Warning: The temperature grade for

this tire is established for a tire that

is properly inflated and not

overloaded. Excessive speed,

underinflation, or excessive loading,

either separately or in combination,

can cause heat buildup and possible

tire failure.

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 represent

higher levels of performance on the

laboratory test wheel than the

minimum required by law.
