Temperature Grades
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 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 loading, either separately or in combination,
can cause heat buildup and possible tire failure.
