Wheels and Tires
Traction
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 . Those 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
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 test 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.
