Tire Size
The following examples show the different parts of a
tire size.
(A) Passenger (P-Metric) Tire:The United States
version of a metric tire sizing system. The letter P as
the rst character in the tire size means a passenger
vehicle tire engineered to standards set by the U.S. Tire
and Rim Association.(A) Light Truck (LT-Metric) Tire:The United States
version of a metric tire sizing system. The letters LT as
the rst two characters in the tire size means a light
truck tire engineered to standards set by the U.S. Tire
and Rim Association.
(B) Tire Width:The three-digit number indicates the
tire section width in millimeters from sidewall to sidewall.
(C) Aspect Ratio:A two-digit number that indicates
the tire height-to-width measurements. For example, if
the tire size aspect ratio is 75, as shown in item C of the
light truck (LT-Metric) tire illustration, it would mean
that the tire’s sidewall is 75% as high as it is wide.
(D) Construction Code:A letter code is used to
indicate the type of ply construction in the tire. The
letter R means radial ply construction; the letter D means
diagonal or bias ply construction; and the letter B means
belted-bias ply construction.
(E) Rim Diameter:Diameter of the wheel in inches.
(F) Service Description:The service description
indicates the load range and speed rating of a tire.
The load index can range from 1 to 279. Speed ratings
range from A to Z. Passenger (P-Metric) Tire
Light Truck (LT-Metric) Tire

The Tire and Loading Information label (tire information
placard) shows the size of your vehicle’s original
tires and the correct ination pressure for your vehicle’s
tires when they are cold. SeeInation - Tire Pressure
on page 5-65. For the location of the tire and loading
information label, seeLoading Your Vehicle on
page 4-48.
Your vehicle’s TPMS can alert you about a low tire
pressure condition but it does not replace normal tire
maintenance. SeeTire Inspection and Rotation on
page 5-70andTires on page 5-59.
Notice:Do not use a tire sealant if your vehicle
has Tire Pressure Monitors. The liquid sealant can
damage the tire pressure monitor sensors.
Resetting the TPMS Identication Codes
Each TPMS sensor has a unique identication code.
Any time you rotate your vehicle’s tires or replace one or
more of the TPMS sensors, the identication codes
will need to be matched to the new tire/wheel position.
Each tire/wheel position is matched to a sensor, by
increasing or decreasing the tire’s air pressure.
The sensors are matched to the tire/wheel positions in
the following order: LF TIRE (left front tire on the
driver’s side of the vehicle), RF TIRE (right front tire on
the passengers side of the vehicle), RR TIRE (right
rear tire on the passengers side of the vehicle), and
LR TIRE (left rear tire on the driver’s side of the vehicle).You will have one minute to match the rst tire/wheel
position, and ve minutes overall to match all four tire/
wheel positions. If it takes longer than one minute, to
match the rst tire and wheel, or more than ve minutes
to match all four tire and wheel positions the matching
process stops and you will need to start over.
The TPMS sensor matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to RUN with the engine off.
3. Turn the headlamp switch from off to the parking
lamps setting four times within three seconds. A
double horn chirp will sound and the TPMS low tire
warning light will begin to ash. The double horn
chirp and ashing TPMS warning light indicate that
the TPMS matching process has started. The
TPMS warning light should continue ashing
throughout the matching procedure. The SERVICE
TIRE MONITOR message will be displayed on
the Driver Information Center (DIC).
4. Start with the driver’s side front tire.
5-68

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 5-66.
Make certain that all wheel nuts are properly tightened.
See “Wheel Nut Torque” underCapacities and
Specications on page 5-118.
{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 5-79.
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.
5-71

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 5-60for additional information.{CAUTION:
Mixing tires could cause you to lose control
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 same size,
brand, and type tires on all wheels.
Your vehicle may have a different size spare
than the road tires (those originally installed
on your vehicle). When new, your vehicle
included a spare tire and wheel assembly with
a similar overall diameter as your vehicle’s
road tires and wheels, so it is all right to drive
on it. Because this spare was developed for
use on your vehicle, it will not affect vehicle
handling.
5-72

