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 the
vehicle is significantly pulling
to one side or the other. Some
slight pull to the left or right,
depending on the crown of theroad 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
it has been driven may be
unknown. It could fail
suddenly and cause a crash.

424 Vehicle Care
Warning (Continued)
When replacing wheels, use
a new GM original
equipment wheel.
Caution
The wrong wheel can also
cause problems with bearing
life, brake cooling,
speedometer or odometer
calibration, headlamp aim,
bumper height, vehicle
ground clearance, and tire or
tire chain clearance to the
body and chassis.
Tire Chains
{Warning
If the vehicle has 265/45R21
size tires, do not use tire
chains. There is not enough
clearance. Tire chains used
on a vehicle without the
proper amount of clearance(Continued)
Warning (Continued)
can cause damage to the
brakes, suspension, or other
vehicle parts. The area
damaged by the tire chains
could cause loss of control
and a crash. Use another
type of traction device only
if its manufacturer
recommends it for the
vehicle's tire size
combination and road
conditions. Follow that
manufacturer's instructions.
To avoid vehicle damage,
drive slow and readjust or
remove the traction device if
it contacts the vehicle. Do
not spin the wheels. If
traction devices are used,
install them on the front
tires.
Caution
If the vehicle is equipped
with a tire size other than
265/45R21, use tire chains
only where legal and only
when necessary. Use low
profile chains that add no
more than 12 mm thickness
to the tire tread and inner
sidewall. Use chains that are
the proper size for the tires.
Install them on the tires of
the front axle. Do not use
chains on the tires of the
rear axle. Tighten them as
tightly as possible with the
ends securely fastened.
Drive slowly and follow the
chain manufacturer's
instructions. If the chains
contact the vehicle, stop and
retighten them. If the
contact continues, slow
down until it stops. Driving
too fast or spinning the
wheels with chains on will
damage the vehicle.

If a Tire Goes Flat
It is unusual for a tire to blow
out while driving, especially if
the tires are maintained
properly. See Tires0400. If air
goes out of a tire, it is much
more likely to leak out slowly.
But if there is ever a blowout,
here are a few tips about what
to expect and what to do:
If a front tire fails, the flat tire
creates a drag that pulls the
vehicle toward that side. Take
your foot off the accelerator
pedal and grip the steering
wheel firmly. Steer to maintain
lane position, and then gently
brake to a stop, well off the
road, if possible.
A rear blowout, particularly on
a curve, acts much like a skid
and may require the same
correction as used in a skid.
Stop pressing the accelerator
pedal and steer to straighten
the vehicle. It may be very
bumpy and noisy. Gently brake
to a stop, well off the road,
if possible.{Warning
Driving on a flat tire will
cause permanent damage to
the tire. Re-inflating a tire
after it has been driven on
while severely underinflated
or flat may cause a blowout
and a serious crash. Never
attempt to re-inflate a tire
that has been driven on
while severely underinflated
or flat. Have your dealer or
an authorized tire service
center repair or replace the
flat tire as soon as possible.
{Warning
Lifting a vehicle and getting
under it to do maintenance
or repairs is dangerous
without the appropriate
safety equipment and
training. If a jack is provided
with the vehicle, it is
designed only for changing a
(Continued)
Warning (Continued)
flat tire. If it is used for
anything else, you or others
could be badly injured or
killed if the vehicle slips off
the jack. If a jack is provided
with the vehicle, only use it
for changing a flat tire.
If a tire goes flat, avoid further
tire and wheel damage by
driving slowly to a level place,
well off the road, if possible.
Turn on the hazard warning
flashers. See Hazard Warning
Flashers 0160.
If your vehicle is loaded at or
near maximum cargo capacity,
it may be difficult to fit the jack
under the vehicle due to the
environment (shoulder slope,
road debris, etc.). Removal of
some weight may improve the
ability to fit the jack under the
vehicle at the correct jacking
location.
