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.

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

Load Range

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

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

Tread Design

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

Section Width

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