Temperature Grades

The temperature grades are A (the highest), B, and C,

representing the tire’s resistance to the generation of heat

and its ability to dissipate heat, when tested under

controlled conditions on a specified indoor laboratory

test wheel. Sustained high temperature can cause the

material of the tire to degenerate and reduce tire life, and

excessive temperature can lead to sudden tire failure. The

grade C corresponds to a level of performance, which all

passenger car tires must meet under the Federal Motor

Vehicle Safety Standard No. 109. Grades B and A repre-

sent higher levels of performance on the laboratory test

wheel, than the minimum required by law.

WARNING!

The temperature grade for this tire is established for
a tire that is properly inflated and not overloaded.
Excessive speed, under-inflation, or excessive load-
ing, either separately or in combination, can cause
heat buildup and possible tire failure.
