Different Size Tires and Wheels
If you add wheels or tires that are a different size
than your original equipment wheels and tires,
this may affect the way your vehicle performs,
including its braking, ride and handling
characteristics, stability, and resistance to rollover.
Additionally, if your vehicle has electronic
systems such as, anti-lock brakes, traction control,
and electronic stability control, the performance
of these systems can be affected.
{CAUTION:
If you add different sized wheels, your
vehicle may not provide an acceptable
level of performance and safety if tires not
recommended for those wheels are
selected. You may increase the chance
that you will crash and suffer serious
injury. Only use GM specic wheel and
tire systems developed for your vehicle,
and have them properly installed by a
GM certied technician.SeeBuying New Tires on page 420and
Accessories and Modications on page 353for
additional information.
Uniform Tire Quality Grading
Quality grades can be found where applicable on
the tire sidewall between tread shoulder and
maximum section width. For example:
Treadwear 200 Traction AA Temperature A
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration (NHTSA), which
grades tires by treadwear, traction, and
temperature performance. This applies only to
vehicles sold in the United States. The grades are
molded on the sidewalls of most passenger car
tires. The Uniform Tire Quality Grading (UTQG)
system does not apply to deep tread, winter-type
snow tires, space-saver, or temporary use
spare tires, tires with nominal rim diameters of
10 to 12 inches (25 to 30 cm), or to some
limited-production tires.

Tire Chains
{CAUTION:
Do not use tire chains. There is not enough
clearance. Tire chains used on a vehicle
without the proper amount of clearance
can cause damage to the brakes,
suspension or other vehicle parts. The area
damaged by the tire chains could cause
you to lose control of your vehicle and you
or others may be injured in a crash.
CAUTION: (Continued)
CAUTION: (Continued)
Use another type of traction device only if
its manufacturer recommends it for use
on your vehicle and tire size combination
and road conditions. Follow that
manufacturer’s instructions. To help avoid
damage to your vehicle, drive slowly,
readjust or remove the device if it is
contacting your vehicle, and do not spin
your vehicle’s wheels. If you do nd
traction devices that will t, install them
on the front tires.

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.After you have put the spare tire on your vehicle,
store the at tire in your trunk.
Store the at tire as far forward in the trunk as
possible. Store the jack and wheel wrench in their
compartment in the trunk. For storage, the jack
must be raised until the screw end is ush with the
edge of the jack.
The compact spare is for temporary use only.
Replace the compact spare tire with a full-size tire
as soon as you can.
437

After installing the compact spare on the vehicle,
stop as soon as possible and make sure the
spare tire is correctly inated. 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 nish your trip and have
the full-size tire repaired or replaced at your
convenience. Of course, it is best to replace the
spare with a full-size tire as soon as possible. The
spare tire will last longer and be in good shape
in case it is needed again.
Notice:When the compact spare is installed,
do not take your vehicle through an automatic
car 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.
Do not use the compact spare on other vehicles.
And do not mix the compact spare tire or
wheel with other wheels or tires. They will not t.
Keep the spare tire and its wheel together.
Notice:Tire chains will not t your compact
spare. Using them can damage your vehicle
and can damage the chains too. Do not use tire
chains on your compact spare.Spare Tire
Your vehicle may have a spare tire, which, when
new, was fully inated. A spare tire may lose
air over time, so check its ination pressure
regularly. SeeInation - Tire Pressure on
page 411andLoading Your Vehicle on page 333
for information regarding proper tire ination
and loading your vehicle. For instructions on how
to remove, install or store a spare tire, see
Removing the Flat Tire and Installing the Spare
Tire on page 431.
After installing the spare tire on your vehicle, you
should stop as soon as possible and make
sure the spare is correctly inated. Have the
damaged or at road tire repaired or replaced as
soon as you can and installed back onto your
vehicle. This way, a spare tire will be available in
case you need it again.
Your vehicle may have a different size spare tire
than the road tire originally installed on your
vehicle. This spare tire was developed for use on
your vehicle, so it is all right to drive on it.
If your vehicle has a spare tire that does not
match your vehicle’s original road tires and wheels
in size and type, do not include the spare in the
tire rotation.
