Temperature

The temperature grades are A (the high-

est), B, and C, representing the tire’s resis-

tance 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 tem-

perature can cause the material of the tire

to degenerate and reduce tire life, and ex-

cessive 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 perfor-

mance on the laboratory test wheel than

the minimum required by law.

Warning G

The temperature grade for this tire is estab-

lished for a tire that is properly inflated and

not overloaded. Excessive speed, underin-

flation, or excessive loading, either sepa-

rately or in combination, can cause

excessive heat build-up and possible tire

failure.
