9-29INSPECTION AND MAINTENANCE
80J21-03E
Temperature – A, B, C
The temperature grades are A (the high-
est), B and C, representing the tire’s resis-
tance 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 tem-
perature 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. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law.
Tire Rotation
54G114
To avoid uneven wear of your tires and to
prolong their life, rotate the tires as illus-
trated. Tires should be rotated as recom-
mended in the periodic maintenance
schedule. After rotation, adjust front and
rear tire pressures to the specification
listed on your vehicle’s Tire and Loading
Information Label.
WARNING
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Exces-
sive speed, underinflation or exces-
sive loading, either separately or in
combination, can cause heat buildup
and possible tire failure.
WARNING
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose after
a time. The wheel could come off and
cause an accident. When you change
a wheel, remove any rust or dirt from
places where the wheel attaches to
the vehicle. In an emergency, you can
use a cloth or a paper towel to do
this; but be sure to use a scraper or
wire brush later, if you need to, to get
all the rust or dirt off.
