:Compressor
This is a pump that pressurizes and circulates the refrigerant through the system.
Condensor
As the refrigerant flows through the condensor, it gives up heat and converts from gas to liquid.
Receiver/Dryer or Accumulator
This is where clean, dry refrigerant is stored as it circulates through the system.
Orifice Tube or Expansion Valve
This is a metering device that controls the flow of refrigerant through the system.
Evaporator Core
Refrigerant enters the evaporator core as a liquid. Heat from the air converts the liquid refrigerant back into a gas, which cools the air before it enters you car.
Batteries
We can help you choose the right battery for your vehicle and lifestyle. Our staff can safely and professionally install your battery and get you back on the road.
Your car's electrical system powers everything from the ignition and fuel systems to accessories such as your radio, headlights and wipers. The electrical system is, in turn, powered by the engine. Here are the three key components of the electrical system:
When your car's engine is off, the battery provides the required power to the rest of the system, as well as during start-up (cranking). It also supplements the power from the charging system during periods of high demand.
Charging System
This is the heart of the electrical system. It consists of three main components: the belt-driven alternator, various electrical circuits, and a voltage regulator. The alternator supplies power to the electrical system and recharges the battery after your car has started. Just like it sounds, the voltage regulator controls the voltage, keeping it within the operating range of the electrical system.
Starting System
This system consumes more electrical power than any other in your car. The starting system consists of three components which work in tandem: the ignition switch, the starter relay or solenoid, and the starter motor. The ignition switch controls the starter solenoid, which activates the starter motor. The starter motor then turns the engine until your car starts.
Battery
Belts & Hoses
Exposure to heat, vibration and contamination makes belts and hoses wear out faster than any other components in your car. That's why regular inspections are so important. Here are the belt and hose types in your car, along with their applications.
Accessory Drive Belts
While some accessories in your car are electrically powered by the charging system, others use the engine itself as their power source. The power for these accessories is delivered by a system of pulleys and belts. Examples of these accessories are:
- Alternator
- Water Pump for engine cooling
- Power Steering Pump
- Air Conditioning Compressor
- Radiator Cooling Fan
- Many late model cars use a single serpentine belt in place of individual belts to drive these accessories.
Hoses
The hoses that convey your car's fluids are made of two rubber layers with a layer of fabric in between. Typical hoses include:
- Radiator and Heater Hoses - These hoses convey coolant to the engine and heater core.
- Fuel Hose - As the name implies, this hose transports gasoline from the tank to the engine.
- Power Steering Hose - It connects the power steering pump to the steering gear.
Cooling System Maintenance
What Our ASE Certified Technicians Do
The following components are inspected. Their condition is recorded and compared to manufacturer's specs. Recommendations are made per the Motorist Assurance Program Uniform Inspection Guidelines:
Heating and Air Conditioning Systems
Visual Inspection
- Interior controls and blower

- A/C system pressures are measured and compared to manufacturer's specifications
- A/C system is leak tested
- Both the heater and A/C are performance tested by checking the outlet air temperature at the discharge vents
Oil change
Check the owner's manual to see if your driving habits are considered to be "severe service." This type of driving requires more frequent oil changes, warns the Car Care Council. Have the oil changed accordingly, usually every 3-5,000 miles. For less wear and tear on the engine, drivers in cold climes (sub-zero driving temperatures) should drop their oil weight from 10-W30 to 5-W30. Your mom and dad would probably suggest simply moving to someplace warmer.
Description: The typical oil filter consists of a high-strength steel housing containing various types of filtering media. An anti-drainback valve prevents oil from running out of the filter when the engine is off. Today's oil filters have a convenient spin-on design that makes removal and installation easy.
Purpose: The oil filter sifts out contaminants, allowing the oil to flow through the engine unrestricted. Should the oil filter become restricted or clogged with contaminants, they will flow around the filter. This bypassing is a safety mechanism, but you never want to let oil and filter changes go so long that bypassing takes place.
Maintenance Tips/Suggestions: For best results, consult your owner's manual, but consider that your driving probably constitutes a severe maintenance schedule. Usually, this means oil and filter changes every 3,000 miles or 3 months. If you change the filter yourself, dispose of it properly. Take used filters to a facility that accepts them. Used filters can be crushed, removing the used oil and the steel part of the filter can be recycled. The oil from one used, seemingly innocent filter leaking into a landfill can taint 62,000 gallons of ground water.

Tires & Wheels: Tire Rotation
Description: Tire rotation refers to the regular practice of switching the position of each tire on the car.
Purpose: Tire rotation helps to equalize tread wear and is critical to gain the maximum life from your tire investment.
Maintenance Tips/Suggestions: Refer to your owner's manual for the recommended rotation interval and pattern; generally a rotation interval of 6,000 miles is recommended. The rotation pattern varies with different makes and models, which shows the tire locations during rotation. Some vehicles have different size tires on the front and back or directional tires. This limits the locations that a tire may take on the vehicle. When in doubt, check the owner's manual or consult a professional technician for guidance. Tire rotation time also offers a good opportunity to have the tires and wheels balanced. It's another step you can take to maximize your tire investment.

Tires & Wheels: Wheel Balance
Description: Wheel balance refers to the proper distribution of weight around a revolving tire and wheel assembly. Poor wheel balance can have a marked impact on both your car and your safety.
Purpose: Proper wheel balance ensures that the wheels, while spinning, do not have a heavy spot that can cause vibration and premature wear of tires, struts, shocks and other steering and suspension components. When combined with proper wheel alignment, balanced wheels ensure smooth and enjoyable driving.
