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. See Vehicle Load
Limits 0175.
(Continued)
Warning (Continued)
.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.
.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.

266 Vehicle Care
Warning (Continued)
.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.
.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.
See Tire Pressure for
High-Speed Operation 0275 for
inflation pressure adjustment for
high-speed driving.
Winter Tires
This vehicle was not originally
equipped with winter tires. Winter
tires are designed for increased
traction on snow and ice-covered
roads. Consider installing winter
tires on the vehicle if frequent
driving on ice or snow covered
roads is expected. See your dealer
for details regarding winter tire
availability and proper tire selection.
Also, see Buying New Tires 0280.
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.
If using 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 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.
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 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

Vehicle Care 267
Warning (Continued)
drive over 80 km/h (50 mph) when
the low tire warning light is
displayed. Drive cautiously and
check the tire pressures as soon
as possible.
Run-flat tires can be driven on with
no air pressure. 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. To prevent permanent
damage, the tire can be driven with
no air pressure for up to 80 km
(50 mi) at speeds slower than
80 km/h (50 mph). 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 while deflated, 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 Customer
Assistance.
The valve stems on run-flat tires
have sensors that are part of the
TPMS. See
Tire Pressure Monitor
System 0275. These sensors
contain batteries that are designed
to last for 10 years under normal
driving conditions. See your dealer
for wheel or sensor replacement.
Caution
Using liquid sealants can damage
the tire valves and tire pressure
monitor sensors in the run-flat
tires. This damage is not covered
(Continued)
Caution (Continued)
by the vehicle warranty. Do not
use liquid sealants in run-flat
tires.
Low-Profile Tires
Low-Profile Performance Tires
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, they
may produce more road noise
and tend to wear faster.
Caution
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 (Continued)

268 Vehicle Care
Caution (Continued)
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.
Competition Oriented
Tires
This vehicle may come with P285/
30ZR19 and P335/25ZR20 Michelin
PS CUP2 competition oriented tires
that are DOT approved for street
use. Competition oriented tires use
a special tread pattern 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 pattern and compound
will have decreased performance incold climates, heavy rain, and
standing water. It is recommended
that winter tires be installed on the
vehicle when driving at
temperatures below approximately
10 °C (50 °F) or on ice or snow
covered roads. See
Winter Tires
0 266.
{Warning
Driving on wet roads, in heavy
rain, or through standing water
with competition oriented tires
may cause hydroplaning and loss
of control. Use extreme caution
and drive slowly on wet roads.
{Warning
Driving with competition oriented
tires on snow, ice, or cold road
surfaces can cause loss of control
or a crash. Competition oriented
tires are summer season tires and
are not intended to be driven on
(Continued)
Warning (Continued)
snow, ice, or road surfaces below
10 °C (50 °F). Do not drive a
vehicle with competition oriented
tires in these conditions.
Caution
Competition oriented tires have
rubber compounds that lose
flexibility and may develop
surface cracks in the tread area
at temperatures below −7 °C (20 °
F). Always store competition
oriented tires indoors and at
temperatures above −7 °C (20 °F)
when not in use. If the tires have
been subjected to −7 °C (20 °F) or
less, let them warm up in a
heated space to at least 10 °C
(50 °F) for 24 hours or more
before being installed or driving a
vehicle on which they are
installed. Do not apply heat or

tires. Always inspect tires before
use. SeeTire Inspection 0278.
Summer Tires
High Performance Summer Tires
This vehicle may come with high
performance summer tires. These
tires have a special tread and
compound that are optimized for
maximum dry and wet road
performance. This special tread and
compound will have decreased
performance in cold climates, and
on ice and snow. It is recommended
that winter tires be installed on the
vehicle if frequent driving at
temperatures below approximately
5 °C (40 °F) or on ice or snow
covered roads is expected. See
Winter Tires 0266.
Caution
High performance summer tires
have rubber compounds that lose
flexibility and may develop
surface cracks in the tread area
at temperatures below −7 °C
(20 °F). Always store high
performance summer tires
indoors and at temperatures
above −7 °C (20 °F) when not in
use. If the tires have been
subjected to −7 °C (20 °F) or less,
let them warm up in a heated
space to at least 5 °C (40 °F) for
24 hours or more before being
installed or driving a vehicle on
which they are installed. Do not
apply heat or blow heated air
directly on the tires. Always
inspect tires before use. See Tire
Inspection 0278.
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
(1) Tire Size:The tire size is a
combination of letters and
numbers used to define a
particular tire's width, height,
