When rotating the vehicle’s tires,
always use the correct rotation
pattern shown here.
If the vehicle has a compact
spare tire, do not include it in the
tire rotation.
After the tires have been rotated,
adjust the front and rear ination
pressures as shown on the Tire
and Loading Information label.SeeInflation - Tire Pressure on
page 5-42andLoading the
Vehicle on page 4-16.
Reset the Tire Pressure Monitor
System. SeeTire Pressure
Monitor Operation on page 5-45.
Make certain that all wheel nuts
are properly tightened. See
“Wheel Nut Torque” under
Capacities and Specifications 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 time. The wheel
could come off and cause an
accident. When you change a
wheel, remove any rust or dirt
(Continued)
CAUTION (Continued)
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 5-71.
Make sure the spare tire, if the
vehicle has one, is stored
securely. Push, pull, and then
try to rotate or turn the tire.
If it moves, tighten the cable.

When It Is Time for New
Tires
Various factors, such as
maintenance, temperatures, driving
speeds, vehicle loading, and road
conditions inuence when you need
new tires.
One way to tell when it is time for
new tires is to check the treadwear
indicators, which will appear
when the tires have only 1/16 inch
(1.6 mm) or less of tread remaining.You need new tires if any of the
following statements are true:You can see the indicators at
three or more places around
the tire.
You can see cord or fabric
showing through the tire’s rubber.
The tread or sidewall is cracked,
cut, or snagged deep enough to
show cord or fabric.
The tire has a bump, bulge,
or split.
The tire has a puncture, cut, or
other damage that cannot be
repaired well because of the size
or location of the damage.
The rubber in tires degrades over
time, even if they are not being
used. This is also true for the spare
tire, if the vehicle has one. Multiple
conditions affect how fast this
aging takes place, including
temperatures, loading conditions,
and ination pressure maintenance.With proper care and maintenance
tires typically wear out before
they degrade due to age. If you are
unsure about the need to replace
the tires as they get older, consult
the tire manufacturer for more
information.
Buying New Tires
GM has developed and matched
specic 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
Specication (TPC Spec) system
rating. If you need replacement
tires, GM strongly recommends
that you get tires with the same
TPC Spec rating. 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.
5-50 Service and Appearance Care

GM’s exclusive TPC Spec
system considers over a dozen
critical specications that
impact the overall performance
of your vehicle, including
brake system performance, ride
and handling, traction control,
and tire pressure monitoring
performance. GM’s TPC Spec
number is molded onto the tire’s
sidewall near the tire size. If
the tires have an all-season
tread design, the TPC Spec
number will be followed by an
MS for mud and snow. SeeTire
Sidewall Labeling on page 5-37
for additional information.
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.SeeTire Inspection and Rotation
on page 5-48for information on
proper tire rotation.
{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. SeeCompact Spare
Tire on page 5-83.
{CAUTION
If you use bias-ply tires on the
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 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.
Vehicles that have a tire pressure
monitoring system could give an
inaccurate low-pressure warning
if non-TPC Spec rated tires are
installed on your vehicle.
Service and Appearance Care 5-51

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. SeeTire
Pressure Monitor System on
page 5-44.
Your vehicle’s original equipment
tires are listed on the Tire and
Loading Information Label.
SeeLoading the Vehicle
on page 4-16, 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, rollover airbags, 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 5-50
andAccessories and Modifications
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
5-52 Service and Appearance Care

Wheel Replacement
Replace any wheel that is bent,
cracked, or badly rusted or corroded.
If wheel nuts keep coming loose, the
wheel, wheel bolts, and wheel nuts
should be replaced. If the wheel
leaks air, replace it (except some
aluminum wheels, which can
sometimes be repaired). See your
dealer/retailer if any of these
conditions exist.
Your dealer/retailer will know the
kind of wheel you need.
Each new wheel should have the
same load-carrying capacity,
diameter, width, offset, and be
mounted the same way as the
one it replaces.If you need to replace any of your
wheels, wheel bolts, wheel nuts,
or Tire Pressure Monitor System
(TPMS) sensors, replace them only
with new GM original equipment
parts. This way, you will be sure to
have the right wheel, wheel
bolts, wheel nuts, and TPMS
sensors for your vehicle.
{CAUTION
Using the wrong replacement
wheels, wheel bolts, or wheel nuts
on your vehicle can be
dangerous. It could affect the
braking and handling of your
vehicle, make your tires lose air
and make you lose control. You
could have a collision in which
you or others could be injured.
Always use the correct wheel,
wheel bolts, and wheel nuts for
replacement.Notice:The wrong wheel can
also cause problems with bearing
life, brake cooling, speedometer
or odometer calibration,
headlamp aim, bumper height,
vehicle ground clearance, and tire
or tire chain clearance to the
body and chassis.
SeeChanging a Flat Tire on
page 5-71for more information.
Used Replacement Wheels
{CAUTION
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.
Service and Appearance Care 5-55

{CAUTION
Over-inating a tire could cause
the tire to rupture and you or
others could be injured. Be sure
to read and follow the tire sealant
and compressor kit instructions
and inate the tire to its
recommended pressure. Do not
exceed the recommended
pressure.
{CAUTION
Storing the tire sealant and
compressor kit 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 the tire sealant and
compressor kit in its original
location.
If this vehicle has a tire sealant and
compressor kit, there may not be a
spare tire, tire changing equipment,
and on some vehicles there may not
be a place to store a tire.The tire sealant and compressor
can be used to temporarily seal
punctures up to
14inch (6 mm) in the
tread area of the tire. It can also be
used to inate an under inated tire.
If the tire has been separated from
the wheel, has damaged sidewalls,
or has a large puncture, the tire
is too severely damaged for the tire
sealant and compressor kit to be
effective. SeeRoadside Assistance
Program on page 7-6.
Read and follow all of the tire
sealant and compressor kit
instructions.

Service and Appearance Care 5-61

When using the tire sealant and
compressor kit during cold
temperatures, warm the kit in a
heated environment for 5 minutes.
This will help to inate the tire faster.
Always do a safety check rst.
SeeIf a Tire Goes Flat on
page 5-56. Do not remove any
objects that have penetrated the tire.
1. Remove the tire sealant and
compressor kit from its storage
location. SeeTire Sealant
and Compressor Kit Storage on
page 5-70.
2. Unwrap the sealant/air hose (F)
and the power plug (H).
3. Place the kit on the ground.
Make sure the tire valve
stem is positioned close to the
ground so the hose will reach it.4. Remove the valve stem cap from
the at tire by turning it
counterclockwise.
5. Attach the sealant/air hose (F)
onto the tire valve stem. Turn
it clockwise until it is tight.
6. Plug the power plug (H) into the

from other accessory power
outlets. SeeAccessory Power
Outlet(s) on page 3-18.
If the vehicle has an accessory
power outlet, do not use the
cigarette lighter.
If the vehicle only has a cigarette
lighter, use the cigarette lighter.
Do not pinch the power plug
cord in the door or window.7. Start the vehicle. The vehicle
must be running while using
the air compressor.
8. Turn the selector switch (A)
counterclockwise to the Sealant +
Air position.
9. Press the on/off (B) button to
turn the tire sealant and