Maintenance Tips/Suggestions: The most common signs of unbalanced tires are vibration and noise problems. When driving with an out-of-balance wheel, the wheel literally bounces down the road rather than spinning smoothly. This can affect the speed, handling and mileage of your car. Many of today's cars have lightweight suspension systems and are therefore, more sensitive to imbalance than older cars. It's a good idea to have your car's wheels balanced when rotating the tires, about every 6,000 miles. It's not uncommon for wheels to lose a wheel weight from time to time; so periodic balancing minimizes the impact of unbalanced wheels on your car.

Tire Repair
One of the leading causes of tire failure and casing rejection during the retread process is a faulty repair. This area is most often overlooked when fleets design tire maintenance programs, but as a recent survey from the monthly magazine Tire Business indicates, 46% of tire failures were caused by improper repair procedures. Of course this means higher tire costs.
When a radial tire has been damaged to the point where the steel cords are exposed to the elements it is important that the area be repaired as soon as possible so that moisture is not allowed to migrate along the belt package causing further damage.
The most effective method of repair for nail holes (1/4") is the plug and patch repair. The plug stops the migration of moisture and the patch on the inside of the tire supports the plug. For repairs larger than a nail hole (3/8" and larger) the tire should be removed from service.
This method of repair not only reduces the number of tire failures but promotes casing recovery as well.
Engine Diagnostics
In order to meet Federal Exhaust Emission and Fuel Economy regulations, today's vehicles are equipped with highly sophisticated electronic engine control systems. These systems do not require periodic adjustments. The only services required on a scheduled basis are spark plug and filter replacement. Tune-ups, as we knew them, are no longer necessary.
Engine Control Computer
The computer receives information from a network of sensors and switches that convert engine operating conditions into electrical signals. Based on the information and instructions stored in the computer program, commands are then sent to three primary systems:
- Ignition System
- Fuel System
- Emission Control System
The sensors that monitor one or more of these systems include:
- 1. Mass Airflow Sensor
- 2. Throttle Position Sensor
- 3. Manifold Absolute Pressure Sensor
- 4. Coolant Temperature Sensor
- 5. Exhaust Oxygen Sensor
- 6. Crankshaft Position Sensor
- 7. Camshaft Position Sensor
Suspension and Steering Systems
The primary function of your cars suspension and steering systems is to allow the wheels to move independently of the car, while keeping it "suspended" and stable. Any play or uncontrolled motion in these systems results in a deterioration of handling and accelerated tire wear. Vehicle alignment is closely tied to the condition of the suspension and steering systems.
Steering Systems
Worn or loose components affect the ability to control the toe angle, and may result in a loss of directional stability and accelerated tire wear. The main components of a Conventional system are:
- 1. Steering Gear Box
- 2. Center Link
- 3. Pitman Arm
- 4. Idler Arm
- 5. Tie Rods
The main components of a Rack and Pinion steering system are:
- 6. Rack and Pinion Assembly
- 7. Bellows Boots
- 8. Tie Rods
Suspension System
Worn or loose components affect the suspension systems ability to control motion and alignment angles, resulting in a deterioration of vehicle handling and stability, and accelerated tire wear. The main components of the suspension system are:
- 9. Control Arms
- 10. Ball Joints
- 11. Springs (Coil or Leaf)
- 12. Shock Absorbers
- 13. Struts

Wheel Alignment
Wheel alignment is the position of the wheels relative to your car. When properly aligned, the wheels point in the right direction. Without proper alignment, the wheels resist your steering commands, as well as each other. Alignment also affects gas mileage and tire wear. If your tires are pointed in different directions, they fight against each other and can cause tread wear.
Computerized alignment equipment is used to measure all alignment angles on today's cars. These include both adjustable and non-adjustable angles. (Non-adjustable angles require repair or replacement of the suspension component.) The most common adjustable angles are:
Toe
This refers to the tilted direction of the wheels toward or away from one another when viewed from the top. Toe is the most critical tire wearing angle. Tires that "toe-in" point toward one another. Tires that "toe-out" point away from each other.
Camber
This refers to the tilt of the wheels toward or away from one another when viewed from the front. Wheels that tilt in toward the vehicle have "negative camber." Wheels that tilt away from the vehicle have "positive camber."
Caster
This refers to the angle of the steering axis in relation to an imaginary vertical line through the center of the wheel when viewed from the side. "Positive caster" is the term used when the vertical line is tilted back toward the rear. If it's tilted forward, we call it "negative caster." The proper caster angle stabilizes your car for better steering.
Thrust Angle
This refers to the relationship of all four wheels to each other, as well as their relationship to an imaginary center line that runs from bumper to bumper. The term "thrust line" refers to the direction in which the rear wheels are pointed. Thrust angle is correctable on cars with adjustable rear suspensions. If your car has a non-adjustable suspension, thrust angle is compensated for by aligning the front wheels to the rear wheels.

Tire Dictionary
Air Pressure
Check the pressure in your tires at a minimum of once per month and before long trips when your tires are cool. Your tires can be considered cool after the vehicle has been stopped for at least 3 hours and driven less than one mile. Adjust to the vehicle manufacturer's specified pressure while tires are cold. Never bleed or reduce air pressure when tires are hot. It is normal for pressure to build up as a result of driving. Use an accurate tire gauge to check pressure and maintain it at the level recommended by the vehicle manufacturer. Keep your tire within the manufacturer's specified pressure range. Ignoring this recommendation may result in unexpected loss of vehicle control or accidents.
