Tires
Your new vehicle comes with high-quality tires
made by a leading tire manufacturer. If you ever
have questions about your tire warranty and where
to obtain service, see your vehicle Warranty booklet
for details. For additional information refer to the tire
manufacturer.
{WARNING:
•Poorly maintained and improperly used
tires are dangerous.
•Overloading your tires can cause
overheating as a result of too much
flexing. You could have an air-out and
a serious accident. SeeLoading the
Vehicle on page 5-18.
WARNING: (Continued)
WARNING: (Continued)

Underinflated tires pose the same danger
as overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be
checked when your tires are cold. See
Ination - Tire Pressure on page 6-64.
•Overinflated tires are more likely to be
cut, punctured, or broken by a sudden
impact — such as when you hit a pothole.
Keep tires at the recommended pressure.
•Worn, old tires can cause accidents.
If your tread is badly worn, or if your tires
have been damaged, replace them.
SeeHigh-Speed Operation on page 6-66for
inflation pressure adjustment for high speed
driving.

Low-Prole Performance Tire
If your vehicle has P225/50R18 or P225/50R17 size
tires, they are classified as low-profile performance
tires. These tires are designed for very responsive
driving on wet or dry pavement. You may also
notice more road noise with low-profile performance
tires and that they tend to wear faster.
Notice:If the vehicle has low-prole tires,
they are more susceptible to damage from
road hazards or curb impact than standard
prole tires. Tire and/or wheel assembly
damage can occur when coming into contact
with road hazards like, potholes, or sharp edged
objects, or when sliding into a curb. The vehicle
warranty does not cover this type of damage.
Keep tires set to the correct ination pressure
and, when possible avoid contact with curbs,
potholes, and other road hazards.
Winter Tires
If your vehicle has P225/50R18 size tires, they are
classified as low-profile performance tires. These tires
are designed for very responsive driving on wet or dry
pavement. If you expect to drive on snow or ice covered
roads often, you may want to get winter tires for your
vehicle. The low-profile performance tires may not
offer the traction you would like or the same level of
performance as winter tires on snow or ice covered
roads.
Winter tires, in general, are designed for increased
traction on snow and ice covered roads. With winter
tires, there may be decreased dry road traction,
increased road noise and shorter tire tread life. After
switching to winter tires, be alert for changes in vehicle
handling and braking.
See your retailer for details regarding winter tire
availability and proper tire selection. Also, seeBuying
New Tires on page 6-75
6-57

Page 326 of 448

If you choose to use winter tires:
•Use tires of the same brand and tread type on all
four wheel positions.
•Use only radial ply tires of the same size, load
range, and speed rating as your original equipment
tires.
Winter tires with the same speed rating as your original
equipment tires may not be available for H, V, W
and ZR speed rated tires. If you choose winter tires with
a lower speed rating, never exceed the tire’s maximum
speed capability.
Tire Sidewall Labeling
Useful information about a tire is molded into its
sidewall. The examples below show a typical
passenger vehicle tire and a compact spare tire
sidewall.
(A) Tire Size
:The tire size is a combination of
letters and numbers used to define 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.Passenger (P-Metric) Tire Example
6-58

Page 327 of 448

(B) TPC Spec (Tire Performance Criteria
Specication):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 Identication Number (TIN)
:The letters
and numbers following DOT (Department of
Transportation) code is 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
seeUniform Tire Quality Grading on page 6-78.(G) Maximum Cold Ination Load Limit
:Maximum load that can be carried and the
maximum pressure needed to support that load.
(A) Temporary Use Only
:The compact
spare tire or temporary use tire has a tread life of
approximately 3,000 miles (5 000 km) and should
not be driven at speeds over 65 mph (105 km/h).
The compact spare tire is for emergency use
when a regular road tire has lost air and gone flat.Compact Spare Tire Example
6-59
