When rotating your tires, always use the correct rotation
pattern shown here.
Do not include the compact spare tire in your tire
rotation.
After the tires have been rotated, adjust the front and
rear ination pressures as shown on the Tire and
Loading Information label.
Make certain that all wheel nuts are properly tightened.
See “Wheel Nut Torque” underCapacities and
Specications on page 5-98.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make 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
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 5-73.

{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 5-83.
{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.
Your vehicle’s original equipment tires are listed on
the Tire and Loading Information Label. This label
is attached to the vehicle’s center pillar (B-pillar).
SeeLoading Your Vehicle on page 4-31, for more
information about the Tire and Loading Information
Label and its location on your vehicle.

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 5-66andAccessories
and Modications on page 5-3for 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.
While the tires available on General Motors passenger
cars and light trucks may vary with respect to these
grades, they must also conform to federal safety
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.

wheel wrench (C).
Removing the Flat Tire and
Installing the Spare Tire
If the vehicle has steel wheel covers with center caps,
the wheel nuts are hidden behind the cap. To remove
the wheel cover, do the following:
1. Pry off the center cap by using the at end of the
wheel wrench at the notch on the cap.
5-76

2. Use the wheel wrench to loosen the plastic wheel
nut caps, if equipped, in a counterclockwise
direction.
If needed, nish loosening them by hand. The nut
caps will not come off of the wheel cover.
3. Use the at end of the wheel wrench and pry along
the edge of the cover until it comes off. Pull off the
wheel cover and set it aside.
The edge of the wheel cover could be sharp, so do
not try to remove the cover with your bare hands.
Do not drop the cap or lay it face down, as it could
become scratched or damaged.
If the vehicle has aluminum wheels and wheel center
caps, the wheel nuts are hidden behind the center cap.
Pry off the center cap by using the at end of the
wheel wrench at the notch.
Do not drop the cap or lay it facedown, as it could
become scratched or damaged.Once you have removed the wheel cover or center
cap, use the following procedure to remove the at tire
and install the spare tire.
1. Place the wheel wrench securely over the wheel
nut. Turn the wheel wrench counterclockwise
to loosen all the wheel nuts, but do no remove
them yet.
2. Turn the jack handle clockwise to raise the jack
lift head.
5-77

3. Find the jacking location using the diagram above
and corresponding hoisting notches located on the
underside of the vehicle’s plastic molding. The
notches in the plastic molding are marked with a
triangle shape to help you nd them.
The front location is about 6.5 inches (16.5 cm)
from the rear edge of the front wheel well. The
rear location is about 9 inches (22.8 cm) from the
front edge of the rear wheel well.
4. 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.