Alignment of Vehicle
If you notice that your vehicle pulls to the left or right of the road while driving with the wheel in the 12 o' clock position, you may need a wheel alignment. A wheel alignment places all four wheels of the vehicle parallel, or aligned, to one another. The aligned tires are also adjusted to be perpendicular with the ground. Properly aligned wheels help with ease of steering and will distribute general wear on your tires evenly.
All Season Tires
All season tires are tires designed to be used throughout the year. These tires are designed specifically to handle mud and snow conditions. To spot an all season tire, look for the marking "MS", "M/S", "M+S", or "M&S" on the tire's sidewall. The Rubber Manufacturer's Association (RMA) defines a standard criteria for all season tires. In essence, the tire must have several large gaps over the entire length of the tread, with the gap space being at least 25% of the tread surface. The exact specification, as taken from the RMA Snow Tire Definitions for Passenger and Light Truck (LT) Tires, is as follows:
- 1. New tire treads shall have multiple pockets or slots in at least one tread edge that meet the following dimensional requirements based on mold dimensions:
- a. Extend toward the tread center at least 1/2 inch from the footprint edge, measured perpendicularly to the tread centerline.
b. A minimum cross-sectional width of 1/16 inch.
c. Edges of pockets or slots at angles between 35 and 90 degrees from the direction of travel.
2. The new tire tread contact surface void area will be a minimum of 25 percent based on mold dimensions.
General mud and snow all season tires are not required to be industry tested. For this reason, the "Severe Snow Use" tire indicator symbol is used for all season tires that have passed a RMA specification testing standard.
ABS / Anti-Lock Brake System
In traditional non-abs vehicle braking systems, applying pressure to the brakes in hazardous road conditions or emergency situations can cause the wheels to lock up and prevent the driver from steering the vehicle. These traditional systems require the driver to "pump" the brakes in order to prevent this loss of control. In emergency situations, the driver may not remember or be able to do this.
Anti-Lock brake systems electronically and precisely control brake application by automatically "pumping" the brakes (at a much faster rate than a driver can) and adjusting brake fluid levels at each of the vehicle's wheels, something the driver of traditional braking systems cannot manually accomplish. Drivers with ABS systems should NOT pump the brakes, as the system will handle this for them. A driver can tell the ABS system is working when a slight vibration can be felt on the pedal and a low buzzing heard when braking. The result of braking with an ABS system is full steering control during maximum braking conditions.
ASC / Anti-Slip Control
Vehicles in traditional systems may experience one of two tires on an axle to slip and spin without traction while the other tire does not move. In systems using anti-slip control, the power is distributed between the tires proportional to how each tire is moving. In the example, the tire that is spinning will receive less power and the stationary tire will receive more. This effect gives the vehicle more efficient use of traction.
Balancing
Tires cannot be manufactured perfectly, and therefore slight variations can cause the weight of the the tire to be uneven. At high rotational speeds of the tire, this imbalance can cause the tire to wobble and generate vibrations. Tires are tested at the manufacturer and at the time of installation to find these imperfections. To counter the wobble effect, small metal weights are applied to the wheel rim which help to give the tire a uniform weight distribution and reduce vibration.
Bead
The bead is that part of the tire that sits on the rim of the wheel and locks the tire into place. The locking effect of the bead is supported by the air pressure within the tire.
Braking distance
The distance required for braking depends on the speed of the vehicle, the condition of the road surface and the condition of the tires, particularly the tread. Keep your braking distance to a minimum by changing worn brake pads in a timely manner and replacing tires when necessary. Most tires have a tread wear indicator that will alert you to the need to replace the tire. Check these often to maintain best performance.
Camber
Camber is the the measured angle between the vertical axis of a vehicle's tire and the road. Essentially, this is a measure of how much a tire tilts into or away from the vehicle. When the tire tilts away from the vehicle, it is known as positive camber. When the tire tilts toward the vehicle, it is known as negative camber.
Camber affects the handling of a vehicle. When there is zero camber on a tire, or no tilt, the tire's tread contact with the road is maximized on flat, straight surfaces. During cornering, however, a zero camber tire will begin to lift it's outside edge off of the ground, which results in reduced handling. This affect is commonly aided with the use of negative camber.
Casing
Modern tires are made of many different materials and components. Tires are constructed in many different ways.
Casing components may include steel and/or textile cord plies, the inner liner (to make tube-less tires airtight), sidewalls, the apexes, the bead core (keeps the tire on the rim) and the bead reinforcement. There are several standard variations on this casing, or core:
Bias
Bias, or cross ply, casings consist of ply cords that angle across the width of the tire from bead to bead, generally at a 30 to 40 degree angle. A second set of metal ply cords run in the opposite angle, creating a crisscross ply effect. The benefit of this design is a smoother, quieter ride, but forfeits handling and traction at high speeds.
Radial
Radial tires have body cords that run across the tire nearly perpendicular to the beads. Radial tires have belt plies, which are laid diagonally under the tread to stabilize and strengthen the tread area and add flexibility to the sidewall. By restricting tread movement during contact with the road, the belt plies increase improve tread life, traction, and handling.
