buttons, tire pressure levels can be
viewed. For additional information
and details about the DIC operation
and displays, seeDriver Information
Center (DIC) on page 5-24 andTire
Messages on page 5-35.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
could be an early indicator that the
air pressure is getting low and
needs to be inflated to the proper
pressure.
A Tire and Loading Information label
shows the size of the original
equipment tires and the correct
inflation pressure for the tires when
they are cold. See Vehicle Load
Limits on page 9-9, for an example
of the Tire and Loading Information
label and its location. Also see Tire
Pressure on page 10-51. The TPMS can warn about a low
tire pressure condition but it does
not replace normal tire
maintenance. See
Tire Inspection
on page 10-56, Tire Rotation on
page 10-57 andTires on
page 10-42.
{Caution
Tire sealant materials are not all
the same. A non-approved tire
sealant could damage the TPMS
sensors. TPMS sensor damage
caused by using an incorrect tire
sealant is not covered by the
vehicle warranty. Always use only
the GM approved tire sealant
available through your dealer or
included in the vehicle.
TPMS Malfunction Light and
Message
The TPMS will not function properly
if one or more of the TPMS sensors
are missing or inoperable. When the
system detects a malfunction, the
low tire pressure warning light
flashes for about one minute and
then stays on for the remainder of
the ignition cycle. A DIC warning
message also displays. The
malfunction light and DIC warning
message come on at each ignition
cycle until the problem is corrected.
Some of the conditions that can
cause these to come on are:
.One of the road tires has been
replaced with the spare tire. The
spare tire does not have a
TPMS sensor. The malfunction
light and the DIC message
should go off after the road tire
is replaced and the sensor
matching process is performed
successfully. See "TPMS Sensor
Matching Process" later in this
section.

Vehicle Care 10-57
.The tire has a puncture, cut,
or other damage that cannot
be repaired well because of
the size or location of the
damage.
Tire Rotation
Tires should be rotated every
12 000 km (7,500 mi). See
Maintenance Schedule on
page 11-3.
Tires are rotated to achieve a
uniform wear for all tires. The
first rotation is the most
important.
Any time unusual wear is
noticed, rotate the tires as soon
as possible and check the wheel
alignment. Also check for
damaged tires or wheels. See
When It Is Time for New Tires
on page 10-58andWheel
Replacement on page 10-63.
Use this rotation pattern when
rotating the tires.
If the vehicle has a compact
spare tire, do not include it in the
tire rotation.
Adjust the front and rear tires to
the recommended inflation
pressure on the Tire and
Loading Information label after
the tires have been rotated. See
Tire Pressure on page 10-51
and Vehicle Load Limits on
page 9-9. Reset the Tire Pressure Monitor
System. See
Tire Pressure
Monitor Operation on
page 10-53.
Check that all wheel nuts are
properly tightened. See “Wheel
Nut Torque” underCapacities
and Specifications on
page 12-2.
{Warning
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
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, a cloth or a paper
towel can be used; however, use
a scraper or wire brush later to
remove all rust or dirt.

10-58 Vehicle Care
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change or
tire rotation to prevent corrosion
or rust build-up. Do not get
grease on the flat wheel
mounting surface or on the
wheel nuts or bolts.
Dual Tire Rotation
When the vehicle is new,
or whenever a wheel, wheel bolt,
or wheel nut is replaced, check the
wheel nut torque after
160, 1 600, and 10 000 km (100,
1,000, and 6,000 mi) of driving. For
proper wheel nut tightening
information, see“Removing the Flat
Tire and Installing the Spare Tire”
under Tire Changing on page 10-66.
Also see “Wheel Nut Torque” under
Capacities and Specifications on
page 12-2.
The outer tire on a dual wheel setup
generally wears faster than the
inner tire. Tires last longer and wear
more evenly if they are rotated. See
Tire Inspection on page 10-56
and Tire Rotation on page 10-57.
Also see Maintenance Schedule on
page 11-3.
{Warning
If the vehicle is operated with a
tire that is underinflated, the tire
can overheat. An overheated tire
can lose air suddenly or catch
fire. You or others could be
injured. Properly inflate all tires,
including the spare.
See Tires on page 10-42 andTire
Pressure on page 10-51 for more
information on proper tire inflation.
When It Is Time for New
Tires
Factors such as maintenance,
temperatures, driving speeds,
vehicle loading, and road conditions
affect the wear rate of the tires.
Treadwear indicators are one way to
tell when it is time for new tires.
Treadwear indicators appear when
the tires have only 1.6 mm (1/16 in)
or less of tread remaining.
Some commercial truck tires,
including Goodyear LT225/75R16
G949 RSA and Goodyear LT225/
75R16 G933 RSD, may not have
treadwear indicators. If the tires do
not have treadwear indicators,
replace the tires when the tread
depth is down to 3.2 mm (1/8 in) for
the front tires, or 1.6 mm (1/16 in) for
the rear tires.

