of these systems can also be
affected.
Warning
If different sized wheels are used,
there may not be an acceptable
level of performance and safety if
tyres not recommended for those
wheels are selected. This
increases the chance of a crash
and serious injury. Only use GM
specific wheel and tyre systems
developed for the vehicle, and
have them properly installed by a
GM certified technician.

page 10-47 and Accessories and
Modifications on page 10-2.
Wheel Alignment and
Tyre Balance
The tyres and wheels were aligned
and balanced at the factory to
provide the longest tyre life and best
overall performance. Adjustments to
wheel alignment and tyre balancing
are not necessary on a regular
basis. Consider an alignment check
if there is unusual tyre wear or the
vehicle 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 tyres 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.
Vehicle Care
If the wheel leaks air, replace it.
Some aluminium 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, and offset, and
should be mounted the same way
as the one it replaces.
Replace wheels, wheel bolts, wheel
nuts, or Tyre 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. Tyres can lose air,
and cause loss of control, causing