Chains
Even modern winter tires sometimes can't help when there are huge amounts of snow and steep gradients. In these situations, traction, lateral control, and reliable braking require the help of tire chains. In order to be prepared for chain use during hazardous winter conditions, it is recommended to fit chains in a "dry run". Snow chains are used only for conditions in which traction is greatly reduced and is not intended for high speeds. With some low profile tires, the reduced space between the tires and the wheel arch leaves no room to fit snow chains. Use chains with caution.
Date of Manufacture
The date of manufacture of a tire is indicated on the tire's sidewall at the end of the DOT serial number.
Tire manufacturers have adopted a standard identification system using four numbers which indicate the week and the year of manufacture. For example, the figures 0201 indicate that the tire was made in the second week of the year 2001.
Direction of Rotation
On standard tires with symmetrical tread patterns, it does not matter which way the tire is fitted on the rim and in which position it is fitted on the car. Some tire manufacturers have, however, started producing tires with specific directions of rotation in order to improve wet grip and reduce noise generation. The direction of rotation is marked on the side of the tire with an arrow. This side of the tire must be on the outside, and the tire must roll forward in the direction of the arrow for optimum tire performance. A number of tires with asymmetric tread patterns are also now available which do not have a specific direction of rotation.
DOT Serial Number
The "DOT" symbol certifies the tire manufacturer's compliance with the U.S. Department of Transportation tire safety standards. The DOT serial number is located on the lower sidewall of the tire, on one side only. Below is a description of the serial number. Starting in the year 2000, four numbers are used for the Date of Manufacture, the first two numbers identify the week and the last two numbers identify the year of manufacture. Prior to year 2000 three numbers are used for the Date of Manufacture, the first two numbers identify the week and the last number identifies the year of manufacture. To identify tires manufactured in the 90's a decade symbol (a triangle on its side) is located at the end of the DOT serial number.
For Example: DOT NJ HR 2AE2 529
DOT: Reference Symbol (certifies the tire manufactures compliance with U.S. Department of Transportation tire safety standards).
NJ: Manufactures Plant Identification Code
HR: Tire Size Code Number.
2AE2: Tire Type Code (coding for type of tire optional by manufacture).
529: Date of Manufacturer, example: 529 (52nd week of 1999) or 5200 (52nd week of 2000).
ESC / Electronic Stability Control
In traditional vehicle systems, vehicle stability is manually maintained by the driver. If the driver encounters a hazardous situation in which control of the vehicle is lost, the driver must take the appropriate actions necessary to regain control. Electronic stability control systems attempt to take these corrective actions for the driver. The system senses a loss of control in the vehicle and will apply precise braking to each of the four wheels independently in order to regain control and move the vehicle towards the driver's intended direction. In some systems, engine power is also reduced as needed.
Emergency Mobility Systems
If a standard tire is punctured and looses air pressure, a temporary spare tire must be put on in order to avoid towing the vehicle to a maintenance shop. In order to avoid the troublesome, sometimes dangerous, procedure of changing a tire on the open road, various manufacturers now offer what is known as emergency mobility systems. This system is a special tire technology that allows the tire to be driven on for a short amount of time with no air pressure to get the vehicle to a maintenance shop.
Hydroplaning
"Water skiing on the road."
Hydroplaning is an effect that occurs on wet roads, when the contact between the tire and the road is separated by a thin layer of water. Tires are designed to handle this effect with the use of grooves in the treads, allowing a place for the water to accumulate instead of between the tire and the road. The faster a vehicle travels and the less percentage of grooves on the tire's surface results in a much higher degree of hydroplaning and the potential for the vehicle to lose control and glide across the road. Although tires are designed with sophisticated tread patterns to handle this, the best method is to slow down in hazardous conditions.
Load Index, Ply Rating and Load Range
Load range is a rating system for light truck (LT) tires which indicates both ply rating and load pressure. Load range is a letter, B-F, found on the tire sidewall. Load Index is a rating system for passenger (P) tires that indicates the maximum load that the tire can carry. Load Index is a non-decimal number between 60 and 120 and is found on the tire's sidewall.
Mixing Tires
It is recommended that all four tires be of the same size, construction and speed rating. If tires of different speed rating are mounted on a vehicle, the vehicle speed capability will be limited to the lowest speed-rated tire on the vehicle. It is recommended that the lower speed-rated tires be placed on the front axle regardless which axle is driven. This should be done to prevent a potential over steer condition. Vehicle handling may also be affected. Consult the tire manufacturer for specific guidelines on your tire.
Radial Tires
Radial tires have body cords that run across the tire nearly perpendicular to the beads. Radial tires have belt plies, which are laid diagonally under the tread to stabilize and strengthen the tread area and add flexibility to the sidewall. By restricting tread movement during contact with the road, the belt plies increase improve tread life, traction, and handling.
Reinforced or XL (extra load) Tires
Reinforced or XL (extra load) tires are specially reinforced tires. They can carry higher loads than a tire of the same size. Reinforced tires are designated on the sidewall by the letters "RF", and extra load tires are designated with the letters "XL". Reinforced and XL tires generally require higher inflation pressure compared to standard tires of the same size.
Revolutions Per Mile (RPM)
The number of revolutions a tire makes in one mile at a given load, speed, and inflation. Sometimes measured as RPK, or revolutions per kilometer.
Rolling Resistance
Rolling resistance is the restrictive force placed on a tire by the driving surface. To put a free rolling tire into motion, there must be enough force applied to the tire to overcome the opposite force placed on the tire by rolling resistance. In order to reduce rolling resistance, manufacturers use special rubber compounds. Any reduction in the rolling resistance of the tire helps reduce fuel consumption, however, strategic use of rolling resistance can aid the driver in reduced braking. Since rolling resistance is directly affected by tire pressure, it is beneficial to check the pressure of tires regularly.
