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 temperatures can cause the
material of the tire to degenerate and reduce tire life, and
excessive temperature can leadto suddentirefailure.The
grade C corresponds to a level of performance which all
passenger vehicle 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!
The temperature grade for this tire is established for
a tire that is properly inflated and not overloaded.
Excessive speed, under-inflation, or excessive load-
ing, either separately or in combination, can cause
heat build-up and possible tire failure.
