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.
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
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
wneels, which can sometimes be repaired). See
your
Aurora retailer
if
any
of
these conditions exist.
Your retailer 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
Aurora model.
I
Using the wrong replacement wheels, wheel bolts
or wheel nuts on your vehicle can be dangerous.
It could affect the braking and handling of your
vehicle, make your tires lose air and make you
lose control. You could have
a
collision in which
you or others could be injured. Always use the
correct wheel, wheel bolts and wheel nuts for
replacement.
