We've been helping people find the right tires, wheels and performance parts since 1979. If you're looking for the best and most accurate information on all things tires, you've come to the right place.
A tire's most important job is to carry the load required of it, and the load range/ply rating branded on the tire's sidewall indicates how much load the tire is designed to carry (at a specific pressure). Whenever changing tire sizes or from one tire type to another, it's important to ensure...
A load index is an assigned numerical value that signifies a tire's maximum load carrying capacity. They're useful to help compare load carrying capacity of different-sized tires, and as you might expect, the higher the tire's load index number, the greater its load carrying capacity. Using the...
*Fuel Economy, That is. And More. Maintaining correct tire inflation pressure helps optimize tire performance and fuel economy. Correct tire inflation pressure allows drivers to experience tire comfort, durability and performance designed to match the needs of their vehicles. Tire deflection...
Flat tires can happen any time and usually occur when it's least convenient. And while having a flat tire can be upsetting in itself, being stranded waiting for help can be even more distressing. Having a properly inflated spare tire in the trunk allows drivers and/or roadside assistance...
When Buying a Pair of Tires It's best to replace all of a vehicle's tires at the same time. Having the same tread design and tread depth promotes balanced traction and handling. However if only a pair of tires is replaced, the two new tires are to be installed on the rear axle with the...
Racing tires, even those required by competition rules to meet U.S. Department of Transportation (DOT) standards, are designed first-and-foremost to win races. And in order to accomplish that goal, they are manufactured with minimum weight to deliver maximum performance. Lightweight racing...
Tires branded with MOExtended or MOE on their sidewalls identify them as being specifically tuned for Mercedes-Benz vehicles. The Extended portion of the name identifies they feature run-flat-like tire characteristics by offering temporary extended mobility. However, since they don't meet all...
European Union (EU) tire labeling regulations for passenger car and light truck tires went into effect November 1, 2012. These regulations help harmonize consumer information on a new tire's wet braking ability and environmental impact related to the tire's contribution to vehicle efficiency...
A safety recall involving a motor vehicle or an item of motor vehicle equipment can be voluntarily conducted by its manufacturer or ordered by the U.S. National Highway Traffic Safety Administration (NHTSA). The U.S. Transportation Recall Enhancement, Accountability and Documentation (or...
How Slow Do You Have to Go? The origin of tire speed ratings can be traced to Europe where they were needed to match high-speed tire durability with the unlimited vehicle speeds permitted on roadways like the German Autobahn. And even though the highest speed limit in the United States is 85...
In order to preserve the integrity of the installed studs: the rolling direction of studded tires should never be changed. To achieve the best possible wintertime performance and longest lifetime from a set of studded tires, they should be rotated periodically to equally share the vehicle's...
Like the motorsports tires they have evolved from, all Track & Competition DOT performance category tires feature constructions and compounds that have been tuned to maximize traction and performance within a range of warm-to-hot ambient temperatures. Therefore, unlike less highly tuned...
Like the motorsports tires they have evolved from, all Extreme Performance Summer performance category tires feature constructions and compounds that have been tuned to maximize traction and performance within a range of warm-to-hot ambient temperatures. Therefore, unlike less highly tuned...
Studs for tires used in winter driving feature a tungsten carbide pin encased in a cylindrical metal housing that looks like a carpenter nail with its shaft cut short. Typically 80 to 100 studs per tire are inserted into small holes molded in the tire's tread design. The tire's tread is often...
