Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
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 Is Time
for New Tires on page 5-62andWheel Replacement
on page 5-66for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The ®rst rotation
is the most important. See
Scheduled Maintenance
on page 6-4.
When rotating non-directional tires, always use the
correct rotation pattern shown here.If your vehicle has 235/40ZR18 tires, they must roll in a
certain direction for the best overall performance.
The direction is shown by an arrow on the tire sidewall.
Because these tires are uni-directional, they should
be rotated as shown here. These tires should only be
moved from front to rear and rear to front on the
same side of the vehicle.
Don't include the compact spare tire in your tire rotation.

Buying New Tires
GM has developed and matched speci®c tires for your
vehicle. The original equipment tires installed on
your vehicle, when it was new, were designed to meet
General Motors tire performance criteria. GM's tire
performance criteria considers over a dozen critical
speci®cations that impact the overall performance
of your vehicle, including brake system performance,
ride and handling, and traction control. If you need
replacement tires, GM strongly recommends that you
replace your vehicle's tires with the same size, load
range, speed rating, and construction type (radial and
bias-belted tires) as your vehicle's original tires.
This way, your vehicle will continue to have tires that
are designed to give the same performance and vehicle
safety, during normal use, as the original tires.
{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.
CAUTION: (Continued)
CAUTION: (Continued)
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 5-76.
{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.
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). See
Loading Your Vehicle on page 4-29, 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
speci®c wheel and tire systems developed for
your vehicle, and have them properly installed
by a GM certi®ed technician.
See
Buying New Tires on page 5-63andAccessories
and Modi®cations 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.

Removing the Spare Tire and Tools
The equipment you will need to change a ¯at tire is
located in the trunk.
1. Open the trunk. See
Trunk on page 2-9for more
information.
2. Lift the cover to access the compact spare tire
and tools.3. Turn the retaining bolt on the compact spare tire
counterclockwise and remove it.
4. Then lift the compact spare tire out of the vehicle.
See
Compact Spare Tire on page 5-76for more
information.
5. Remove the jack, wheel wrench, wheel blocks, and
nut cap removal tool from the container in the trunk,
which are stored under the compact spare tire.

Removing the Flat Tire and
Installing the Spare Tire
To remove the wheel nut caps, do the following:
1. Remove each wheel nut cap with the wheel nut cap
tool provided. Insert the nut cap tool into the nut
cavity, squeeze the tool to grasp the nut cap,
and pull out to remove it.
If the nut caps are hard to remove, use the tip of
the wheel wrench to remove the nut caps.2. Use the wheel wrench to loosen all the wheel nuts.
Do not remove them yet.
3. Fit the jack handle onto the jack by sliding the open
end of the handle over the nut end of the jack.
4. Position the jack and
raise the jack head
until it ®ts ®rmly into the
notches (A and B), in
the vehicle's frame
closest to the tire
being changed.
5-71

5. Put the compact spare tire near the ¯at tire.
{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.6. Raise the vehicle by turning the wheel wrench
clockwise. Raise the vehicle far enough off the
ground so there is enough room for the compact
spare tire to ®t underneath the wheel well.
The jack handle must be unfolded to a right angle
before it is used.

7. Remove all of the
wheel nuts.
8. Remove the ¯at tire.
{CAUTION:
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 needed, to get
all the rust or dirt off.
9. Remove any rust or dirt
from the wheel bolts,
mounting surfaces, and
spare tire.
