10-84 Vehicle Care
GM recommends replacing tires in
sets of four. This is because uniform
tread depth on all tires will help
keep your vehicle performing most
like it did when the tires were new.
Replacing less than a full set of tires
can affect the braking and handling
performance of your vehicle. See
Tire Inspection
on page 10‑80and
Tire Rotation on page 10‑81.
{WARNING
Tires could explode during
improper service. You or others
could be injured or killed if you
attempt to mount or dismount a
tire. Only your dealer or an
authorized tire service center
should mount and dismount the
tires.
Winter tires with the same speed
rating as your original equipment
tires may not be available for H, V,
W and ZR speed rated tires. If you choose snow tires with a lower
speed rating, never exceed the tire's
maximum speed capability.
{WARNING
Mixing tires could cause you to
lose control while driving. If you
mix tires of different sizes (other
than those originally installed on
your vehicle), 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
(other than those originally
installed on your vehicle), brands
or types, may also cause damage
to your vehicle. Be sure to use
the correct size, brand, and type
tires on all four wheels.
{WARNING
If you use bias-ply tires on the
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 the 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.

Vehicle Care 10-85
Vehicles that have a tire pressure
monitoring system could give an
inaccurate low‐pressure warning if
non‐TPC Spec rated tires are
installed on it. Non‐TPC Spec rated
tires may give a low‐pressure
warning that is higher or lower than
the proper warning level you would
get with TPC Spec rated tires. See
Tire Pressure Monitor Operation
on
page 10‑77.
Your vehicle's original equipment
tires are listed on the Tire and
Loading Information label. See
Vehicle Load Limits
on page 9‑11,
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
could 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.
See Buying New Tires
on
page 10‑83and Accessories and
Modificationson page 10‑4for
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

Used Replacement Wheels
{WARNING
Putting a used wheel on the
vehicle is dangerous. You cannot
know how it has been used or
how far it has 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
{WARNING
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 the vehicle and
you or others may be injured in a
crash. Use another type of
traction device only if its
manufacturer recommends it for(Continued)
WARNING (Continued)
use on the vehicle and tire size
combination and road conditions.
Follow that manufacturer's
instructions. To help avoid
damage to the vehicle, drive
slowly, re‐adjust or remove the
device if it is contacting the
vehicle, and do not spin the
wheels. If you do find traction
devices that will fit, install them on
the rear tires.

Compact Spare Tire
{WARNING
Driving with more than one
compact spare tire at a time could
result in loss of braking and
handling. This could lead to a
crash and you or others could be
injured. Use only one compact
spare tire at a time.
If your vehicle is equipped with a
compact spare tire it was fully
inflated when the 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 the vehicle, stop as soon as
possible and make sure the 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 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 the
vehicle through an automatic car
wash with guide rails. The
compact spare can get caught on
the rails which can damage the
tire, wheel and other parts of the
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 fit. Keep the
spare tire and its wheel together.
Notice:
Tire chains will not fit the
compact spare. Using them can
damage the vehicle and can
damage the chains too. Do not
use tire chains on the compact
spare.

11-2 Service and Maintenance
{WARNING
Performing maintenance work can
be dangerous. Some jobs can
cause serious injury. Perform
maintenance work only if you
have the required know-how and
the proper tools and equipment.
If in doubt, see your dealer to
have a qualified technician do the
work. SeeDoing Your Own
Service Work on page 10‑4. At your dealer, you can be certain
that you will receive the highest
level of service available. Your
dealer has specially trained service
technicians, uses genuine
replacement parts, as well as,
up‐to‐date tools and equipment to
ensure fast and accurate
diagnostics.
The proper replacement parts,
fluids, and lubricants to use are
listed in
Recommended Fluids and
Lubricants
on page 11‑7and
Maintenance Replacement Partson
page 11‑9. We recommend the use
of genuine parts from your dealer. Rotation of New Tires
Tire rotation is not recommended if
the vehicle has different size tires
on the front and rear wheels. If tire
rotation is recommended for the
vehicle, to maintain ride, handling,
and performance of the vehicle, it is
important that the first rotation
service for new tires be performed.
Tires should be rotated every
12 000 km/7,500 miles. See
Tire
Rotation on page 10‑81.
