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.
The temperature grade for this tire is established for a tire that is properly
inflated and not overloaded. Excessive speed, under-inflation, or exces-
sive loading, either separately or in combination, can cause heat buildup
and possible tire failure.
