VEHICLE CARE 301
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 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, causing a
crash. Always use the correct wheel,
wheel bolts, and wheel nuts for
replacement.
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.
Used Replacement Wheels
{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. When replacing
wheels, use a new GM original
equipment wheel.
Tire Chains
{Warning
If the vehicle has 235/55R20 size
tires, do not use tire chains. There
is not enough clearance. Tire chains
used on a vehicle without the
proper amount of clearance 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
(Continued)

Warning (Continued)
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 235/55R20, 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(Continued)
Caution (Continued)
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 Tires0282.
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.

13. Lower the vehicle by turning thejack handle counterclockwise.
{Warning
Wheel nuts that are improperly or
incorrectly tightened can cause the
wheels to become loose or come off.
The wheel nuts should be tightened
with a torque wrench to the proper
torque specification after replacing.
Follow the torque specification
supplied by the aftermarket
manufacturer when using accessory
locking wheel nuts. See Capacities
and Specifications 0346 for original
equipment wheel nut torque
specifications.
Caution
Improperly tightened wheel nuts
can lead to brake pulsation and
rotor damage. To avoid expensive
brake repairs, evenly tighten the
wheel nuts in the proper sequence
(Continued)
Caution (Continued)
and to the proper torque
specification. SeeCapacities and
Specifications 0346 for the wheel
nut torque specification.
14. Tighten the wheel nuts firmly in a crisscross sequence, as shown.
15. Lower the jack all the way and remove the jack from under the
vehicle.
16. Tighten the wheel nuts firmly with the wheel wrench. When reinstalling the wheel cover or
center cap on the full-size tire, tighten
all six plastic caps hand snug with the
aid of the wheel wrench and tighten
them with the wheel wrench an
additional one-quarter of a turn.
Caution
Wheel covers will not fit on the
vehicle's compact spare. If you try
to put a wheel cover on the
compact spare, the cover or the
spare could be damaged.
Storing a Flat or Spare Tire and
Tools
{Warning
Storing a jack, a tire, or other
equipment in the passenger
compartment of the vehicle could
cause injury. In a sudden stop or
collision, loose equipment could
strike someone. Store all these in
the proper place.

VEHICLE CARE 315
To store the flat or spare tire and
tools:1. Open the liftgate. See Liftgate
0 23.
2. Replace the tools as they were stored in the rear storage
compartment and put the
compartment cover back on.
3. Place the tire, lying flat, in the rear storage compartment.
4. Place the loop end of the strapthrough the cargo tie-down.
Place the hook end of the strap through the loop and pull it until
the strap is fastened securely to
the tie-down.
5. Route the strap hook through the
wheel, as shown.
6. Attach the strap to the other cargo tie-down in the rear of the
vehicle.
7. Tighten the strap and secure it using the buckle.
The compact spare is for temporary
use only. Replace the compact spare
tire with a full-size tire as soon as
you can.
Compact Spare Tire
{Warning
Driving with more than one
compact spare tire at a time could
result in loss of braking and
handling. This could lead to a crash
and you or others could be injured.
Use only one compact spare tire at
a time.
If this vehicle has a compact spare
tire, it was fully inflated when new;
however, it can lose air over time.
Check the inflation pressure regularly.
It should be 420 kPa (60 psi).
Stop as soon as possible and check
that the spare tire is correctly inflated
after being installed on the vehicle.
The compact spare tire is designed for
temporary use only. The vehicle will
perform differently with the spare tire
installed and it is recommended that
the vehicle speed be limited to
80 km/h (50 mph). To conserve the
tread of the spare tire, have the
