Wheel Alignment and Tire Balance
The tires and wheels on your vehicle were
aligned and balanced carefully at the factory to
give you the longest tire life and best overall
performance. Adjustments to wheel alignment
and tire balancing will not be necessary on
a regular basis. However, if you notice unusual
tire wear or your vehicle pulling to one side or the
other, the alignment may need to be checked.
If you notice your vehicle vibrating when driving
on a smooth road, your tires and wheels may
need to be rebalanced. See your dealer for
proper diagnosis.
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 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 vehicle.
{CAUTION:
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.
