Warning
Using bias-ply tyres on the vehicle
may cause the wheel rim flanges to
develop cracks after many miles of
driving. A tyre and/or wheel could
fail suddenly and cause a crash. Use
only radial-ply tyres with the wheels
on the vehicle.
Winter tyres with the same speed
rating as the original equipment tyres
may not be available for H, V, W, Y and
ZR speed rated tyres. Never exceed the
winter tyres' maximum speed capability
when using winter tyres with a lower
speed rating.
If the vehicle tyres must be replaced
with a tyre that does not have a TPC
Spec number, make sure they are the
same size, load range, speed rating, and
construction (radial) as the original
tyres.
The Tyre and Loading Information label
indicates the original equipment tyres
on the vehicle. See
.
Different Size Tyres and Wheels
If wheels or tyres are installed that are a
different size than the original equipment
wheels and tyres, vehicle performance,
including its braking, ride and handling
characteristics, stability, and resistance to
rollover may be affected. If the vehicle has
electronic systems such as antilock brakes,
rollover airbags, traction control, electronic
stability control, or All-Wheel Drive, the
performance 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.

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. If the
wheel leaks air, replace it. Some aluminium
wheels can be repaired. See your dealer if
any of these conditions exist.
