characteristics and climate.
TRACTION
The traction grades, from highest to lowest, are AA, A, B, and C, as measured under controlled
conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have
poor traction performance.
WARNING!
The traction grade assigned to this tire is based on braking (straight-ahead) traction tests and is not a
measure of cornering (turning) traction.
TEMPERATURE
The temperature grades are AA (the highest), A, 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 minimum level of performance which all passenger car tires must meet under the Federal Motor
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.
