Tire Information
Temperature
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 condi-
tions on a specified indoor laboratory
test wheel. Sustained high tempera-
ture 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 labora-
tory test wheel than the minimum
required by law.

Warning: The temperature grade for
this tire is established for a tire that
is properly inflated and not over-
loaded. Excessive speed,
underinflation, or excessive loading,
either separately or in combination,
can cause heat build-up and possible
tire failure.
