5-22 Removing the Spare Tire and Tools
Your spare tire is stored underneath the rear of your
vehicle. You will use the ratchet and extension to lower
the spare tire.A flat rear tire reduces clearance to remove the spare
tire. If there is less than 12 inches (30.48 cm) between
the ground and the rear bumper or any trailer hitch,
jack up the vehicle until the flat tire is off the ground.
(See ªRemoving the Flat Tireº and ªInstalling the
Spare Tire,º in the Index.
Unless your vehicle has a flat rear tire, do not remove or
restore 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 restoring.
If you have a vehicle which was completed from a
cab and chassis, refer to the information from the
body supplier/installer.
The spare tire is a full
-size tire, like the other tires on
your vehicle.
6-50 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 (except some aluminum
wheels, which can sometimes be repaired). See your
dealer if any of these conditions exist.
Your dealer will know the kind of wheel you need.
Each new wheel should have the same load
-carrying
capacity, diameter, width, offset and be mounted the
same way as the one it replaces.
If you need to replace any of your wheels, wheel bolts
or wheel nuts, replace them only with new GM original
equipment parts. This way, you will be sure to have the
right wheel, wheel bolts and wheel nuts for your vehicle.
CAUTION:
Using the wrong replacement wheels, wheel bolts
or wheel nuts on your vehicle can be dangerous. It
could affect the braking and handling of your
vehicle, make your tires lose air and make you lose
control. You could have a collision in which you or
others could be injured. Always use the correct
wheel, wheel bolts and wheel nuts for replacement.
NOTICE:
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.
