■

Temperature A, B, C

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.
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 represent higher levels of performance on the laboratory test

wheel than the minimum required by law.
Warning: The temperature grades of a tire assume that it is properly inflated and

not overloaded.

Excessive speed, underinflation, or excessive loading, either separately or in com-

bination, can cause heat buildup and possible tire failure.
