Racing Trac

Racing tires offer drivers strong performance on the drag strip, race track, street track, or dirt track. These tires are available in different varieties, but are typically built to provide quicker acceleration, responsive steering, and improved braking for faster lap times.

Passenger tires are some of the most common tires you'll find on the roads today, and frequently used on coupes, sedans, hatchbacks, minivans, and other passenger vehicles. Passenger tires are available in a wide variety of types, such as all-season, winter, and ultra-high-performance.

This product is not covered by a manufacturer’s treadlife warranty.

Mileage Warranty

The maximum carrying capacity for a tire determined by the manufacturer.

Load Index

Maximum speed capability to safely carry a load for an extended period of time.

Max Speed

The maximum load carrying strength at the specified inflation pressure, also known as ply rating.

The side of the tire between the tread and rim, with cosmetic branding as well as information about the tire including manufacturer, model, size, etc.

Sidewall

Standards that measure treadwear, temperature resistance and traction, example: "640 A A".  The 640 is the treadwear test and it lasted 6.4 times longer than the comparison tire tested against.  The first "A" is the traction rating using straight-line wet traction on test surfaces (see information tables tab) and the second "A" is the temperature rating by testing operation at high speeds without heat-related failure (see information tables tab).

UTQG

Wet Traction is a piece of the UTQG for example if  UTQG is: 500 AA A, the wet traction piece is the second piece, the "AA".

Wet Traction

Measured in 32nds of an inch, this metric shows how much tread life is left on a tire, with the tire's traction & stopping capabilities greatly diminished at 4/32nds and less. Tire manufacturers include "tire wear bars" at 2/32nds to indicate when your tire is worn out.

Tread Depth

The highest inflation pressure (measured in pounds of force per square inch, PSI) the tire is designed to contain, and should only be used when called for by the vehicle placard.

Inflation Pressure

An identifier of a particular tire line and size combination assigned by the tire manufacturer.

Part Number

Tread design (or tread pattern) can affect handling, traction & noise for different driving styles & road conditions.

Tread Design

Tire Weight

A three-peak mountain snowflake (3PMSF) symbol branded on a tire's sidewall indicates the tire meets required performance criteria in snow testing to be considered severe snow service-rated.

Three-Peak Mountain Snowflake (3PMS)

Terra Force AT

All-terrain tires offer drivers traction on- and off-road, and are typically used by light truck and SUV drivers who want a tire that's able to climb rocks and perform on the highway.

SUV/Crossover tires are designed for use on SUVs and CUVs and provide many of the same performance characteristics as passenger tires but are built to handle the heavier weight that's common from these larger vehicles.
