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.
These grades are molded
on the sidewalls of passenger
car tires.
While the tires available as standard or optional
equipment
on General Motors vehicles may vary with
respect to these grades, all such tires meet General
Motors performance standards and have been approved
for use
on General Motors vehicles. All passenger type
(P Metric) tires must conform to Federal safety
requirements in addition to these grades.
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.
In most cases, you will not need to have your wheels
aligned again. 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.
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 Buick dealer if any of
these conditions
exist.
Your dealer will know the kind of wheel you need.
Each new wheel should have the same load carrying
capacity, diameter, width, offset, and be mounted the same way as
the one it replaces.
