Removing the Flat Tire and Inst'alling the
Spare Tire
1. Use the wheel wrench to loosen the wheel nuts, but
don't remove them.
2. Attach the wheel wrench to the jack, and rotate the
wrench clockwise
to raise the jack head a few inches.
Put the jack head into a notch in the frame which
is located near each wheel well. The front notch is
10 inches (25 cm) back from the front wheel well.
The rear notch is 8 inches (20 cm) forward from the
rear wheel well.

4. Raise the vehicle by rotating the wheel wrench
clockwise
in the jack. 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.
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.

9. Tighten the wheel
nuts firmly in a
criss-cross sequence.
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 Ib-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.
Don’t try to put the wheel cover
on the compact
spare tire. It won’t fit. Store the wheel cover in the
trunk until you have replaced the compact spare tire
with a regular tire.
Wheel covers won’t fit
on your compact spare. If
you try to put a wheel cover on your compact
spare, you could damage the cover or the spare.
When
you re-install the full size wheel and tire, you
install the wheel cover or nut caps at this point.

Compact Spare Tire
Although the compact spare tire was fully inflated when
your vehicle was new, it can lose air after a time. Check
the inflation pressure regularly.
It should be 610 psi
(420 Wa).
After installing the compact spare on your vehicle, you
should stop as soon
as possible and make sure your
spare tire
is correctly inflated. The compact spare is
made to perform well at speeds up to 65 mph (105
km/h) for distances up to 3,000 miles (5 000 km), so you
can finish your trip and have your full-size tire repaired
or replaced where you want. Of course, it’s best to
replace your spare with a full-size tire as soon as you
can. Your spare will last longer and
be in good shape in
case you need it again.
NOTICE:
When the compact spare is installed, don’t take
your vehicle through an automatic vehicle wash
with guide rails. The compact spare can get
caught
on the rails. That can damage the tire and
wheel, and maybe other parts of your vehicle.
Don’t use your compact spare on other vehicles.
And don’t mix your compact spare tire or wheel with
other wheels OF tires, They won’t fit. Keep your spare
tire and its wheel together.
NOTICE:
Tire chains won’t fit your compact spare. Using
them can damage your vehicle and can damage
the chains too. Don’t
use tire chains on your
compact spare.

When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It should be at
60 psi (420 kPa).
How to Check
Use a good quality pocket-type gage to check tire
pressure.
You can’t tell if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even
when they’re underinflated.
Be sure to put
the valve caps back on the valve stems.
They help prevent leaks by keeping out
dirt and moisture.
Tire Inspection and Rotation
Tires should be rotated every 6,080 to 8,000 miles
(10 000 to 13 000 h). Any time you notice unusual
wear, rotate your tires as soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See “When It’s Time for New Tires’’
and
“Wheel Replacement” later in this section for
more information.
The purpose
of regular rotation is to achieve more
unifQm
wear .- - for .. dl tires ., on . h .. vehicle. . The first rotation
is the most important. See “Scheduled
Maintenance Services” in the Index for scheduled
rotation intervals.

When rotating your tires, always use the correct rotation
pattern shown here.
Don’t include the compact spare tire in your tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures
as shown on the Tire-Loading
Information label.
Make certain that all wheel nuts are
properly tightened. See “Wheel Nut Torque” in
the Index.

Buying New Tires
To find out what kind and size of tires you need, look at
the
Tire-Loading Information label.
The tires installed on your vehicle when it was new had
a Tire Performance Criteria Specification (TPC Spec)
numb’er on each tire’s sidewall. When you get new tires,
get ones with that
same TPC Spec number. That way
your vehicle will continue
to have tires that are designed
to give proper endurance, handling, speed rating,
traction, ride and other things during normal service
on
your vehicle. If your tires have an all-season tread
design, the TPC number will be followed by an “MS”
(for mud and snow).
If you ever replace your tires with those not having a
TPC Spec number, make sure they are the same size,
load range, speed rating and construction type (bias,
bias-belted or radial) as your original tires. Mixing tires
could cause
you to lose control w: e
driving. If you mix tires of different sizes or types
(radial and bias-belted tires), the vehicle may not
handle properly, and you could have a crash.
Using tires of different sizes may also cause
damage
to your vehicle. Be sure to use the same
size and type tires on all wheels.
It’s all right to drive with your compact spare,
though. It was developed for use on your vehicle.
