Ultra High Performance (or UHP) tires have a speed rating of V or greater and are used on sports cars, super cars, and other powerful vehicles. Commonly featuring a wide footprint and low profile, UHP tires provide excellent traction and steering response but should not be used when temperatures are at 40 degrees or below.

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.

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

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

The maximum carrying capacity for a tire determined by the manufacturer

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)

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.

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

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

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

The range of widths the rim of the vehicle can be for this tire to be safely mounted on

The measurement of width from a tires inner sidewall to the outer sidewall

The diameter of a tire that is inflated without any load applied
