Step 2. To let air-pressure out of a tire you
can use the pointed end of the valve cap,
a pencil-style air pressure gage, or a key.
6. Proceed to the passenger’s side front tire,
and repeat the procedure in Step 5.
7. Proceed to the passenger’s side rear tire,
and repeat the procedure in Step 5.
8. Proceed to the driver’s side rear tire, and
repeat the procedure in Step 5.
9. After hearing the conrming horn chirp for the
driver side rear tire, check to see if the TPMS
low tire warning light and the DIC LOW TIRE
messages have turned off. If yes, the TPMS
sensors have been relearned. Turn the ignition
switch to LOCK.
If the low tire warning light and the DIC SERV
TPM messages are on after completing Step 5
for the driver side rear tire, the sensor relearn
process has not been successful. Turn the
ignition switch to LOCK and repeat the
matching process beginning with Step 2.

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

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.
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 by the tire manufacturer.
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 378for additional information.{CAUTION:
Mixing tires could cause you to lose
control of your vehicle 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.
CAUTION: (Continued)
392

Spare Tire
Compact Spare Tire
Your vehicle may have a compact spare tire.
Although the compact spare tire was fully inated
when your vehicle was new, it can lose air
over time. Check the ination pressure regularly.
It should be 60 psi (420 kPa).
Notice:If your vehicle has four-wheel drive
and the compact spare tire is installed on
your vehicle, do not drive in four-wheel drive
until you can have your at tire repaired and/or
replaced. You could damage your vehicle,
and the repair costs would not be covered
by your warranty. Never use four-wheel drive
when the compact spare tire is installed
on your vehicle.
After installing the compact spare on your
vehicle, you should stop as soon as possible
and make sure your vehicle’s spare tire is
correctly inated. The compact spare is made to
perform well at speeds up to 62 mph (100 km/h)
for distances up to 500 miles (804 km).For heavy payloads or towing, and for low traction
or four-wheel-drive conditions, repair or replace
the full-size tire. Of course, it is best to replace
your vehicle’s spare with a full-size tire as soon
as you can. The spare tire will last longer and be
in good shape in case you need it again.
Notice:When the compact spare is installed,
do not take your vehicle through an automatic
car wash with guide rails. The compact
spare can get caught on the rails. That can
damage the tire and wheel, and maybe
other parts of your vehicle.
Do not use your compact spare on other vehicles.
And do not mix your compact spare tire or
wheel with other wheels or tires. They will not t.
Keep your spare tire and its wheel together.
Notice:Tire chains will not t your compact
spare. Using them can damage your vehicle
and can damage the chains too. Do not use
tire chains on your compact spare.
420

Full-Size Spare Tire
Your vehicle may have a full-size spare tire,
which, when new, was fully inated. A spare
tire may lose air over time, so check its ination
pressure regularly. SeeInation - Tire Pressure
on page 384andLoading Your Vehicle on
page 293for information regarding proper tire
ination and loading your vehicle. For instruction
on how to remove, install, or store a spare tire,
seeRemoving the Flat Tire and Installing the
Spare Tire on page 404andStoring a Flat
or Spare Tire and Tools on page 416.
Your vehicle may have a different size spare tire
than the road tires originally installed on your
vehicle. This spare was developed for use on
your vehicle, so it is alright to drive on it. If your
vehicle has four-wheel drive and the different
size spare tire is installed, keep the vehicle
in two-wheel drive.Notice:If your vehicle has four-wheel drive
and the different size spare tire is installed
on your vehicle, do not drive in four-wheel
drive until you can have your at tire repaired
and/or replaced. You could damage your
vehicle, and the repair costs would not
be covered by your warranty. Never use
four-wheel drive when the different size
spare tire is installed on your vehicle.
After installing the spare tire on your vehicle,
you should stop as soon as possible and make
sure the spare is correctly inated. The spare
tire is made to perform well at speeds up to
62 mph (100 km/h) for distances up to 500 miles
(804 km). For heavy payloads or towing, and
for low traction or four-wheel-drive conditions,
repair or replace the full-size tire. Have the
damaged or at road tire repaired or replaced
as soon as you can and installed back onto
your vehicle. This way, the spare tire will be
available in case you need it again.
Do not mix tires and wheels of different sizes,
because they will not t. Keep your spare tire
and its wheel together.
