Wheels and Tires
Tires
Every new GM vehicle has
high-quality tires made by a
leading tire manufacturer.
See the warranty manual for
information regarding the tire
warranty and where to get
service. For additional
information refer to the tire
manufacturer.
{WARNING
.Poorly maintained and
improperly used tires are
dangerous.
.Overloading the tires can
cause overheating as a
result of too much flexing.
There could be a blowout and
a serious crash. SeeVehicle
Load Limits on page 9‑14.
.Underinflated tires pose the
same danger as overloaded
tires. The resulting crash
could cause serious injury.
Check all tires frequently to
maintain the recommended
pressure. Tire pressure
should be checked when the
tires are cold.
(Continued)
WARNING (Continued)
.Overinflated tires are
more likely to be cut,
punctured, or broken by a
sudden impact—such as
when hitting a pothole. Keep
tires at the recommended
pressure.
.Worn or old tires can cause a
crash. If the tread is badly
worn, replace them.
.Replace any tires that have
been damaged by impacts
with potholes, curbs, etc.
.Improperly repaired tires can
cause a crash. Only the
dealer or an authorized tire
service center should repair,
replace, dismount, and mount
the tires.

Vehicle Care 10-55
WARNING (Continued)
.Do not spin the tires in
excess of 56 km/h (35 mph)
on slippery surfaces such
as snow, mud, ice, etc.
Excessive spinning may
cause the tires to explode.
SeeTire Pressure for
High-Speed Operation on
page 10‑64 for inflation pressure
adjustment for high-speed
driving.
Winter Tires
Consider installing winter tires on
the vehicle if frequent driving on
snow or ice covered roads is
expected. All season tires provide
good overall performance on most
surfaces, but they may not offer
the traction 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 tread life. After
changing to winter tires, be alert for
changes in vehicle handling and
braking. See your dealer for details
regarding winter tire availability and
proper tire selection. Also, see
Buying New Tires on page 10‑70.
If using snow 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 the original
equipment tires.
Winter tires with the same speed
rating as the original equipment tires
may not be available for H, V, W, Y,
and ZR speed rated tires. If winter
tires with a lower speed rating are
chosen, never exceed the tire's
maximum speed capability.

10-56 Vehicle Care
Run-Flat Tires
This vehicle, when new, had run-flat
tires. There is no spare tire, no tire
changing equipment, and no place
to store a tire in the vehicle.
The vehicle also has a Tire
Pressure Monitor System (TPMS)
that indicates a loss of tire pressure
in any of the tires.
{WARNING
If the low tire warning light
displays on the instrument panel
cluster, the handling capabilities
will be reduced during severe
maneuvers. Driving too fast could
cause loss of control and you or
others could be injured. Do not
drive over 90 km/h (55 mph)
when the low tire warning light is
displayed. Drive cautiously and
check the tire pressures as soon
as possible.If a tire goes flat, there is no need to
stop on the side of the road to
change the tire. Continue driving,
however, do not drive too far or too
fast. Driving on the tire may not be
possible if there is permanent
damage. The tire can be driven with
no air pressure for up to 105 km
(65 miles) at speeds slower than
90 km/h (55 mph). The shorter the
distance and the slower the speed,
the greater the chance the tire will
not have to be replaced. As soon
as possible, contact the nearest
authorized GM or run-flat servicing
facility for inspection and repair or
replacement. When driving on a
deflated run-flat tire, avoid potholes
and other road hazards that could
damage the tire and/or wheel
beyond repair. When a tire has been
damaged, or if driven any distance
on a deflated run-flat tire, check with
an authorized run-flat tire service
center to determine whether the
tire can be repaired or should be
replaced. To maintain the run-flat
feature, all replacement tires must
be run-flat tires. To locate the nearest GM or run-flat
servicing facility, call Roadside
Assistance. See
Roadside
Assistance Program (U.S. and
Canada) on page 13‑8 orRoadside
Assistance Program (Mexico) on
page 13‑10 for details.
The valve stems on run-flat
tires have sensors that are part of
the TPMS. See Tire Pressure
Monitor System on page 10‑64.
These sensors contain batteries that
are designed to last for 10 years
under normal driving conditions.
See your dealer for wheel or sensor
replacement.
Notice: Using liquid sealants can
damage the tire valves and tire
pressure monitor sensors in the
run-flat tires. This damage is not
covered by the vehicle warranty.
Do not use liquid sealants in
run-flat tires.

Low-Profile Tires
Low‐Profile Performance Tire
The original equipment tires on
this vehicle are classified as
low‐profile performance tires.
These tires are designed for
very responsive driving on wet
or dry pavement, however, may
produce more road noise and
tend to wear faster.
Notice:Low‐profile tires are
more susceptible to damage
from road hazards or curb
impact than standard profile
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 warranty does not
cover this type of damage. Keep tires set to the correct
inflation pressure and, when
possible, avoid contact with
curbs, potholes, and other
road hazards.
Sport Cup Tires
This vehicle may come with
Michelin Pilot Sport Cup competition
oriented tires that are DOT approved
for street use. These tires are
included on the Z06 model with the
Z07 Performance Package and on
the ZR1 model with the PDE High
Performance Package. Sport Cup
tires use a special tread and
compound that provide more
grip than normal road tires.
The minimum tread depth will be
reached earlier than typical tires,
resulting in reduced tire life.
This special tread and compound
will decrease performance in cold
climates, heavy rain, and standing
water.
{WARNING
Driving on wet roads, in heavy
rain, or through standing water
with Sport Cup tires may cause
hydroplaning and loss of control.
Use extreme caution and drive
slowly on wet roads.
{WARNING
Driving with Sport Cup tires on
snow, ice, or cold road surfaces
can cause loss of control or an
accident. Sport Cup tires are a
summer season tires and are not
intended to be driven on snow,
ice, or road surfaces below
10°C (50°F). Do not drive a
vehicle with Sport Cup tires in
these conditions.

Tire Sidewall Labeling
Useful information about a tire
is molded into its sidewall.
The examples show a typical
passenger tire sidewall.
Passenger (P‐Metric) Tire Example
(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. (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 the 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

Tire Designations
Tire Size
The following is an example
of a typical passenger vehicle
tire size.
(A) Passenger (P‐Metric) Tire:
The United States version
of a metric tire sizing system.
The letter P as the first
character in the tire size
means a passenger vehicle
tire engineered to standards
set by the U.S. Tire and Rim
Association.

: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 60, as shown in
item C of the illustration, it would
mean that the tire's sidewall is
60 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
:
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.
Tire Terminology and
Definitions
Air Pressure:The amount of
air inside the tire pressing
outward on each square inch
of the tire. Air pressure is
expressed in kPa (kilopascal)
or psi (pounds per square inch).
Accessory Weight
:The
combined weight of optional
accessories. Some examples of
optional accessories are
automatic transmission, power
steering, power brakes, power
windows, power seats, and air
conditioning.
