Traction AA A B C
Note:
The traction grade assigned to this tire is based on straight-ahead
braking traction tests, and does not include acceleration, cornering,
hydroplaning or peak traction characteristics.
The traction grades, from highest to lowest are AA, A, B, and C.
The grades represent the tire’s ability to stop on wet pavement as
measured under controlled conditions on specified government test
surfaces of asphalt and concrete. A tire marked C may have poor
traction performance.
Temperature A B C
WARNING:
The temperature grade for this tire is established
for a tire that is properly inflated and not overloaded. Excessive
speed, underinflation, or excessive loading, either separately or in
combination, can cause heat buildup and possible tire failure.
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 car tires must meet under the Federal Motor Vehicle Safety
Standard No. 139. Grades B and A represent higher levels of performance
on the laboratory test wheel than the minimum required by law.
