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. 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.
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.
Driving too fast for conditions creates the possibility of
loss of vehicle control. Driving at very high speeds for
extended periods of time may result in damage to vehicle
components.
