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 
performance 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.
