Temperature Letter - This letter indicates a tire’s resistance to heat. The temperature grade is for a tire
that is inflated properly and not overloaded. Excessive speed, under inflation or excessive loading, either
separately or in combination, can cause heat build-up and possible tire failure. From highest to lowest, a
tire’s resistance to heat is graded as “A”, “B”, or “C”.
Additional Information on Light Truck Tires
Please refer to the following diagram.
Tires for light trucks have other markings besides those found on the sidewalls of passenger tires.
LT - The “LT” indicates the tire is for light trucks or trailers.
ST - An “ST” is an indication the tire is for trailer use only.
Max. Load Dual kg (lbs) at kPa (psi) Cold - This information indicates the maximum load and tire pressure
when the tire is used as a dual, that is, when four tires are put on each rear axle (a total of six or more
tires on the vehicle).
Max. Load Single kg (lbs) at kPa (psi) Cold - This information indicates the maximum load and tire
pressure when the tire is used as a single.
Load Range - This information identifies the tire’s load-carrying capabilities and its inflation limits.

• Slow down if you have to go over a pothole or other object in the road.