Rotation
It is recommended to rotate your tires every 6,000 to 8,000 miles, or sooner if uneven tread wear begins to appear. The purpose for regular rotation is to achieve more uniform tread wear on all tires on your vehicle. This is true for both front wheel and rear wheel drive vehicles. Full size spare tires should be included in the rotation pattern for your vehicle. Compact spares (temporary use spares) should not be included in the rotation pattern.
Refer to your Vehicle Owners Manual for recommended rotation pattern and interval for your vehicle. If tires show uneven tread wear, ask your serviceperson to check and correct any alignment or other mechanical problem before rotation.
Speed Rating
The speed ratings for a tire is indicated on the sidewall of the tire by a letter or letter and number. Each speed rating indicates the maximum speed at which the tire is designed to be safely driven. Speed ratings are based on laboratory tests which relate to performance in the road, but are not applicable if tires are under inflated, overloaded, worn out, damaged or altered.
Example: Tire Size P215/60R15 H - the H indicates a maximum permitted speed of 130 MPH.
Temporary Spare Tires
Temporary spares are designed to carry the same load as the standard size tire on your vehicle and can be applied to any position. Maintain the proper inflation pressure as shown on the sidewall of the tire, which generally requires a higher inflation pressure than a standard size tire. Refer to the information on the sidewall of the tire for proper usage & speed restrictions. With such a tire, a vehicle may be operated until it is convenient to repair or replace the disabled tire. Have your standard tire repaired or replaced as soon as possible, then return the temporary spare to the trunk to conserve its useable tread life. The temporary tire can be worn down to the tread wear indicators, just like your standard tire.
Tire Size Designation
The dimensions of a tire are detailed on the sidewall.
In the case of a P185/65R 14 tire, the figures mean the following: 185 = width of tire in mm; 65 = the ratio of the height to the width as a percentage; R = radial construction; 14 = diameter of the rim in inches.
Tire Storage
Tires should be stored in a dry, cool place, away from sunlight and sources of ozone, such as electric motors.
If you must store tires flat, (one on top of the other), make sure you don't stack too many on top of each other. Too much weight can damage the bottom tire.
Also be sure to allow air to circulate around all sides of the tires, including underneath, to prevent moisture damage.
If storing tires outdoors, protect them with an opaque waterproof covering and elevate them from the ground. Do not store tires on or over black asphalt or other heat-absorbent or reflective surfaces, such as snow-covered ground or sand. Solvents, fuels, lubricants and chemicals should be kept out of contact with tires.
Spare tire carriers on your vehicle are not intended to be used for long term tire storage. If your vehicle has a full size tire (same size and type tire recommended for use by the vehicle manufacture not temporary use spares) as a spare, it should be included in the tire rotation pattern.
Toe
Toe describes the angle at which the leading edge of a pair of tires is out of parallel. When a pair of wheels is set to point slightly toward each other, it is known as toe-in. When a pair of tires is set slightly away from each other, it is known as toe-out. Toe-in is used for increased straight line driving stability and will result in less responsive turning. Toe-out will result in slightly exaggerated movements and faster turning response. Generally, most vehicles are not performance racing vehicles, which sacrifice stability for turning (toe-out), and will want slight positive toe-in for stability. If you expect your vehicle to have neutral or slightly toe-in and you notice excessive wear, particularly on only one side (the inner or outer side) of the tire, you may be experiencing toe-in or toe-out. Your vehicle may need alignment maintenance if this is unexpected.
Tread
The tread is that part of the tire with the groove pattern which is in contact with the road. The tread is specifically design to provide traction for stopping, starting, cornering and provide long lasting wear.
Tread Depth
The measured distance from the tread surface to the bottom of the main grooves away from the Tread Wear Indicators. Usually specified in 1/32 of an inch.
TWI (tread wear indicator)
Tread wear indicators ("wear bars") are located at the base of the main grooves and are equally spaced around the tire. Always remove tires from service when they reach a remaining tread depth of two thirty-seconds of an inch (2/32"). If not corrected, wet weather accidents are more likely to happen due to skidding on bald or nearly bald tires. Also, excessively worn tires are more susceptible to damage from road hazards. Built-in tread wear indicators, or "wear bars," which look like narrow strips of smooth rubber across the tread, will appear on the tire when that point of wear is reached. When you see these wear bars, the tire is worn out and it's time to replace the tire.
UTQG (Uniform Tire Quality Grading)
Treadwear
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test track. A tire graded 200 would wear twice as long on the government test course under specified test conditions as one graded 100. It is wrong to link tread wear grades with your projected tire mileage. The relative performance of tires depends upon the actual conditions of their use and may vary due to driving habits, service practices, differences in road characteristics and climate.
Traction
Traction grades, from highest to lowest, are AA, A, B and C. They represent the tire's ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete.
Temperature
The temperature grades, from highest to lowest, are A, B and C. These represent the tire's resistance to the generation of heat when tested under controlled conditions on a specified indoor laboratory test wheel.
Valve
The valve, fitted in the wheel, ensures that the tire can be filled with air. The correct valve is required for the correct wheel/tire assembly, which is the job of the tire dealer. A slow loss of air pressure may be a sign of a defective valve. The valve cap should always be fitted to the valve in order to protect the valve core from dirt and moisture.
