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 t.ested 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
A
and
B
represent higher levels
of
perfolmance 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.

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.

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
Cadillac 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.
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
Cadillac model.
