(B) TPC Spec (Tire Performance Criteria
Specification)
:Original equipment tires designed
to GM's specific tire performance criteria have a
TPC specification code molded onto the sidewall.
GM's TPC specifications meet or exceed all
federal safety guidelines.
(C) DOT (Department of Transportation)
:
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 Identification Number (TIN)
:The letters
and numbers following DOT code are the Tire
Identification Number (TIN). The TIN shows the
manufacturer and plant code, tire size, and date
the tire was manufactured. The TIN is molded
onto both sides of the tire, although only one side
may have the date of manufacture. (E) Tire Ply Material
:The type of cord and
number of plies in the sidewall and under the
tread.
(F) Uniform Tire Quality Grading (UTQG)
:Tire
manufacturers are required to grade tires based
on three performance factors: treadwear, traction,
and temperature resistance. For more information,
see Uniform Tire Quality Grading
on page 7‑74.
(G) Maximum Cold Inflation Load Limit
:
Maximum load that can be carried and the
maximum pressure needed to support that load.
For information on recommended tire pressure
see Inflation - Tire Pressure
on page 7‑64and
Loading the Vehicle
on page 6‑32.
7-59
Reset the Tire Pressure Monitor System. SeeTire
Pressure Monitor Operation
on page 7‑67.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specifications
on page 7‑112.
{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 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.
See Changing a Flat Tire
on page 7‑79.
Make sure the spare tire is stored securely. Push,
pull, and then try to rotate or turn the tire. If it
moves, tighten the cable. See Storing a Flat or
Spare Tire and Tools
on page 7‑92.
When It Is Time for New Tires
Various factors, such as maintenance, temperatures,
driving speeds, vehicle loading, and road conditions,
influence when you need new tires.
One way to tell when it is
time for new tires is to
check the treadwear
indicators, which 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.
7-71
You need new tires 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.
The rubber in tires degrades over time, even if they are
not being used. This is also true for the spare tire,
if your vehicle has one. Multiple conditions affect how
fast this aging takes place, including temperatures,
loading conditions, and inflation pressure maintenance.
With proper care and maintenance tires will typically
wear out before they degrade due to age. If you are
unsure about the need to replace your tires as they get
older, consult the tire manufacturer for more information.
Buying New Tires
GM has developed and matched specific 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 Specification
(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 specifications 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 near the tire
size. If the tires have an all‐season tread design, the
TPC spec number will be followed by an MS for mud
and snow. See Tire Sidewall Labeling
on page 7‑58for
additional information.
GM recommends replacing tires in sets of four. This is
because uniform tread depth on all tires will help keep
your vehicle performing most like it did when the tires
were new. Replacing less than a full set of tires can
affect the braking and handling performance of your
vehicle. See Tire Inspection and Rotation
on page 7‑70for information on proper tire rotation.
7-72
{WARNING:
Never use oil or grease on bolts or nuts because
the nuts might come loose. The vehicle's wheel
could fall off, causing a crash.
9. Put the wheel nuts back on with the rounded end of the nuts toward the wheel after mounting the
spare tire.
10. Tighten each wheel nut by hand. Then use the wheel wrench to tighten the wheel nuts until the
wheel is held against the hub.
11. Turn the wheel wrench counterclockwise to lower the vehicle. Lower the jack completely.
{WARNING:
Wheel nuts that are improperly or incorrectly
tightened can cause the wheels to become loose
or come off. The wheel nuts should be tightened
with a torque wrench to the proper torque
specification after replacing. Follow the torque
specification supplied by the aftermarket

manufacturer when using accessory locking wheel
nuts. SeeCapacities and Specifications
on
page 7‑112
for original equipment wheel nut
torque specifications.
Notice: Improperly tightened wheel nuts can lead to
brake pulsation and rotor damage. To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper
torque specification. See Capacities and
Specifications
on page 7‑112for the wheel nut torque
specification.
12. Tighten the nuts firmly
in a crisscross
sequence as shown by
turning the wheel
wrench clockwise.

Vehicle Identification
Vehicle Identification Number (VIN)
This legal identifier is in the front corner of the
instrument panel, on the driver side. It can be seen
through the windshield from outside. The VIN also
appears on the Certification/Tire and Service Parts
labels and certificates of title and registration.
Engine Identification
The eighth character in the VIN is the engine code.
This code identifies the vehicle's engine, specifications,
and replacement parts. See“Engine Specifications”
under Capacities and Specifications
on page 7‑112for
the vehicle's engine code.
Service Parts Identification Label
This label, on the inside of the glove box, has the
following information:
.Vehicle Identification Number (VIN)
.Model designation
.Paint information
.Production options and special equipment
Do not remove this label from the vehicle.
Electrical System
Add-On Electrical Equipment
Notice: Do not add anything electrical to the vehicle
unless you check with your dealer/retailer first.
Some electrical equipment can damage the vehicle
and the damage would not be covered by the
vehicle's warranty. Some add-on electrical
equipment can keep other components from
working as they should.
Add-on equipment can drain the vehicle battery, even if
the vehicle is not operating.