{CAUTION:
If you use bias-ply tires on your vehicle, the
wheel rim anges could develop cracks after
many miles of driving. A tire and/or wheel
could fail suddenly, causing a crash. Use only
radial-ply tires with the wheels on your vehicle.
If you must replace your vehicle’s tires with those that
do not have a TPC Spec number, make sure they
are the same size, load range, speed rating, and
construction type (radial and bias-belted tires) as your
vehicle’s original tires.
Vehicles that have a tire pressure monitoring system
may give an inaccurate low-pressure warning if non-TPC
spec rated tires are installed on your vehicle. Non-TPC
Spec rated tires may give a low-pressure warning
that is higher or lower than the proper warning level
you would get with TPC Spec rated tires. SeeTire
Pressure Monitor System on page 5-66.
Your vehicle’s original equipment tires are listed on
the Tire and Loading Information Label. This label
is attached to the vehicle’s center pillar (B-pillar). See
Loading Your Vehicle on page 4-48, for more information
about the Tire and Loading Information Label and its
location on your vehicle.
Different Size Tires and Wheels
If you add wheels or tires that are a different size than
your original equipment wheels and tires, this may
affect the way your vehicle performs, including its
braking, ride and handling characteristics, stability,
and resistance to rollover. Additionally, if your vehicle
has electronic systems such as, anti-lock brakes,
traction control, and electronic stability control, the
performance of these systems can be affected.
{CAUTION:
If you add different sized wheels, your
vehicle may not provide an acceptable level
of performance and safety if tires not
recommended for those wheels are selected.
You may increase the chance that you will
crash and suffer serious injury. Only use
GM specic wheel and tire systems developed
for your vehicle, and have them properly
installed by a GM certied technician.
SeeBuying New Tires on page 5-72andAccessories
and Modications on page 5-3for additional information.
5-73

Tire Chains
{CAUTION:
If your vehicle has P265/75R16, LT265/75R16,
P265/70R16, P265/70R17, or P275/55R20 size
tires, do not use tire chains. They can damage
your vehicle because there is not enough
clearance. Tire chains used on a vehicle
without the proper amount of clearance can
cause damage to the brakes, suspension, or
other vehicle parts. The area damaged by the
tire chains could cause you to lose control of
your vehicle and you or others may be injured
in a crash.
Use another type of traction device only if its
manufacturer recommends it for use on your
vehicle and tire size combination and road
conditions. Follow that manufacturer’s
CAUTION: (Continued)
CAUTION: (Continued)
instructions. To help avoid damage to your
vehicle, drive slowly, readjust or remove
the device if it is contacting your vehicle,
and do not spin your vehicle’s wheels.
If you do nd traction devices that will t,
install them on the rear tires.
Notice:If you have a tire size other than
P265/75R16, LT265/75R16, P265/70R16, P265/70R17,
or P275/55R20 use tire chains only where legal
and only when you must. Use chains that are the
proper size for your tires. Install them on the
rear tires only.
Do not use chains on the front tires.
Tighten them as tightly as possible with the ends
securely fastened. 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.
5-77

Spare Tire
Your vehicle, when new, had a fully-inated spare tire.
A spare tire may lose air over time, so check its
ination pressure regularly. SeeInation - Tire Pressure
on page 5-65andLoading Your Vehicle on page 4-48
for 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 5-84andStoring
a Flat or Spare Tire and Tools on page 5-94.
Your vehicle may have a different size spare tire than
the road tires originally installed on your vehicle.
This spare tire was developed for use on your vehicle,
so it is all right 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
tire is correctly inated. 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. If your vehicle has a spare tire that does not
match your vehicle’s original road tires and wheels
in size and type, do not include the spare in the
tire rotation.
Appearance Care
Cleaning the Inside of Your Vehicle
Your vehicle’s interior will continue to look its best if
it is cleaned often. Although not always visible, dust
and dirt can accumulate on your upholstery. Dirt
can damage carpet, fabric, leather, and plastic surfaces.
Regular vacuuming is recommended to remove
particles from your upholstery. It is important to keep
your upholstery from becoming and remaining heavily
soiled. Soils should be removed as quickly as possible.
Your vehicle’s interior may experience extremes of
heat that could cause stains to set rapidly.
