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.
SeeWhen It Is Time for New Tires on page 391
andWheel Replacement on page 396for
more information.
Make sure the spare tire is stored securely.
Push, pull, and then try to rotate or turn the tire.
If it moves, use the wheel wrench to tighten
the cable. SeeChanging a Flat Tire on page 400.
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 442.When rotating your tires, always use one of the
correct rotation patterns shown here.
If your vehicle has a compact spare tire or a spare
tire that does not match your vehicle’s road tires
and wheels, in size and type, do not include
the spare 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. For the
location of the Tire and Loading Information label
seeLoading Your Vehicle on page 293. Make
certain that all wheel nuts are properly tightened,
see “Wheel Nut Torque” underCapacities and
Specications on page 437for the proper wheel
nut torque specication.
390

{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 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 400.
Any time you rotate the vehicle’s tires the Tire
Pressure Monitor System (TPMS) will need to be
reset. The TPMS identication codes will need
to be matched to the tire and wheel position.
See “TPMS Sensor Identication Codes” under
Tire Pressure Monitor System on page 385.
When It Is Time for 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.
Some commercial truck
tires may not have
treadwear indicators.
You need a new tire 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.
391

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:
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 400for more
information.
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.
397

Drive slowly and follow the chain
manufacturer’s instructions. If you can hear
the chains contacting your vehicle, stop
and retighten them. If the contact continues,
slow down until it stops. Driving too fast or
spinning the wheels with chains on will
damage your vehicle.
If a Tire Goes Flat
It is unusual for a tire to blowout while you are
driving, especially if you maintain your vehicle’s
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 at tire will create a drag that
pulls the vehicle toward that side. Take your foot off
the accelerator pedal and grip the steering wheel
rmly. 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.
{CAUTION:
Lifting a vehicle and getting under it to
do maintenance or repairs is dangerous
without the appropriate safety equipment
and training. The jack provided with your
vehicle is designed only for changing a
at tire. If it is used for anything else, you
or others could be badly injured or killed
if the vehicle slips off the jack. Use the
jack provided with your vehicle only for
changing a at tire.
If a tire goes at, the next part shows how to
use the jacking equipment to change a at
tire safely.
399

Changing a Flat Tire
If a tire goes at, avoid further tire and wheel
damage by driving slowly to a level place. Turn on
your hazard warning ashers. SeeHazard Warning
Flashers on page 162for more information.
{CAUTION:
Changing a tire can be dangerous. The
vehicle can slip off the jack and roll over
or fall on you or other people. You and
they could be badly injured or even killed.
Find a level place to change your tire.
To help prevent the vehicle from moving:
1. Set the parking brake rmly.
2. Put the shift lever in PARK (P).
CAUTION: (Continued)
CAUTION: (Continued)
3. If you have a four-wheel-drive vehicle,
be sure the transfer case is in a drive
gear – not in NEUTRAL.
4. Turn off the engine and do not restart
while the vehicle is raised.
5. Do not allow passengers to remain
in the vehicle.
To be even more certain the vehicle will
not move, put blocks at the front and
rear of the tire farthest away from the
one being changed. That would be the
tire on the other side, at the opposite
end of the vehicle.

4. Tilt the retainer
when the tire has
been lowered,
and slide it up the
cable so it can
be pulled up through
the wheel opening.
5. Put the spare tire near the at tire.Removing the Flat Tire and
Installing the Spare Tire
Use the following pictures and instructions as a
guide in removing the at tire and raising the vehicle.
The tools you will be using include the jack (A),
the wheel blocks (B), the extension tool (C),
the jack handle extensions (D), and the wheel
wrench (E).
404

Secondary Latch System
Your vehicle has an underbody-mounted tire hoist
assembly that has a secondary latch system.
It is designed to stop the spare tire from suddenly
falling off your vehicle. For the secondary latch
to work, the spare must be installed with the valve
stem pointing down. SeeStoring a Flat or Spare
Tire and Tools on page 416.
{CAUTION:
Before beginning this procedure read all
the instructions. Failure to read and follow
the instructions could damage the hoist
assembly and you and others could get
hurt. Read and follow the instructions
listed next.To release the spare tire from the secondary latch:
1. Check under the
vehicle to see
if the cable end
tting is visible.
2. If the cable end tting is not visible, proceed
to Step 6.
If it is visible, rst try to tighten the cable
by turning the wheel wrench clockwise until
you hear two clicks or feel it skip twice.
You cannot overtighten the cable.
3. Loosen the cable by turning the wheel
wrench counterclockwise three or four turns.
412

13. Disconnect the jack handle from the jack and
carefully remove the jack. Use one hand to
push against the spare while rmly pulling the
jack out from under the spare tire with the
other hand.
If the spare tire is hanging from the cable,
insert the hoist end of the extension into
the hoist shaft hole in the bumper and turn
the wheel wrench counterclockwise to
lower the spare the rest of the way.
14. Tilt the tire retainer at the end of the cable
and pull it through the wheel opening.
Pull the tire out from under the vehicle.
15. If the cable is hanging under the vehicle, turn
the wheel wrench clockwise to raise the cable.
Have the hoist assembly inspected as soon
as you can. You will not be able to store
a spare or at tire using the hoist assembly
until it has been replaced.
To continue changing the at tire, seeRemoving
the Flat Tire and Installing the Spare Tire on
page 404.

Storing a Flat or Spare Tire
and Tools
{CAUTION:
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.
Notice:Storing an aluminum wheel with a
at tire under your vehicle for an extended
period of time or with the valve stem pointing
up may damage the wheel. Always stow
the wheel with the valve stem pointing down
and have the wheel/tire repaired as soon
as possible.Store the tire under the rear of the vehicle in the
spare tire carrier.
1. Put the tire on the ground at the rear of the
vehicle with the valve stem pointed down.
2. Tilt the retainer downward and through the
wheel opening. Make sure the retainer is
fully seated across the underside of the wheel.
