Tires
Your new vehicle comes with high-quality tires
made by a leading tire manufacturer. If you ever
have questions about your tire warranty and where
to obtain service, see your GM Warranty booklet for
details. For additional information refer to the tire
manufacturer’s booklet included with your vehicle.
{CAUTION:
Poorly maintained and improperly used
tires are dangerous.
Overloading your vehicle’s tires can
cause overheating as a result of too
much friction. You could have an
air-out and a serious accident. See
Loading Your Vehicle on page 238.
CAUTION: (Continued)
CAUTION: (Continued)

Underinated tires pose the same
danger as overloaded tires. The
resulting accident could cause serious
injury. Check all tires frequently to
maintain the recommended pressure.
Tire pressure should be checked when
your vehicle’s tires are cold. See
Inflation - Tire Pressure on page 322.
Overinated tires are more likely to be
cut, punctured, or broken by a sudden
impact — such as when you hit a
pothole. Keep tires at the
recommended pressure.
Worn, old tires can cause accidents. If
the tire’s tread is badly worn, or if
your vehicle’s tires have been
damaged, replace them.
321

Ination - Tire Pressure
The Certification or Tire Information label shows
the correct inflation pressures for your tires
when they are cold. Cold means your vehicle has
been sitting for at least three hours or driven
no more than 1 mile (1.6 km).
Notice:Do not let anyone tell you that
under-ination or over-ination is all right. It is
not. If your tires do not have enough air
(under-ination), you can get the following:
Too much exing
Too much heat
Tire overloading
Premature or irregular wear
Poor handling
Reduced fuel economy
If your tires have too much air (over-ination),
you can get the following:
Unusual wear
Poor handling
Rough ride
Needless damage from road hazards
When to Check
Check your tires once a month or more.
Also, check the tire pressure of the spare tire if
your vehicle has one.
How to Check
Use a good quality pocket-type gage to check tire
pressure. You cannot tell if your vehicle’s tires
are properly inflated simply by looking at
them. Radial tires may look properly inflated even
when they are underinflated.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out dirt
and moisture.
322

Wheel Loading
Wheels are stamped with a maximum load and
cold inflation rating. Be sure you do not exceed
these limits. If you ever think you need to exceed
these limits, first contact the rim and wheel
maker to get their advice.
Dual Tire Operation
When the vehicle is new, check the wheel nut
tightness on all wheels with a torque wrench after
your first 100 miles (160 km) and then 1,000 miles
(1 600 km) after that. Whenever a wheel, wheel
bolt or wheel nut is removed or serviced,
repeat the 100 miles (160 km), and then 1,000 mile
(1 600 km) wheel nut tightness check.SeeTightening the Wheel Nuts on page 325for
wheel nut tightening information and proper
torque values.
{CAUTION:
If you operate your vehicle with a tire that
is badly underinated, the tire can
overheat. An overheated tire can lose air
suddenly or catch re. You or others could
be injured. Be sure all tires (including the
spare, if any) are properly inated.
SeeTires on page 321andInation - Tire
Pressure on page 322for more information on
proper tire inflation.
323

When It Is Time for New Tires
Replace your tires when the tread depth is down
to 1/8 of an inch (3.2 mm) for the front tires,
or 1/16 of an inch (1.6 mm) for a rear tire. Also,
you need a new tire if:
•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.
{CAUTION:
Mixing tires could cause you to lose
control while driving. If you mix tires of
different types — like radial and
bias-belted tires — the vehicle may not
handle properly, and you could have a
crash. Be sure to use the same type of
tires all around.When you replace tires, make sure they are the
same size, load range, speed rating and
construction type (bias, bias-belted or radial) as
your original tires.
If your vehicle has four-wheel drive, the axle
differentials, propshafts and transfer case may be
damaged if tires of different sizes, brands or
tread types are installed on the front and rear
axles. That damage would not be covered under
your warranty.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned at
the factory to give you the longest tire life and
best overall performance.
Proper front wheel alignment must be maintained
in order to ensure efficient steering, good
directional stability, and prevent abnormal tire
wear. If you notice unusual tire wear or your
vehicle is pulling one way or the other, the
alignment may need to be reset. If you notice your
vehicle vibrating when driving on a smooth
road, your wheels may need to be balanced.
324

