When rotating your tires, always use the correct
rotation pattern shown here.
Do not include the compact spare tire in your tire
rotation.
After the tires have been rotated, adjust the front
and rear ination pressures as shown on the
Tire and Loading Information label.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specications on page 503.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a time. The wheel
could come off and cause an accident.
When you change a wheel, remove any
rust or dirt from places where the wheel
attaches to the vehicle. In an emergency,
you can 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. SeeChanging a Flat Tire on
page 470.

GM’s exclusive TPC Spec system considers over
a dozen critical specications that impact the
overall performance of your vehicle, including
brake system performance, ride and handling,
traction control, and tire pressure monitoring
performance. GM’s TPC Spec number is molded
onto the tire’s sidewall by the tire manufacturer.
If the tires have an all-season tread design,
the TPC spec number will be followed by an MS
for mud and snow. SeeTire Sidewall Labeling
on page 450for additional information.
{CAUTION:
Mixing tires could cause you to lose
control while driving. If you mix tires of
different sizes, brands, or types (radial
and bias-belted tires), the vehicle may not
handle properly, and you could have a
CAUTION: (Continued)
CAUTION: (Continued)
crash. Using tires of different sizes,
brands, or types may also cause damage
to your vehicle. Be sure to use the correct
size, brand, and type of tires on all
wheels. It is all right to drive with your
compact spare temporarily, as it was
developed for use on your vehicle. See
Compact Spare Tire on page 486.
{CAUTION:
If you use bias-ply tires on your vehicle,
the wheel rim anges could develop
cracks after many miles of driving. A tire
and/or wheel could fail suddenly, causing
a crash. Use only radial-ply tires with the
wheels on your vehicle.

2. Turn the folding wrench counterclockwise to
lower the compact spare tire (D) to the
ground. Continue to turn the wrench so the
compact spare tire can be pulled out from
under the vehicle.
3. Tilt the retainer at the end of the cable to
remove the compact spare tire, so it can
be pulled up through the wheel opening.The hoist is used to store a full-size or a at
road tire under the vehicle. SeeStoring a
Flat or Spare Tire and Tools on page 483for
more information.
4. Remove the compact spare tire from the
cable.
If the compact spare tire will not lower, check
under the vehicle to see if the tire is hanging loose
and the cable end and spring under the wheel
plate are missing. If so, the secondary latch
system is engaged. SeeSecondary Latch System
on page 481.
To continue changing the at tire, seeRemoving
the Flat Tire and Installing the Spare Tire on
page 474.
Removing the Flat Tire and
Installing the Spare Tire
Your vehicle may have aluminum wheels. If so, you
will see exposed stainless steel wheel nuts. Use the
wheel wrench to loosen all of the wheel nuts. Do not
remove them yet. Or, your vehicle may have steel
wheel covers. To remove the wheel covers and
wheel nut caps, loosen the plastic nut caps with the
wheel wrench in a counterclockwise direction.
474

If needed, you can nish loosening with your
ngers. The plastic nut caps will not come off. Use
the at end of the wheel wrench and pry along the
edge of the cover until it comes off. The edge of the
wheel cover could be sharp, so do not try to remove
it with your bare hands. Do not drop the cover or lay
it face down, as it could become scratched or
damaged. Once you have removed the wheel
cover, use the following procedure to remove the
at tire and install the spare tire.1. Loosen the wheel
nuts using the
folding wrench,
but do not
remove them.
Turn the handle counterclockwise about
180 degrees, then ip the handle back to the
starting position. This avoids taking the
wrench off the lug nut for each turn.
Notice:If your vehicle has wheel locks and
you use an impact wrench to remove the wheel
nuts, you could damage the lock nut or
wheel lock key. Do not use an impact wrench
to remove the wheel nuts if your vehicle
has wheel locks.
475

Notice:If you use a jack to raise the vehicle
without positioning it correctly, you could
damage your vehicle. When raising your
vehicle on a jack, avoid contact with the rear
axle control arms.
Notice:If you position the jack under the
rocker molding and attempt to raise the
vehicle, you could break the molding and/or
cause other damage to your vehicle. Always
position the jack so that when the jack head is
raised, it will t rmly in the notch located
inboard from the rocker molding.
A. Front Location
B. Rear Location
2. Near each wheel, there is a notch (A and B)
in the vehicle’s frame, inboard of the rocker
molding. Position the jack and raise the
jack head until it ts rmly into the notch in
the vehicle’s frame nearest the at tire.
Do not raise the vehicle yet.
3. Put the compact spare tire near you.
476

5. Raise the vehicle by turning the folding
wrench clockwise in the jack. Raise the
vehicle far enough off the ground so there is
enough room for the compact spare tire
to t under the wheel well.
6. Remove all the wheel nuts and take off the
at tire.
{CAUTION:
Rust or dirt on the wheel, or on the parts
to which it is fastened, can make the
wheel nuts become loose after a time. The
wheel could come off and cause an
accident. When you change a wheel,
remove any rust or dirt from the places
where the wheel attaches to the vehicle. In
an emergency, you can 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.
478

7. Remove any rust or
dirt from the wheel
bolts, mounting
surfaces and spare
wheel.
{CAUTION:
Never use oil or grease on studs or nuts.
If you do, the nuts might come loose.
Your wheel could fall off, causing a
serious accident.8. Install the compact
spare tire and put
the wheel nuts back
on with the
rounded end of the
nuts toward the
wheel.
Tighten each nut by hand until the wheel is
held against the hub.
