When It Is Time for New Tires
Various factors, such as maintenance, temperatures,
driving speeds, vehicle loading, and road conditions
influence 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 your 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 your vehicle has one. Multiple conditions affect how
fast this aging takes place, including temperatures,
loading conditions, and inflation pressure maintenance.
With proper care and maintenance tires will typically
wear out before they degrade due to age. If you are
unsure about the need to replace your tires as they get
older, consult the tire manufacturer for more information.
Buying New Tires
GM has developed and matched specific tires for your
vehicle. If you need replacement tires, GM strongly
recommends that you get tires that are the same size,
brand, 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.
See Tire Sidewall Labeling
on page 6‑51for 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 6‑61.
{WARNING:
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 6‑78.
{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.
Vehicles that have a tire pressure monitoring system
could give an inaccurate low‐pressure warning if tires
not recommended for your vehicle are installed. Tires
that do not match the original equipment tires could give
a low‐pressure warning that is higher or lower than the
proper warning level you would get with original
equipment tires. See Tire Pressure Monitor System
on
page 6‑58.
Your vehicle's original equipment tires are listed on the
Tire and Loading Information Label. See Loading the
Vehicle
on page 5‑14, for more information about the
Tire and Loading Information label and its location on
your vehicle.

Wheel Alignment and Tire Balance
The tires and wheels on your vehicle were aligned and
balanced carefully at the factory to give you the longest
tire life and best overall performance. Adjustments to
wheel alignment and tire balancing will not be
necessary on a regular basis. However, if you notice
unusual tire wear or your vehicle pulling to one side or
the other, the alignment might need to be checked.
If you notice your vehicle vibrating when driving on a
smooth road, the tires and wheels might need to be
rebalanced. See your dealer/retailer for proper
diagnosis.
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.
{WARNING:
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.
See Changing a Flat Tire
on page 6‑70for more
information.

Storing a Flat or Spare Tire and
Tools
{WARNING:
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.
To store a flat or compact spare tire and tools: 1. Store the flat tire or the compact spare in the compact spare tire compartment.
2. Secure the retainer.
3. Store the tools securely in the foam tray and place the tray back in the cargo area.
4. Replace the trim cover.
The compact spare tire is for temporary use only.
Replace the compact spare tire with a full-size tire as
soon as you can. See Compact Spare Tire
on
page 6‑78.
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.
The compact spare tire 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
(414 kPa).
After installing the compact spare on your vehicle, you
should stop as soon as possible and make sure your
spare tire is correctly inflated. The compact spare is
intended to perform well at speeds up to 50 mph
(80 km/h), so you can finish your trip and have your
full-size tire repaired or replaced where you want.
Replace your spare with a full-size tire as soon as
you can.

Do not clean the vehicle using:
.A knife or any other sharp object to remove a soil
from any interior surface.
.A stiff brush. It can cause damage to the vehicle's
interior surfaces.
.Heavy pressure or aggressive rubbing with a
cleaning cloth. Use of heavy pressure can damage
the interior and does not improve the effectiveness
of soil removal.
.Laundry detergents or dishwashing soaps with
degreasers can leave residue that streaks and
attracts dirt. For liquid cleaners, about 20 drops per
gallon (3.78 L) of water is a good guide. Use only
mild, neutral-pH soaps.
.Too much cleaner that saturates the upholstery.
.Organic solvents such as naptha, alcohol, etc. that
can damage the vehicle's interior.
Fabric/Carpet
Use a vacuum cleaner with a soft brush attachment
frequently to remove dust and loose dirt. A canister
vacuum with a beater bar in the nozzle may only be
used on floor carpet and carpeted floor mats. For anysoil, always try to remove it first with plain water or club
soda. Before cleaning, gently remove as much of the
soil as possible using one of the following techniques:
.For liquids: gently blot the remaining soil with a
paper towel. Allow the soil to absorb into the paper
towel until no more can be removed.
.For solid dry soils: remove as much as possible
and then vacuum.
To clean: 1. Saturate a lint-free, clean white cloth with water or club soda.
2. Wring the cloth to remove excess moisture.
3. Start on the outside edge of the soil and gently rub toward the center. Continue cleaning, using a clean
area of the cloth each time it becomes soiled.
4. Continue to gently rub the soiled area until the cleaning cloth remains clean.
5. If the soil is not completely removed, use a mild soap solution and repeat the cleaning process that
was used with plain water.
If any of the soil remains, a commercial fabric cleaner or
spot lifter may be necessary. When a commercial
upholstery cleaner or spot lifter is to be used, test a
small hidden area for colorfastness first. If the locally
cleaned area gives any impression that a ring formation
may result, clean the entire surface.
