Vehicles that have a tire pressure
monitoring system may give an
inaccurate low‐pressure warning
if non‐TPC Spec-rated tires
are installed on your vehicle.
Non‐TPC Spec-rated tires may
give a low‐pressure warning that
is higher or lower than the proper
warning level you would get with
TPC Spec-rated tires. SeeTire
Pressure Monitor System
on
page 10‑65.
Your vehicle's original equipment
tires are listed on the Tire and
Loading Information label. See
Vehicle Load Limits
on page 9‑23for more information about the Tire
and Loading Information label and
its location on your vehicle.
Different Size Tires and
Wheels
If you add wheels or tires that are
a different size than your original
equipment wheels and tires, this
could affect the way your vehicle
performs, including its braking,
ride and handling characteristics,
stability, and resistance to rollover.
Additionally, if your vehicle has
electronic systems such as antilock
brakes, rollover airbags, traction
control, and electronic stability
control, the performance of these
systems can be affected.
{WARNING
If you add different sized wheels,
your vehicle may not provide an
acceptable level of performance
and safety if tires not
recommended for those wheels
are selected. You may increase
the chance that you will crash and
suffer serious injury. Only use GM
specific wheel and tire systems
developed for your vehicle, and
have them properly installed by
a GM certified technician.
See Buying New Tires
on
page 10‑75and Accessories and
Modificationson page 10‑3for
additional information.

changed. That would be the tire
on the other side, at the opposite
end of the vehicle.
When the vehicle has a flat tire (B),
use the following example as a

Rear Position–All Other Models
For all other models, position the
jack under the rear axle between
the spring anchor and the shock
absorber bracket.
If you have added a snow plow
to the front of your vehicle, lower
the snow plow fully before
raising the vehicle.
Make sure that the jack head is
positioned so that the rear axle
is resting securely between
the grooves that are on the
jack head.
{WARNING
Getting under a vehicle when it is
jacked up is dangerous. If the
vehicle slips off the jack, you
could be badly injured or killed.
Never get under a vehicle when
it is supported only by a jack.
{WARNING
Raising your vehicle with the
jack improperly positioned can
damage the vehicle and even
make the vehicle fall. To help
avoid personal injury and vehicle
damage, be sure to fit the jack
lift head into the proper location
before raising the vehicle. 6. Turn the wheel wrench
clockwise to raise the vehicle.
Raise the vehicle far enough off
the ground so there is enough
room for the spare tire to fit
under the wheel well.
7. Remove all the wheel nuts andtake off the flat tire.

{WARNING
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle.
In an emergency, use a cloth or
a paper towel to do this; but be
sure to use a scraper or wire
brush later, if needed, to get all
the rust or dirt off. SeeIf a Tire
Goes Flat on page 10‑81.
8. Remove any rust or dirt from the wheel bolts, mounting surfaces,
and spare wheel.
9. Install the spare tire.
{WARNING
Never use oil or grease on bolts
or nuts because the nuts might
come loose. The vehicle's wheel
could fall off, causing a crash.
10. Put the wheel nuts back on with the rounded end of the
nuts toward the wheel. 11. Tighten each wheel nut by
hand. Then use the wheel
wrench to tighten the nuts
until the wheel is held against
the hub.
12. Turn the wheel wrench counterclockwise to lower
the vehicle. Lower the jack
completely.
{WARNING
If wheel studs are damaged, they
can break. If all the studs on a
wheel broke, the wheel could
come off and cause a crash.
If any stud is damaged because
of a loose-running wheel, it could
be that all of the studs are
damaged. To be sure, replace all
studs on the wheel. If the stud
holes in a wheel have become
larger, the wheel could collapse in
operation. Replace any wheel if
its stud holes have become larger
or distorted in any way. Inspect

WARNING (Continued)
hubs and hub‐piloted wheels
for damage. Because of loose
running wheels, piloting pad
damage may occur and require
replacement of the entire hub, for
proper centering of the wheels.
When replacing studs, hubs,
wheel nuts or wheels, be sure to
use GM original equipment parts.
{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(Continued)
WARNING (Continued)
specification supplied by the
aftermarket manufacturer when
using accessory locking wheel
nuts. SeeCapacities and
Specifications
on page 12‑2
for original equipment wheel
nut torque specifications.
Notice: 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 and to
the proper torque specification.
See Capacities and Specifications
on page 12‑2for the wheel nut
torque specification.
13. Tighten the nuts firmly in a crisscross sequence as shown
by turning the wheel wrench
clockwise.
For vehicles with dual wheels, have
a technician check the wheel nut
tightness of all wheels with a torque
wrench after the first 100 miles
(160 km) and then 1,000 miles
(1600 km) after that. Repeat this
service whenever you have a
tire removed or serviced. See
Capacities and Specifications
on
page 12‑2for more information.