Valve Cap
The valve cap, although small, has a very important job: it protects the sensitive valve internals from dust, dirt and humidity. If valve caps are lost they should be replaced immediately in order to avoid expensive damage later.
Winter Tires
In snowy areas, many cities and counties have "snow emergency" regulations which are invoked during heavy snowfalls. Motorists are subject to fines if they block traffic and do not have winter tires on their vehicles. Check with authorities for the rules in your area.
You can avoid this by equipping your vehicle with winter tires marked "MS," "M&S," or "M + S" on the sidewall and severe snow marking. If you change to winter tires, be sure they are the same size and construction type as the other tires on the vehicle. It is recommended that winter tires be applied on all four positions, but it is acceptable to install winter tires only on the rear position of a rear wheel drive vehicle. If winter tires are installed on the front position of any vehicle, they must also be installed on the rear position. Without winter tires on the rear, vehicle handling can be adversely affected. This may result in loss of vehicle control which could cause serious injury or death. If winter tires with a lower speed rating than listed on the vehicle placard are installed for use in winter conditions, the speed capability of the vehicle is reduced to the speed rating of the winter tires.
In areas where heavy snowfalls are frequent, many drivers carry chains for use in emergencies, or have their tire dealer install studded winter tires or tires for use in severe snow conditions. Most states have time limits on the use of studs. Before installing studded tires, check the regulations in your area. If studded tires are applied to the front axle, they also must be applied to the rear axle. If you use chains, make sure they are the proper size and type for your tires, otherwise they may damage the tire sidewall and cause tire failure. Tires designed for use in severe snow conditions generally have tread patterns, structure, and materials to give superior performance. These tires are marked with the "M+S" designation plus a mountain/snowflake symbol.
Driving Tips for Wet Roads
Driving in the rain can be dangerous; in fact thousands of car accidents each year are caused by wet driving conditions.
Routinely Check Your Tires
It is a good idea to always check your tires before you hit the road. To ensure your tires are working at their best, make sure you do the following routine maintenance:
- Keep your tires properly inflated. The correct air pressure for your tires is specified by the vehicle manufacturer and can be found on the vehicle placard located on door edge, door post, glove box door or fuel door. It is also listed in the owners manual. The number listed on the side of the tire is not the recommended air pressure for your tire -- it is the maximum air pressure for the tire.
You should check your tire's air pressure at least once a month. - Check the tires tread depth. Tires should have minimum 1/16 inch tread depth. Proper tread depth will help prevent skids and hydroplanning.
- Have your tires rotated at least every 6,000 - 8,000 miles. This will aid in detecting alignment problems and help prevent irregular wear.
Slow Down
As rain falls, it mixes with grime and oil on the road creating slick conditions perfect for skids. The best way to avoid skidding is to slow down. Driving at a slower pace allows more of the tires tread to make contact with the road, which leads to better traction.
Recover From a Skid
Skids can even happen to the most cautious drivers. If your car does skid, remember not to slam on the brakes, and do not pump the brakes if you have an anti-lock braking system (ABS). Instead apply pressure to the brakes in a firm manner and steer the car in the direction of the skid.
Keep a Safe Distance
It takes about three times longer to break on wet roads than on dry roads. Since more distance is required to brake, it is important not to tailgate. Keep a little more than two car lengths between you and the vehicle in front of you.
Recover from Hydroplaning
When it rains, water creates a barrier between the road and your tires. The liquid film that forms can cause you to loose traction and glide or hydroplane across the waters surface. If this happens, do not hit the brakes. It is better to take your foot off the gas, hold the steering in place, and lightly apply the breaks. If you have a manual transmission, push in the clutch and let the car slow down on its own.
How to build a radial tire.
Tires are not just round and black they are sophisticated products that can take years of research and development to produce. If you have ever wondered how tires are made, the following is a roadmap for the construction of a radial tire:
Start with Rubber and Additives
Tire construction starts when raw chemical additives such as sulfur, carbon black and solvents are combined with natural and synthetic rubber. The process takes place in a large machine called a banbury.
In addition to mixing and grinding, the banbury heats the rubber to make it workable in preparation for further applications. The raw product emerges in the form of long, flat bands of rubber, which are then worked in rolling mills.
Six Main Components
It takes several machines to shape the rubber into the individual components of the tire: tread, ply, belts, beads, sidewalls, and innerliner.
- The tread rubber is extruded through a tuber, then measured, cooled and cut into precise lengths.
- Sidewalls are also extruded through tubers, along with the white rubber for a white sidewall or white lettered tire if required.
- The ply is produced in a calender mill, which combines thin sheets of rubber with nylon or polyester cord fabrics. The large sheets are cut to width, rolled and transported to the assembly area where all the components will come together.
- At the same time as the raw rubber is transformed into the tread and plies, the creel room equips the tire with its basic strength. Fine steel wire goes into the manufacture of belts for the steel-belted radial tire. Rubber from the mills and steel from the creel room are molded together into wide flat sheets, cut on the bias, rolled, and moved to the tire-building machine.
- The innerliner is a impermeable layer of rubber on the inside of a tire which creates a airtight chamber when fitted to the vehicle wheel. This layer eliminates the need for a innertube.
- The last major component of the tire is the bead. The beads are created out of wrapped steel wire, covered with rubber and formed into hoops. The bead anchors the fabric plies of the tire and seats the tire firmly on the wheel.
The Green Tire
The six components (tread, ply, belts, sidewalls, liner and beads) come together on the tire-building machine. These six components are assembled into what is known as an uncured, or green, tire in two stages.
