WARNING!
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
.
Temperature Grades
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 sud-
den tire failure
. The grade C corresponds to a level of performance, which
all passenger vehicle tires must meet under the Federal Motor Vehicle 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
.
