J
Temperature A, B, C
The temperature grades are A (highest), B and C, representing the tire’s
resistance to 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. Grade C corresponds to a level of performance
which all passenger car tires must meet under the Federal Motor Vehicle
Safety Standards 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 a tire is established for one that is
properly inflated and not overloaded. Excessive speed, under
inflation or excessive loading, either separately or in combina-
tion, can cause heat buildup and possible tire failure.
