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 497
andWheel Replacement on page 503for
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 ratchet/wheel wrench to tighten
the cable. SeeChanging a Flat Tire on page 506.
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 551.When rotating your vehicle’s tires, always use the
correct rotation pattern shown here.
Do not include the spare tire 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. SeeLoading
Your Vehicle on page 392andInation - Tire
Pressure on page 488, for more information.
496

Vehicles that have the Tire Pressure Monitor
System (TPMS) will need to have the TPMS
sensors reset after a tire rotation. See “TPMS
Sensor Identication Codes” underTire Pressure
Monitor System on page 490.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specications on page 546.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a 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 506.
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.
497

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 if any of these conditions exist.
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:
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 506for more
information.

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.
505

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 vehicle’s hazard warning ashers.
SeeHazard Warning Flashers on page 192
for 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).
3. Turn off the engine and do not restart
while the vehicle is raised.
4. Do not allow passengers to remain
in the vehicle.
To be even more certain the vehicle will
not move, you should 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.
506

Removing the Flat Tire and
Installing the Spare Tire
Use the following pictures and instructions to
remove the at tire and raise the vehicle.
1. Remove the center cap by placing the chisel
end of the wheel wrench in the slot on the
wheel and gently pry the cap out.2. Use the wheel wrench to loosen all the wheel
nuts. Turn the wheel wrench counterclockwise
to loosen the wheel nuts. Do not remove
the wheel nuts yet.
512

{CAUTION:
Raising your vehicle with the jack
improperly positioned can damage the
vehicle and even make the vehicle fall.
To help avoid personal injury and vehicle
damage, be sure to t the jack lift head
into the proper location before raising
the vehicle.
3. Position the jack under the vehicle as shown.
Front Tire Flat:If the at tire is on a front
tire of the vehicle, you will need to use the
jack handle (B) and only one jack handle
extension (C). Attach the wheel wrench (D) to
the jack handle extension (C). Attach the
jack handle (B) to the jack (A). Position the jack
on the frame behind the at tire where the
frame sections overlap (E). Turn the wheel
wrench (D) clockwise to raise the vehicle.
Front Position
514

Raise the vehicle far enough off the ground
so there is enough room for the spare
tire to clear the ground.
Rear Tire Flat:If the at tire is on a rear tire
of the vehicle, you will need to use the
jack handle (B) and both jack handle
extensions (C). Attach the wheel wrench (D)
to the jack handle extensions (C). Attach
the jack handle (B) to the jack (A).Use the jacking pad provided on the rear axle.
Turn the wheel wrench (D) clockwise to
raise the vehicle. Raise the vehicle far enough
off the ground so there is enough room for
the spare tire to clear the ground.
4. Remove all of the
wheel nuts.
5. Take off the at tire.

Secondary Latch System
Your vehicle has an underbody-mounted tire hoist
assembly which 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 tire must be installed with
the valve stem pointing down. SeeStoring a Flat
or Spare Tire and Tools on page 522.
{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,
do the following:
1. Check under the
vehicle to see if
the cable end
is visible. If the cable
is not visible,
proceed to Step 6.
2. 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.
