5-30 Storing a Flat or Spare Tire and Tools
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.
1. Put the flat tire on the ground at the rear of the
vehicle with the valve stem pointed down.
2. Tilt the retainer plate downward and through the
wheel opening. Make sure it is fully seated across the
underside of the wheel. Attach the ratchet, with the
UP side facing you, to the extension.3. Put the flat end of the extension on an angle through
the hole in the rear door frame, above the bumper.
Keep turning the ratchet until you feel at least two
clicks when the tire is up all the way.
The compact spare is for temporary use only.
Replace the compact spare tire with a full
-size tire as
soon as you can. See ªCompact Spare Tireº in the
Index. See the storage instructions label to restore
your compact spare properly.
4. Raise the tire fully against the underside of the
vehicle. Continue turning the ratchet/wheel wrench
until the tire is secure and the cable is tight.
The spare tire hoist cannot be overtightened.

5. Make sure the tire is stored securely. Push, pull, and
then try to rotate or turn the tire. If the tire moves,
use the ratchet/wheel wrench to tighten the cable.
Return the jacking equipment to its proper location.
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
60 psi (420 kPa).
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.

6-51 Buying New Tires
To find out what kind and size of tires you need,
look at the Certification/Tire label.
The tires installed on your vehicle when it was new had
a Tire Performance Criteria Specification (TPC Spec)
number 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 ªMSº
(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.
CAUTION:
Mixing tires could cause you to lose control while
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.
CAUTION:
If you use bias-ply tires on your vehicle, the
wheel rim flanges 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.

6-55
Used Replacement Wheels
CAUTION:
Putting a used wheel on your vehicle is dangerous.
You can't know how it's been used or how far it's
been driven. It could fail suddenly and cause a
crash. If you have to replace a wheel, use a new
GM original equipment wheel.
Tire Chains
NOTICE:
Use tire chains only where legal and only when
you must. Use only SAE Class ªSº type chains that
are the proper size for your tires. Install them on
the rear axle tires and tighten them as tightly as
possible with the ends securely fastened.
Drive slowly and follow the chain manufacturer's
instructions. If you can hear the chains contacting
your vehicle, stop and retighten them. If the
contact continues, slow down until it stops.
Driving too fast or spinning the wheels with
chains on will damage your vehicle.