How Often to Check
Wheel tightness is so important you should have a
technician check nut tightness on all wheels with a
torque wrench after your first 100 miles (160 km),
and then 1,000 miles (1 600 km) after that. Be sure
to repeat this service whenever you have a tire
removed or serviced. SeeScheduled Maintenance
on page 363for further information.
Wheel Replacement
Replace any wheel that is bent, cracked or badly
rusted or corroded. If wheel nuts keep coming
loose, replace the wheel. If the wheel leaks
air, replace it.
Your dealer 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 or wheel nuts, replace them only with
new GM original equipment parts. This way, you
will be sure to have the right wheel, wheel
bolts and wheel nuts for your vehicle.
{CAUTION:
A leaking wheel could fail without warning.
A wheel designed for tubeless tires could
be leaking because it is damaged. Do not
use an inner tube or some other thing to try
to stop the leaking. Get a new wheel of the
proper type.
328

{CAUTION:
Without the correct wheel, you may not be
able to stop properly, and you could have
other problems like a tire air-out. You
could have a collision. If you do not go to
your dealer to get a new wheel, be sure
you get the correct one. Each new wheel
should match the original wheel in
load-carrying capacity, ination pressure
capacity, diameter, width, offset and
mounting conguration.
Using wheels and tires with higher load-carrying
limits than the original wheels and tires does
not change the Gross Axle Weight Rating (GAWR)
or the Gross Vehicle Weight Rating (GVWR) of
your vehicle. SeeLoading Your Vehicle on
page 238for more information.Notice:The wrong wheel can cause trouble in
bearing life, brake cooling,
speedometer/odometer calibration, headlamp
aim, bumper height, vehicle ground clearance,
stopping distance and tire clearance to the
body and chassis. You could also have other
problems like a tire air-out.
Used Replacement Wheels
{CAUTION:
Putting a used wheel on your 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.
329

If a Tire Goes Flat
It is unusual for a tire to blowout while you are
driving, especially if you maintain your tires
properly. If air goes out of a tire, it is much more
likely to leak out slowly. But if you should ever
have a blowout, here are a few tips about what to
expect and what to do:
If a front tire fails, the flat tire will create a drag
that pulls the vehicle toward that side. Take your
foot off the accelerator pedal and grip the
steering wheel firmly. Steer to maintain lane
position, and then gently brake to a stop well out
of the traffic lane.
A rear blowout, particularly on a curve, acts much
like a skid and may require the same correction
you would use in a skid. In any rear blowout,
remove your foot from the accelerator pedal. Get
the vehicle under control by steering the way
you want the vehicle to go. It may be very bumpy
and noisy, but you can still steer. Gently brake
to a stop –– well off the road if possible.If a tire goes flat, avoid further tire and wheel
damage by driving slowly to a level place and turn
on your hazard warning flashers. SeeHazard
Warning Flashers on page 142.
{CAUTION:
Your vehicle, when new, did not include
tire changing equipment or a place to
store a tire in the vehicle. Special tools
and procedures are required if a tire
needs to be serviced. If these tools and
procedures are not used, you or others
could be injured or killed while trying to
change or service a truck tire.

Aluminum or Chrome-Plated Wheels
The vehicle may be equipped with either
aluminum or chrome-plated wheels.
Keep the wheels clean using a soft clean cloth
with mild soap and water. Rinse with clean water.
After rinsing thoroughly, dry with a soft clean
towel. A wax may then be applied.
Notice:If you use strong soaps, chemicals,
abrasive polishes, cleaners, brushes, or
cleaners that contain acid on aluminum or
chrome-plated wheels, you could damage the
surface of the wheel(s). The repairs would
not be covered by your warranty. Use
only GM-approved cleaners on aluminum or
chrome-plated wheels.
The surface of these wheels is similar to the
painted surface of your vehicle. Do not use strong
soaps, chemicals, abrasive polishes, abrasive
cleaners, cleaners with acid, or abrasive cleaning
brushes on them because you could damage
the surface. Do not use chrome polish on
aluminum wheels.Notice:Using chrome polish on aluminum
wheels could damage the wheels. The repairs
would not be covered by your warranty.
Use chrome polish on chrome wheels only.
Use chrome polish only on chrome-plated wheels,
but avoid any painted surface of the wheel, and
buff off immediately after application.
Tires
To clean the tires, use a stiff brush with tire cleaner.
Notice:Using petroleum-based tire dressing
products on your vehicle may damage the
paint nish and/or tires. When applying a tire
dressing, always wipe off any overspray
from all painted surfaces on your vehicle.
Sheet Metal Damage
If the vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair
shop applies anti-corrosion material to parts
repaired or replaced to restore corrosion protection.
Original manufacturer replacement parts will
provide the corrosion protection while maintaining
the warranty.
