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.

10-64 Vehicle Care
Tire Pressure for
High-Speed Operation
{WARNING
Driving at high speeds, 160 km/h
(100 mph) or higher, puts an
additional strain on tires.
Sustained high-speed driving
causes excessive heat buildup
and can cause sudden tire failure.
You could have a crash and you
or others could be killed. Some
high-speed rated tires require
inflation pressure adjustment for
high-speed operation. When
speed limits and road conditions
are such that a vehicle can be
driven at high speeds, make sure
the tires are rated for high-speed
operation, in excellent condition,
and set to the correct cold tire
inflation pressure for the
vehicle load.The tires require inflation pressure
adjustment when driving the vehicle
at speeds of 282 km/h (175 mph) or
higher, where it is legal. Set the cold
inflation pressure to the maximum
inflation pressure shown on the
tire sidewall, or 265 kPa (38 psi),
whichever is lower. See the
example following. Return the tires
to the recommended cold tire
inflation pressure when high-speed
driving has ended. See
Vehicle
Load Limits on page 9‑14.
Example:
The maximum load and inflation
pressure molded on the tire
sidewall, in small letters,
near the rim flange. It will read
something like this: Maximum load
690 kg (1521 lbs) 300 kPa (44 psi)
Max. Press.
For this example, set the inflation
pressure for high‐speed driving at
265 kPa (38 psi). Racing or other competitive driving
may affect the warranty coverage of
the vehicle. See the warranty
booklet for more information.Tire Pressure Monitor
System
The Tire Pressure Monitor System
(TPMS) uses radio and sensor
technology to check tire pressure
levels. The TPMS sensors monitor
the air pressure in your tires and
transmit tire pressure readings to a
receiver located in the vehicle.
Each tire, including the spare
(if provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on the
vehicle placard or tire inflation
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or
tire inflation pressure label, you
should determine the proper tire
inflation pressure for those tires.)

10-68 Vehicle Care
Tire Inspection
We recommend that the tires,
including the spare tire, if the
vehicle has one, be inspected
for signs of wear or damage at
least once a month.
Replace the tire if:
.The indicators at three or
more places around the tire
can be seen.
.There is 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.
Tire Rotation
If the vehicle has non-directional
tires, they should be rotated
every 12 000 km/7,500 mi.
SeeMaintenance Schedule on
page 11‑3.
Tires are rotated to achieve
uniform wear for all tires.
The first rotation is the most
important.
Any time unusual wear is
noticed, rotate the tires as soon
as possible and check the
wheel alignment. Also check
for damaged tires or wheels.
See When It Is Time for New
Tires on page 10‑69 andWheel
Replacement on page 10‑74.
Directional tires should not be
rotated. Each tire and wheel
should be used only in the
position it is in. Directional tires
will have an arrow on the tire indicating the proper direction of
rotation or will have“left”
or“right”
molded on the sidewall.
Different tire sizes should not be
rotated front to rear.
Use this rotation pattern if the
vehicle has different size tires
on the front and rear and they
are non-directional.

10-70 Vehicle Care
The rubber in tires ages over time.
This also applies for the spare tire,
if the vehicle has one, even if it is
never used. Multiple conditions
including temperatures, loading
conditions, and inflation pressure
maintenance affect how fast aging
takes place. Tires will typically
need to be replaced due to wear
before they may need to be
replaced due to age. Consult the tire
manufacturer for more information
on when tires should be replaced.
Vehicle Storage
Tires age when stored normally
mounted on a parked vehicle.
Park a vehicle that will be stored for
at least a month in a cool, dry, clean
area away from direct sunlight to
slow aging. This area should be
free of grease, gasoline, or other
substances that can deteriorate
rubber.Parking for an extended period can
cause flat spots on the tires that
may result in vibrations while
driving. When storing a vehicle for
at least a month, remove the tires
or raise the vehicle to reduce the
weight 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 systemperformance, 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. See
Tire Sidewall Labeling on
page 10‑58, for additional
information.
GM recommends replacing all the
tires at the same time. 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.
See Tire Inspection on page 10‑68
and Tire Rotation on page 10‑68.

Vehicle Care 10-73
The grades are molded on the
sidewalls of most passenger car
tires. The Uniform Tire Quality
Grading (UTQG) system
does not apply to deep tread,
winter-type snow tires,
space-saver, or temporary use
spare tires, tires with nominal
rim diameters of 10 to 12 inches
(25 to 30 cm), or to some
limited-production tires.
While the tires available on
General Motors passenger cars
and light trucks may vary with
respect to these grades, they
must also conform to federal
safety requirements and
additional General Motors Tire
Performance Criteria (TPC)
standards.
All Passenger Car Tires Must
Conform to Federal Safety
Requirements In Addition To
These Grades.Treadwear
The treadwear grade is a
comparative rating based on the
wear rate of the tire when tested
under controlled conditions on
a specified government test
course. For example, a tire
graded 150 would wear one and
a half (1½) times as well on the
government course as a tire
graded 100. The relative
performance of tires depends
upon the actual conditions of
their use, however, and may
depart significantly from the
norm due to variations in
driving habits, service practices
and differences in road
characteristics and climate.
Traction
–AA, A, B, C
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.

If a Tire Goes Flat
It is unusual for a tire to blowout
while driving, especially if the tires
are maintained properly. If air goes
out of a tire, it is much more likely
to leak out slowly. SeeTires on
page 10‑54 for additional
information. But if there ever is a
blowout, here are a few tips about
what to expect and what to do:
If a front tire fails, the flat tire
creates a drag that pulls the vehicle
toward that side. Take your foot off
the accelerator pedal and grip the
steering wheel firmly. Steer to
maintain lane position, and then
gently brake to a stop, well off the
road, if possible.
A rear blowout, particularly on a
curve, acts much like a skid and
may require the same correction as
used in a skid. Stop pressing the
accelerator pedal and steer to straighten the vehicle. It may be
very bumpy and noisy. Gently brake
to a stop, well off the road,
if possible.
The vehicle has no spare tire, no
tire changing equipment, and no
place to store a tire.
The vehicle, when new, had run-flat
tires. This type of tire can operate
effectively with no air pressure so
there is no need to stop on the side
of the road to change a flat tire.
If driving on a deflated run-flat tire
for 40 km (25 mi) or less and at
speeds of 90 km/h (55 mph) or less,
there is a good chance the tire can
be repaired. The Tire Pressure
Monitor System (TPMS) will show
if a tire has lost pressure. See
Run-Flat Tires on page 10‑56
and
Tire Pressure Monitor System on
page 10‑64.{WARNING
Special tools and procedures are
required to service a run-flat tire.
If these special tools and
procedures are not used, injury
or vehicle damage may occur.
Always be sure the proper tools
and procedures, as described in
the service manual, are used.
