Temperature
--
A,
B,
C
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.
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, underinflation, or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory to give you the longest tire life
and best overall performance.
Scheduled wheel alignment and wheel balancing are
not needed. However,
if
you notice unusual tire wear or
your vehicle pulling one way or the other, the alignment
may need to be reset.
If
you notice your vehicle
vibrating when driving on a smooth road, your wheels
may need to be rebalanced.
Wheel Replacement
Replace
any
wheel that is bent, cracked, or badly rusted
or corroded. If wheel nuts keep coming loose, the wheel,
wheel bolts and wheel nuts should be replaced.
If
the
wheel leaks air, replace it (except some aluminum
wheels, which can sometimes be repaired). See your
dealer
if
any of these conditions exist.
Your dealer will know the kind of wheel youneed.
Each new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted the
same way as the one it replaces.
If you need to replace any
of
your wheels, wheel
bolts or wheel nuts, replace them only with new GM
original equipment parts. This way, you will be sure to
have the right wheel, wheel bolts and wheel nuts for
your Buick model.
