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

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

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

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).

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".

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 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.

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

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

Shipping weight (lbs)

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

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

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