- The carcass of the tire, including beads, plies, sidewalls and liner, is constructed on one side of the machine.
- The tread and the underlying belts are assembled next to the carcass on the other side of the machine.
The two subassemblies are then joined together and the result is a green tire.
Vulcanization
The next phase is vulcanization, the molecular transformation of the soft, gummy green tire into the tough, and longwearing, modern passenger tire. The green tire is placed in a curing mold and is subjected to intense pressure and high heat internally and externally for a specified period of time. Simultaneously, the tread pattern is imprinted onto the rubber. When it comes from the mold, the tire is ready for final finish and inspection.
Final Finish and Inspection
For showroom quality, any excess rubber is trimmed off the cured tire. Every tire is thoroughly inspected. The tire then undergoes various uniformity checks to assess ride and comfort quality. Once the tires have passed all the checks and inspections, they are sent to the distribution warehouse for shipment.
Tire Tips and Maintenance
Your tires are the only part of your vehicle that actually touches the road when you drive. It only takes a couple of minutes of maintenance each month to keep your tires working at their best.
Check Your Air Pressure Once a Month
Incorrect air pressure is the leading cause of tire damage. To avoid tire damage you need to check your tire's air pressure once a month.
The correct tire pressure is listed on the vehicle placard & can be found in the following places:
- In the car owner's manual
- Under the gas tank lid
- Along the driver's side door edge
- Along the door post
The air pressure listed on the side of your tire is NOT the correct air pressure for your vehicle. That number is the maximum air pressure for the tire. Remember to check the air in your spare tire.
Don't get stranded or put out costly towing expenses. Check your air pressure on your spare regularly. Note: If you have different rims than came on your vehicle originally, make sure that the bolts on your spare tire are the correct fitting.
Failure to keep your tires properly inflated can increase wear and will have a negative effect on your vehicles handling.
When checking and adjusting tire pressure, the following should be kept in mind:
- Check the air pressure when the tire is cold - tires become hot even after driving just a mile. If you must drive to add air, check your air pressure before you leave. Air pressure changes 1-2 pounds for every 10 degrees of temperature change. Air pressure goes up in warm weather and down in cold weather.
- Tire pressure must be the same on the tires of each axle, but may be different on the front and rear axle.
- Valve caps must be tightly closed to protect the valve from dust and dirt and prevent it from leaking.
- Replace missing valve caps without delay.
Take this opportunity to inspect your tires to make sure there is nothing stuck in them or they have no deformities.
Tread Depth
To prevent hydroplaning and skidding your tires must have proper tread depth. The minimum tread depth is 1/16th of and inch.
Ask anyone, the easiest way to check your tread depth...the penny test. What is the penny test? Take a penny and place it in the tread of your tire. If part of Lincoln's head is covered by the tread your tires have enough tread. If you can see Lincoln's entire head, you should buy a new tire.
You should also check your tire tread for uneven wear. Irregular wear shortens the life of your tires, if you think you have uneven wear you should take you vehicle to your tire dealer.
Rotation
The best way to prevent uneven wear is to have your tires rotated every 6,000 - 8,000 miles or as specified in your vehicle's owner manual.
Potential Tire Troubles
- Curbs can prove to be big trouble to your tires. Approach curbs with care, if you drive over them too fast or at the wrong angle the impact may cause the tire to crack.
- Avoid potholes or debris in the road when possible.
- Avoid fast stops & starts.
- Be sure to check your owner's manual for your vehicles maximum load. Overloading your vehicle can shorten your tires life.
Replacing Your Tires
You should replace your tires with the same type of tires that came on your vehicle original equipment. This includes tire size, type and speed rating.
Proper tire care is simple and easy
Proper tire care is simple and easy. The Rubber Manufacturer's Association (RMA) recommends getting into the habit of taking five minutes each month to check your tires.

History of the Passenger Tire
The Evolution of the Passenger Tire
Dateline 3500 B.C.--Today man invented the greatest invention ever seen, THE WHEEL!
Thousands of years later, the wheel has come a long way. For one thing it is no longer made of wood and it is guaranteed that the ride is much smoother. What hasn't changed is the fact it is still one of man's greatest inventions. Could you even imagine where we would be today without it?
The early wheel was very simple...a solid curved piece of wood, then leather was eventually added to soften the ride, as time progressed it became solid rubber which led to today's tire--the pneumatic, or air inflated, radial tire.
The first wheels made of metal or wood were very durable but did not provide a very comfortable ride. The nearest thing to the first tire was a metal hoop. There were many individuals that made contributions in creating the tire as we think of it today.
Vulcanization and Charles Goodyear
Rubber was not always as useful as it is today. Early rubber did not hold shape; it would be sticky in hot weather and become inflexible in the cold.
In 1839 Charles Goodyear was credited with the discovery of the vulcanization process. Vulcanization is the process of heating rubber with sulfur. This transforms sticky raw rubber to firm pliable material which makes rubber a perfect material for tires.
The story of Charles Goodyear is a sad one, although he dedicated his entire life to making rubber a better form he would never profit from all his work. Charles Goodyear died bankrupt.
Forty years later a rubber company would honor his hard work by using his name for their new tire company.
Solid Rubber Tires
Soon, after the discovery of vulcanization tires were made out of solid rubber. These tires were strong, absorbed shocks and resisted cuts and abrasions. Although they were a vast improvement, these tires were very heavy and did not provide a smooth ride.
