Your spare tire is stored underneath the rear of your
vehicle. See ªCompact Spare Tireº later in this section
for more information about the compact spare.
NOTICE:
Never remove or store a tire from/to a storage
position under the vehicle while the vehicle is
supported by a jack. Always tighten the tire
fully against the underside of the vehicle when
storing it.
Insert the chisel end
of the wheel wrench, on
an angle, into the hole in
the rear bumper.
Be sure the chisel end of the wheel wrench connects into
the hoist shaft.

Turn the wheel wrench counterclockwise to lower the
spare tire. Keep turning the wheel wrench until the spare
tire can be pulled out from under the vehicle.
When the tire has been completely lowered, tilt the
retainer at the end of the cable and pull it through the
wheel opening. Pull the tire out from under the vehicle.
NOTICE:
To help avoid vehicle damage, do not drive the
vehicle before the cable is restored.
Put the spare tire near the flat tire.The tools you'll be using include the jack (A) and wheel
wrench (B). Your vehicle may also have an optional hub
cap removal tool.

5-22
Position the bent end of your hub cap removal tool
(shown), or the chisel end of your wheel wrench, in the
notch of the hub cap and pry off the hub cap.
Some of the molded plastic hub caps have imitation
wheel nuts molded into them. The wheel wrench won't
fit these imitation nuts, so don't try to remove them with
the socket end of the wheel wrench.If you have individual wheel nut caps that cover each
nut, they must be removed in order to get to the wheel
nuts. Use the socket end of the wheel wrench to remove
the wheel nut caps.
Your wheel nut caps may attach your hub cap to the
wheel. Remove these wheel nut caps before you take off
the hub cap.

CAUTION:
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.
CAUTION:
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.4. Raise the vehicle by turning the jack handle clockwise.
Raise the vehicle far enough off the ground so there is
enough room for the spare tire to fit.
5. Remove all the wheel nuts and take off the flat tire.

6. Remove any rust or dirt
from the wheel bolts,
mounting surfaces and
spare wheel.
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 you need to, to get all the rust
or dirt off.
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.
7. Place the spare on the wheel mounting surface.
8. Put the nuts on by
hand. Make sure
the cone
-shaped
end is toward
the wheel.

Tighten each nut by hand until the wheel is held
against the hub. If a nut can't be turned by
hand, use the wheel wrench and see your dealer as
soon as possible.
9. Lower the vehicle by turning the jack handle
counterclockwise. Lower the jack completely.
10. Use the wrench to
tighten the wheel
nuts firmly in a
crisscross sequence
as shown.

5-27
CAUTION:
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to become loose
and even come off. This could lead to an accident.
Be sure to use the correct wheel nuts. If you have
to replace them, be sure to get new GM original
equipment wheel nuts.
Stop somewhere as soon as you can and have
the nuts tightened with a torque wrench to
100 lb
-ft (140 N´m).
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.

CAUTION:
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.

Don't use the existing hoist to store a tire with an
aluminum wheel or it could damage the wheel.
Secure the tire in the pickup bed.
