(3) Aspect Ratio:Atwo-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 tire illustration, it
would mean that the tire's
sidewall is 75 percent as high as
it is wide.
(4) Construction Code:Aletter
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.
(5) Rim Diameter:Diameter of
the wheel in inches.
(6) Service Description:These
characters represent the load
index and speed rating of the
tire. The load index represents
the load carrying capacity a tire
is certified to carry. The speed
rating is the maximum speed a
tire is certified to carry a load.

.The TPMS sensor matchingprocess was not done or notcompleted successfully afterrotating the tires. Themalfunction light and the DICmessage should go off aftersuccessfully completing thesensor matching process. See"TPMS Sensor MatchingProcess" later in this section.
.One or more TPMS sensors aremissing or damaged. Themalfunction light and the DICmessage should go off when theTPMS sensors are installed andthe sensor matching process isperformed successfully. Seeyour dealer for service.
.Replacement tires or wheels donot match the original equipmenttires or wheels. Tires and wheelsother than those recommended
could prevent the TPMS fromfunctioning properly. SeeBuyingNew Tires0415.
.Operating electronic devices orbeing near facilities using radiowave frequencies similar to theTPMS could cause the TPMSsensors to malfunction.
If the TPMS is not functioningproperly, it cannot detect or signal alow tire condition. See your dealerfor service if the TPMS malfunctionlight and DIC message come onand stay on.
TPMS Sensor Matching
Process
Each TPMS sensor has a uniqueidentification code. The identificationcode needs to be matched to a newtire/wheel position after rotating thevehicle’stiresorreplacingoneormore of the TPMS sensors. Also,the TPMS sensor matching processshould be performed after replacingasparetirewitharoadtirecontaining the TPMS sensor. Themalfunction light and the DIC
message should go off at the nextignition cycle. The sensors arematched to the tire/wheel positions,using a TPMS relearn tool, in thefollowing order: driver side front tire,passenger side front tire, passengerside rear tire, and driver side rear.See your dealer for service or topurchase a relearn tool. A TPMSrelearn tool can also be purchased.See Tire Pressure Monitor SensorActivation Tool atwww.gmtoolsandequipment.com orcall 1-800-GM TOOLS(1-800-468-6657).
There are two minutes to match thefirst tire/wheel position, andfive minutes overall to match all fourtire/wheel positions. If it takeslonger, the matching process stopsand must be restarted.
The TPMS sensor matchingprocess is:
1. Set the parking brake.
2. Turn the ignition to ON/RUNwith the engine off.

Vehicle Storage
Tires age when stored normallymounted on a parked vehicle. Parkavehiclethatwillbestoredforatleast a month in a cool, dry, cleanarea away from direct sunlight toslow aging. This area should be freeof grease, gasoline, or othersubstances that can deterioraterubber.
Parking for an extended period cancause flat spots on the tires thatmay result in vibrations whiledriving. When storing a vehicle forat least a month, remove the tires orraise the vehicle to reduce theweight 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. SeeTire Sidewall
Labeling0399for 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
time. If proper rotation and
maintenance have been done,
all four tires (six for dual rear
wheels) should wear out at
about the same time. SeeTire
Rotation0412for information
on proper tire rotation. However,
if it is necessary to replace only
one axle set of worn tires, place
the new tires on the rear axle
(two for single rear wheels, four
for dual rear wheels).
{Warning
Tires could explode during
improper service. Attempting
to mount or dismount a tire
could cause injury or death.
Only your dealer or authorized
tire service center should
mount or dismount the tires.

norm due to variations in driving
habits, service practices and
differences in road
characteristics and climate.
Traction
The traction grades, from
highest to lowest, are AA, A, B,
and C. Those grades represent
the tire's ability to stop on wet
pavement as measured under
controlled conditions on
specified government test
surfaces of asphalt and
concrete. A tire marked C may
have poor traction performance.
Warning: The traction grade
assigned to this tire is based on
straight-ahead braking traction
tests, and does not include
acceleration, cornering,
hydroplaning, or peak traction
characteristics.
Temperature
The temperature grades are A
(the highest), B, and C,
representing the tire's resistance
to the generation of heat and its
ability to dissipate heat when
tested under controlled
conditions on a specified indoor
laboratory test wheel. Sustained
high temperature can cause the
material of the tire to degenerate
and reduce tire life, and
excessive temperature can lead
to sudden tire failure. The grade

performance on the laboratory
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 alignedand balanced at the factory toprovide the longest tire life and bestoverall performance. Adjustments towheel alignment and tire balancingare not necessary on a regularbasis. Consider an alignment checkif there is unusual tire wear or thevehicle is significantly pulling to oneside or the other. Some slight pull tothe left or right, depending on thecrown of the road and/or other roadsurface variations such as troughsor ruts, is normal. If the vehicle isvibrating when driving on a smoothroad, the tires and wheels may needto be rebalanced. See your dealerfor proper diagnosis.
Wheel Replacement
Replace any wheel that is bent,cracked, or badly rusted orcorroded. If wheel nuts keep comingloose, the wheel, wheel bolts andwheel nuts should be replaced.If the wheel leaks air, replace it.