Today there are still types of tires made of solid rubber
Pneumatic Tires
The pneumatic rubber tire uses rubber and enclosed air to reduce vibration and improve traction. Robert W. Thomson, a Scottish engineer, first patented the air filled tire. Unfortunately the idea was too early for its time and was not a commercial success.
In 1888 John Boyd Dunlop of Belfast, Ireland became the second inventor of the pneumatic tire. Dunlop claimed to have no knowledge of Thomsons earlier invention.
The second time around the pneumatic tire caught the publics attention. The timing was perfect because bicycles were becoming extremely popular and the lighter tire provided a much better ride.
Bias Ply Tires
For the next fifty years vehicle tires were made up of an inner tube that contained compressed air and an outer casing. This casing protected the inner tube and provided the tire with traction.
Layers called plys reinforced the casing. The plys were made of rubberized fabric cords that were embedded in the rubber. These tires were known as bias-ply tires. They were named bias ply because the cords in a single ply run diagonally from the beads on one inner rim to the beads on the other. However, the orientation of the cords is reversed from ply to ply so that the cords crisscross each other.
Today you can still find bias-ply tires as authentic equipment for antique and collector cars, as well as for certain type of off-the-road tractor tires.
Radial Tires
Michelin invented radial tires in 1948 and they were first introduced in Europe that year. Radial tires are so named because the ply cords radiate at a 90 degree angle from the wheel rim, and the casing is strengthened by a belt of steel fabric that runs around the circumference of the tire.
Radial tire ply cords are made of nylon, rayon, or polyester. The advantages of radial tires include longer tread life, better steering and less rolling resistance, which increases gas mileage. On the other hand, radials have a harder riding quality, and are about twice as expensive to make.
Driving Tips for Winter
Problems always seem to happen at the most inconvenient times. Sufficient planning and preparation can make the difference between a minor inconvenience and a potentially dangerous situation.
The leading cause of death during winter storms is auto accidents. Below are preventative tips to keep you safe on the road this winter. You may not be able to control Mother Nature but using caution and common sense can prevent an accident.
- Always know the weather before you get on the road. Remember to be extra careful when driving on bridges and overpasses; they are the first to freeze over. Be aware of black ice. Black ice occurs when the road appears to be dry but is darker and shinier than usual. Slow down when driving through these areas.
- Always Buckle Up!
- Slow Down (this includes turning, braking, stopping and accelerating).
- Stay Alert. Make sure you are aware of what the other drivers around you are doing.
- Stay in Control. If you do begin to fishtail, turn in the direction of the skid and make sure to keep your foot off of the brake and gas pedals. If you must brake on a slippery surface, be sure to pump the brakes gently unless you have ABS (Anti-lock Braking System). If you have ABS, press the brake firmly and hold. Do not pump the brakes if you have ABS-this will lessen the effect of your brakes.
- Avoid steep hills if possible. Use alternate routes even if they are a little longer-they may be safer.
- Keep enough distance between yourself and other cars. Slick conditions can triple the distance it takes to come to a complete stop.
- Keep your low beam headlights on...no matter what time of day it is.
Reading Your Sidewall - Understanding Tire Hieroglyphics
Understanding Tire HieroglyphicsThere is a lot to learn from the sidewall of your tire. Although at first glance you may think you stumbled across tire hieroglyphics, you've actually found molded into the tires side its own user manual.
Tire Size
Example P205/55R16 91W
- P identifies your tire as a Passenger Tire. The P stands for PMetric. If your tire size starts with LT rather than a P than it identifies the tire as a light truck tire.
- 205 identifies the tire section width, which is the measurement of the tire from sidewall to sidewall in millimeters. This measurement varies depending on the rim to which it is fitted.
(There are 25.4 millimeters per 1 inch.) - 55 is the two-figure aspect ratio. This percentage compares the tires section height with the tires section width. For example, this aspect ratio of 55 means that the tires section height is 55% of the tires section width.
- R indicates the construction used within the tires casing. R stands for radial construction. B means belted bias and D stands for diagonal bias construction.
- 16 The last dimension listed in the size is the diameter of the wheel rim which is most often measured in inches.
Load Index and Speed Rating
- 91 The load index and speed rating, or service description are the numbers that follow the tire size.
The load index tells you how much weight the tire can support when properly inflated. Load indices range from 74 - 150 for passenger tires with each numeric value corresponding to a certain carrying capacity. The carrying capacity for each value can be found on a load index chart. On each U.S. passenger car tire, the load limit is listed in pounds. European tires have the load limit listed in kilograms and sometimes pounds. - W Speed ratings are represented by letters ranging from A to Z. Each letter coincides to the maximum speed a tire can sustain under its recommended load capacity. For instance, S is equivalent to a max speed of 112 mph. Even though a tire can perform at this speed, we do not advocate exceeding legal speed limits.
| Speed Symbol | Speed (km/h) | Speed (mph) |
| A1 | 5 | 3 |
| A2 | 10 | 6 |

DOT Serial Number
The "DOT" symbol certifies the tire manufacturer's compliance with the U.S. Department of Transportation tire safety standards.
Below is a description of the serial number. Starting with the year 2000, four numbers are used for the Date of Manufactuer, first two numbers identify the week and the last two numbers identify the year of manufacture.
Prior to year 2000 three numbers are used for the Date of manufacture, first two numbers identify the week and the last number identifies the year of manufacture. To identify tires manufactured in the 90's a decade symbol (a triangle on its side) is located at the end of the DOT serial number.
