With the driver’s door open, you will nd the
label attached below the door lock post (striker).
The tire and loading information label shows
the number of occupant seating positions (A),
and the maximum vehicle capacity weight (B) in
kilograms and pounds.The Tire and Loading Information label also shows
the size of the original equipment tires (C) and
the recommended cold tire in ation pressures (D).

sidewall. The following illustrations are examples
of a typical P-Metric and a LT-Metric tire sidewall.(A) Tire Size:The tire size code is a combination
of letters and numbers used to de ne a particular
tire’s width, height, aspect ratio, construction
type, and service description. See the “Tire Size”
illustration later in this section for more detail.
(B) TPC Spec (Tire Performance Criteria
Speci cation):Original equipment tires designed
to GM’s speci c tire performance criteria have
a TPC speci cation code molded onto the sidewall.
GM’s TPC speci cations meet or exceed all
federal safety guidelines.

The Department of Transportation (DOT) code
indicates that the tire is in compliance with the U.S.
Department of Transportation Motor Vehicle Safety
Standards.
(D) Tire Identi cation Number (TIN):The letters
and numbers following DOT code are the Tire
Identi cation Number (TIN). The TIN shows
the manufacturer and plant code, tire size, and

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 percent 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.

Radial Ply Tire:A pneumatic tire in which the
ply cords that extend to the beads are laid
at 90 degrees to the centerline of the tread.
Rim:A metal support for a tire and upon which
the tire beads are seated.
Sidewall:The portion of a tire between the tread
and the bead.
Speed Rating:An alphanumeric code assigned
to a tire indicating the maximum speed at
which a tire can operate.
Traction:The friction between the tire and the
road surface. The amount of grip provided.
Tread:The portion of a tire that comes into
contact with the road.
Treadwear Indicators:Narrow bands, sometimes
called wear bars, that show across the tread of a
tire when only 1/16 inch (1.6 mm) of tread remains.
SeeWhen It Is Time for New Tires on page 397.UTQGS (Uniform Tire Quality Grading
Standards):A tire information system that
provides consumers with ratings for a tire’s
traction, temperature, and treadwear. Ratings
are determined by tire manufacturers using
government testing procedures. The ratings are
molded into the sidewall of the tire. SeeUniform
Tire Quality Grading on page 400.
Vehicle Capacity Weight:The number of
designated seating positions multiplied by
150 lbs (68 kg) plus the rated cargo load.
SeeLoading Your Vehicle on page 296.
Vehicle Maximum Load on the Tire:Load on
an individual tire due to curb weight, accessory
weight, occupant weight, and cargo weight.
Vehicle Placard:A label permanently attached
to a vehicle showing the vehicle’s capacity
weight and the original equipment tire size and
recommended in ation pressure. See “Tire
and Loading Information Label” underLoading
Your Vehicle on page 296.

High-Speed Operation
{CAUTION:
Driving at high speeds, 100 mph (160 km/h)
or higher, puts an additional strain on tires.
Sustained high-speed driving causes
excessive heat build up and can cause
sudden tire failure. You could have a
crash and you or others could be killed.
Some high-speed rated tires require
in ation pressure adjustment for high
speed operation. When speed limits and
road conditions are such that a vehicle
can be driven at high speeds, make sure
the tires are rated for high speed operation,
in excellent condition, and set to the
correct cold tire in ation pressure for the
vehicle load.
If your vehicle has P255/55R18 104H size tires
installed on the rear axle, they will require
in ation pressure adjustment when driving your
vehicle at speeds above 99 mph (160 km/h).Set the cold in ation pressure, for the rear tires
only, to the maximum in ation pressure shown on
the tire sidewall, or 36 psi (248 kPa), whichever
is lower. See the example following. When you end
this high-speed driving, return the tires to the
cold tire in ation pressure shown on the Tire and
Loading Information label. SeeLoading Your
Vehicle on page 296.
Example:
You will nd the maximum load and in ation
pressure molded on the tire’s sidewall, in small
letters, near the rim ange. It will read something
like this: Maximum load 690 kg (1521 lbs)
300 kPa (44 psi) Max. Press.
For this example, you would set the in ation
pressure for high-speed driving at
36 psi (248 kPa).
The in ation pressure for the front tires should be
set to the cold tire in ation pressure shown on
the Tire and Loading Information label.
Racing or other competitive driving may affect the
warranty coverage of your vehicle. See your
warranty booklet for more information.

Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses
radio and sensor technology to check tire pressure
levels. TPMS sensors are mounted on each tire
and wheel assembly, except the spare tire.
The TPMS sensors monitor the air pressure in
your vehicle’s tires and transmit tire pressure
readings to a receiver located in the vehicle.
The TPMS is designed to alert the driver if a low
tire pressure condition exists. Tire pressure
levels may also be checked by using the Driver
Information Center (DIC) Trip Information
button, located on the instrument panel. See “Tire
Pressures” underDIC Operation and Displays
on page 195for additional information.
When a low tire pressure condition is detected,
the TPMS will illuminate the low tire pressure
warning symbol located on the instrument panel
cluster, and at the same time a message will also
appear on the DIC display. The low tire pressure
warning symbol on the instrument panel cluster
and the CHECK TIRE PRESSURE warning
message on the DIC will appear at each ignitioncycle until the tires are in ated to the correct
in ation pressure. For additional information and
details about the DIC operation and displays
seeDIC Operation and Displays on page 195and
DIC Warnings and Messages on page 199.
You may notice, during cooler weather conditions,
that the tire pressure monitor light, located on
the instrument panel cluster, and the CHECK TIRE
PRESSURE message will appear when the
vehicle is rst started, and then turn off as you
start to drive the vehicle. This could be an
early indicator that the tire pressures are getting
low and need to be in ated to the proper pressure.
Each tire, including the spare (if provided),
should be checked monthly when cold and in ated
to the in ation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire
in ation pressure label. (If your vehicle has tires
of a different size than the size indicated on
the vehicle placard or tire in ation pressure label,
you should determine the proper tire in ation
pressure for those tires.)