SeeTire Inspection on page 10-56
and Tire Rotation on page 10-57 for
additional information.
The rubber in tires ages over time.
This also applies to the spare tire,
if the vehicle has one, even if it is
never used. Multiple factors
including temperatures, loading
conditions, and inflation pressure
maintenance affect how fast aging
takes place. GM recommends that
tires, including the spare if
equipped, be replaced after six
years, regardless of tread wear. The
tire manufacture date is the last four
digits of the DOT Tire Identification
Number (TIN) which is molded into
one side of the tire sidewall. The
first two digits represent the week
(01-52) and the last two digits, the
year. For example, the third week of
the year 2010 would have a
four-digit DOT date of 0310.
Vehicle Storage
Tires age when stored normally
mounted on a parked vehicle. Park
a vehicle that will be stored for at least a month in a cool, dry, clean
area away from direct sunlight to
slow aging. This area should be free
of grease, gasoline or other
substances that can deteriorate
rubber.
Parking for an extended period can
cause flat spots on the tires that
may result in vibrations while
driving. When storing a vehicle for
at least a month, remove the tires or
raise the vehicle to reduce the
weight from the tires.
Buying New Tires
GM has developed and matched
specific tires for the vehicle. The
original equipment tires installed
were designed to meet General
Motors Tire Performance Criteria
Specification (TPC Spec)
system rating. When
replacement tires are needed,
GM strongly recommends
buying tires with the same TPC
Spec rating.
GM's exclusive TPC Spec
system considers over a dozen
critical specifications that impact
the overall performance of the
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 near the tire size. If the
tires have an all-season tread
design, the TPC Spec number
will be followed by MS for mud
and snow. See
Tire Sidewall
Labeling on page 10-44 for
additional information.
GM recommends replacing worn
tires in complete sets of four (six
for dual rear wheels). Uniform
tread depth on all tires will help
to maintain the performance of
the vehicle. Braking and
handling performance may be
adversely affected if all the tires
are not replaced at the same

test wheel than the minimum
required by law. Warning: The
temperature grade for this tire is
established for a tire that is
properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive
loading, either separately or in
combination, can cause heat
buildup and possible tire failure.
Wheel Alignment and Tire
Balance
The tires and wheels were aligned
and balanced at the factory to
provide the longest tire life and best
overall performance. Adjustments to
wheel alignment and tire balancing
are not necessary on a regular
basis. Consider an alignment check
if there is unusual tire wear or the
vehicle is significantly pulling to one
side or the other. Some slight pull to
the left or right, depending on the
crown of the road and/or other road
surface variations such as troughs
or ruts, is normal. If the vehicle isvibrating when driving on a smooth
road, the tires and wheels may need
to be rebalanced. See your dealer
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.
Some aluminum wheels can be
repaired. See your dealer if any of
these conditions exist.
Your dealer will know the kind of
wheel that is needed.
Each new wheel should have the
same load-carrying capacity,
diameter, width, offset, and be
mounted the same way as the one it
replaces.
Replace wheels, wheel bolts, wheel
nuts, or Tire Pressure Monitor
System (TPMS) sensors with new
GM original equipment parts.
{Warning
Using the wrong replacement
wheels, wheel bolts, or wheel
nuts can be dangerous. It could
affect the braking and handling of
the vehicle. Tires can lose air,
and cause loss of control, causing
a crash. Always use the correct
wheel, wheel bolts, and wheel
nuts for replacement.
{Caution
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.

6. Turn the wheel wrenchclockwise to fully raise the tire
against the underside of the
vehicle. Continue turning the
wheel wrench until the tire is
secure and the cable is tight.
Two clicks should occur. The
spare tire hoist cannot be
overtightened.7. Make sure the tire is storedsecurely. Push, pull (1), and then
try to turn (2) the tire. If the tire
moves, use the wheel wrench to
tighten the cable.
Two clicks mean the tire is up all
the way.
8. Return the jacking equipment to the proper location. Secure the
items and replace the jack cover.
Full-Size Spare Tire
If this vehicle came with a full-size
spare tire, it was fully inflated when
new, however, it can lose air over
time. Check the inflation pressure
regularly. See Tire Pressure on
page 10-51 andVehicle Load Limits
on page 9-9. For instructions on
how to remove, install, or store a
spare tire, see Tire Changing on
page 10-66.
After installing the spare tire on the
vehicle, stop as soon as possible
and check that the spare is correctly
inflated. The spare tire is made to
perform well at speeds up to 112 km/h (70 mph) at the
recommended inflation pressure, so
you can finish your trip.
Have the damaged or flat road tire
repaired or replaced back onto the
vehicle, as soon as possible, so the
spare tire will be available in case it
is needed again.
Do not mix tires and wheels of
different sizes, because they will not
fit. Keep the spare tire and its wheel
together.
