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 tires and wheels were
aligned and balanced at the
factory to provide the longest
tire life and best overall
performance. Adjustments to
wheel alignment and tire
balancing are not necessary
on a regular basis. Consider an
alignment check if there is
unusual tire wear or thevehicle is significantly pulling
to one side or the other. Some
slight pull to the left or right,
depending on the crown of the
road and/or other road
surface variations such as
troughs or ruts, is normal.
If the vehicle is vibrating when
driving on a smooth road, the
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.
Some aluminum wheels can be
repaired. See your dealer if
any of these conditions exist.
Your dealer will know the kind
of wheel that is needed.
Each new wheel should have
the same load-carrying
capacity, diameter, width,
offset, and be mounted the
same way as the one it
replaces.
Replace wheels, wheel bolts,
wheel nuts, or Tire Pressure
Monitor System (TPMS)
sensors with new GM original
equipment parts.
{Warning
Using the wrong
replacement wheels, wheel
bolts, or wheel nuts can be
dangerous. It could affect
the braking and handling of
the vehicle. Tires can lose air
and cause loss of control,
resulting in a crash. Always
use the correct wheel, wheel
bolts, and wheel nuts for
replacement.
{Warning
Replacing a wheel with a
used one is dangerous. How
it has been used or how far
