2008 GMC ACADIA spare wheel

Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specifications on page 5-107.
{CAUTION:
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
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 5-72.
Make sure the spare tire is stored securely. Push,
pull, and then try to rotate or turn the tire. If it
moves, tighten the cable. SeeStoring a Flat or
Spare Tire and Tools on page 5-84.
When It Is Time for New Tires
Various factors, such as maintenance, temperatures,
driving speeds, vehicle loading, and road conditions
inuence when you need new tires.
One way to tell when it is
time for new tires is to
check the treadwear
indicators, which will
appear when your tires
have only 1/16 inch
(1.6 mm) or less of tread
remaining.
5-63

GM recommends replacing tires in sets of four.
This is because uniform tread depth on all tires will
help keep your vehicle performing most like it
did when the tires were new. Replacing less than
a full set of tires can affect the braking and
handling performance of your vehicle. SeeTire
Inspection and Rotation on page 5-62for
information on proper tire rotation.
{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
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 5-88.
{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.
If you must replace your vehicle’s tires with those
that do not have a TPC Spec number, make
sure they are the same size, load range, speed
rating, and construction type (radial and
bias-belted tires) as your vehicle’s original tires.
Vehicles that have a tire pressure monitoring
system could 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 5-57.

When your vehicle has a at tire, use the following
example as a guide to assist you in the placement of
wheel blocks.
The following information tells you how to use the jack
and change a tire.

spare tire to the ground. Continue turning the
wrench until the spare tire can be pulled out from
under the vehicle.
5. Tilt the retainer and slip it through the wheel
opening to remove the spare tire from the cable.
6. Turn the wrench clockwise to raise the cable back
up after removing the spare tire.
Do not store a full-size or a at road tire under the
vehicle. SeeStoring a Flat or Spare Tire and
Tools on page 5-84.To continue changing the at tire, seeRemoving the
Flat Tire and Installing the Spare Tire (Outlook) on
page 5-76.
If the spare tire will not lower, the secondary latch could
be engaged.
5-75

Do the following to check the cable:
1. Check under the vehicle to see if the cable is
visible.
2. If it is not visible, seeSecondary Latch System on
page 5-81.
If it is visible, rst try to tighten the cable by turning
the lug wrench clockwise until you hear two
clicks or feel it skip twice. You cannot over-tighten
the cable.
3. Loosen the cable by turning the wrench
counterclockwise three or four turns.
4. If the spare tire did lower to the ground, continue
with Step 5 under “Removing the Spare Tire” listed
previously.
5. If you still cannot lower the spare tire to the ground,
seeSecondary Latch System on page 5-81.Removing the Flat Tire and
Installing the Spare Tire
1. Do a safety check before proceeding. SeeChanging
a Flat Tire on page 5-72for more information.
2. If the vehicle has a wheel cover, loosen the plastic
nut caps with the wheel wrench. They will not come
off. Then, using the at end of the wheel wrench,
pry along the edge of the cover until it comes off. Be
careful; the edges may be sharp. Do not try to
remove the cover with your bare hands.
Store the wheel cover securely in the rear of the
vehicle until you have the at tire repaired or
replaced.
If your vehicle has aluminum wheels, remove the
wheel nut caps using the wheel wrench.

5. Do not raise the vehicle yet. Put the compact spare
tire near you.
{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 t the
jack lift head into the proper location before
raising the vehicle.
6. Attach the lug wrench to the jack, and turn the
wrench clockwise to raise the jack head
3 inches (7.6 cm).7. Place the jack under the vehicle as identied in
Step 3. Raise the vehicle by turning the lug
wrench clockwise in the jack. Raise the vehicle far
enough off the ground so that there is enough
room for the spare tire to t under the wheel well.
8. Remove all the wheel nuts and the at tire.
9. Remove the plastic spare tire heat shield by pulling
the rubber latch. Store the plastic spare tire heat
shield. SeeStoring a Flat or Spare Tire and

13. Lower the vehicle by attaching the lug wrench to
the jack and turning the wrench counterclockwise.
Lower the jack completely.
{CAUTION:
Incorrect or improperly tightened wheel nuts
can cause the wheel to come loose and even
come off. This could lead to a crash. If you
have to replace them, be sure to get new
original equipment wheel nuts. Stop
somewhere as soon as you can and have the
nuts tightened with a torque wrench to the
proper torque specication. SeeCapacities
and Specifications on page 5-107for wheel nut
torque specication.
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 specication. SeeCapacities and
Specifications on page 5-107for the wheel nut
torque specication.14. Tighten the wheel nuts
rmly in a crisscross
sequence, as shown.
Notice:Wheel covers will not t on your vehicle’s
compact spare. If you try to put a wheel cover
on the compact spare, the cover or the spare could
be damaged.
