9-9
The relative performance of tires depends
upon the actual conditions of their use,
however, and may depart significantly
from the norm because of variations in
driving habits, service practices and
differences in road characteristics and
climate.
J
Traction—AA, A, B, C
The traction grades from highest to lowest,
are AA, A, B and C. Those grades repre-
sent the tire’s ability to stop on wet pave-
ment as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction perfor-
mances.
WARNING
Tire Traction Grade:
The traction grade assigned to this
tire is based on braking (straight
ahead) traction tests and does not
include acceleration, cornering
(turning), hydroplaning or peak
traction characteristics.
J
Temperature—A, B, C
The temperature grades, A (the highest),
B, and C, represent the tire’s resistance
to the generation of heat and its ability
to dissipate heat when tested under con-
trolled conditions on a specified indoor
laboratory test wheel.
Sustained high temperatures can cause
the material of the tire to degenerate
and reduce tire life, and excessive tem-
peratures can lead to sudden tire failure.
Grade C corresponds to a level of perfor-
mance which all passenger vehicle tires
must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades
B and A represent higher levels of perfor-
mance on the laboratory test wheel than
the minimum required by law.
