The Tire and Loading
Information label indicates the
original equipment tires on the
vehicle. SeeVehicle Load Limits
on page 9-10.
Different Size Tires and
Wheels
If wheels or tires are installed that
are a different size than the original
equipment wheels and tires, vehicle
performance, including its braking,
ride and handling characteristics,
stability, and resistance to rollover
may be affected. If the vehicle has
electronic systems such as antilock
brakes, rollover airbags, traction
control, electronic stability control,
or All-Wheel Drive, the performance
of these systems can also be
affected.
{Warning
If different sized wheels are used,
there may not be an acceptable
level of performance and safety if
tires not recommended for those
wheels are selected. This
increases the chance of a crash
and serious injury. Only use GM
specific wheel and tire systems
developed for the vehicle, and
have them properly installed by a
GM certified technician.
See Buying New Tires on
page 10-58 andAccessories and
Modifications on page 10-3.
Uniform Tire Quality
Grading
The following information relates
to the system developed by the
United States National Highway
Traffic Safety Administration
(NHTSA), which grades tires by treadwear, traction, and
temperature performance. This
applies only to vehicles sold in
the United States. 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 tires,
compact 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.

10-64 Vehicle Care
{Warning
Driving on a flat tire will cause
permanent damage to the tire.
Re-inflating a tire after it has been
driven on while severely
underinflated or flat may cause a
blowout and a serious crash.
Never attempt to re-inflate a tire
that has been driven on while
severely underinflated or flat.
Have your dealer or an authorized
tire service center repair or
replace the flat tire as soon as
possible.
{Warning
Lifting a vehicle and getting under
it to do maintenance or repairs is
dangerous without the
appropriate safety equipment and
training. If a jack is provided with
the vehicle, it is designed only for
changing a flat tire. If it is used for
anything else, you or others could
be badly injured or killed if the
vehicle slips off the jack. If a jack
is provided with the vehicle, only
use it for changing a flat tire.
If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place, well off the road,
if possible. Turn on the hazard
warning flashers. See Hazard
Warning Flashers on page 6-4.
{Warning
Changing a tire can be
dangerous. The vehicle can slip
off the jack and roll over or fall
causing injury or death. Find a
level place to change the tire. To
help prevent the vehicle from
moving:
1. Set the parking brake firmly.
2. Put an automatic transmission in P (Park) or a
manual transmission in
1 (First) or R (Reverse).
3. Turn off the engine and do not restart while the vehicle
is raised.
4. Do not allow passengers to remain in the vehicle.
5. Place wheel blocks, if equipped, on both sides of
the tire at the opposite
corner of the tire being
changed.

{Warning
Idling a vehicle in an enclosed
area with poor ventilation is
dangerous. Engine exhaust may
enter the vehicle. Engine exhaust
contains carbon monoxide (CO)
which cannot be seen or smelled.
It can cause unconsciousness
and even death. Never run the
engine in an enclosed area that
has no fresh air ventilation. For
more information, see Engine
Exhaust on page 9-26.
{Warning
Overinflating a tire could cause
the tire to rupture and you or
others could be injured. Be sure
to read and follow the tire sealant
and compressor kit instructions
and inflate the tire to its
recommended pressure. Do not
exceed the recommended
pressure.
{Warning
Storing the tire sealant and
compressor kit or other
equipment in the passenger
compartment of the vehicle could
cause injury. In a sudden stop or
collision, loose equipment could
strike someone. Store the tire
sealant and compressor kit in its
original location.

Using the Tire Sealant and
Compressor Kit to Temporarily
Seal and Inflate a
Punctured Tire
Follow the directions closely for
correct sealant usage.
When using the tire sealant and
compressor kit during cold
temperatures, warm the kit in a
heated environment for five minutes.
This will help to inflate the tire
faster.If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place. Turn on the hazard
warning flashers. See
Hazard
Warning Flashers on page 6-4.
See If a Tire Goes Flat on
page 10-63 for other important
safety warnings.
Do not remove any objects that
have penetrated the tire.
1. Remove the tire sealant and compressor kit from its storage
location. See Storing the Tire
Sealant and Compressor Kit on
page 10-72.
2. Unwrap the sealant/air hose (6) and the power plug (7).
3. Place the kit on the ground. Make sure the tire valve stem is
positioned close to the ground
so the hose will reach it.
4. Remove the valve stem cap from the flat tire by turning it
counterclockwise. 5. Attach the sealant/air hose (6)
onto the tire valve stem. Turn it
clockwise until it is tight.
6. Plug the power plug (7) into the accessory power outlet in the

9. Press the on/off button (1) toturn the tire sealant and
compressor kit on.
The compressor will inject
sealant and air into the tire.
The pressure gauge (4) will
initially show a high pressure
while the compressor pushes the
sealant into the tire. Once the
sealant is completely dispersed
into the tire, the pressure will
quickly drop and start to rise
again as the tire inflates with
air only.
10. Inflate the tire to the recommended inflation
pressure using the pressure
gauge (4). The recommended
inflation pressure can be found
on the Tire and Loading
Information label. See Tire
Pressure on page 10-50.

read higher than the actual tire
pressure while the compressor
is on. Turn the compressor off
to get an accurate pressure reading. The compressor may
be turned on/off until the
correct pressure is reached.
{Caution
If the recommended pressure
cannot be reached after
approximately 25 minutes, the
vehicle should not be driven
farther. The tire is too severely
damaged and the tire sealant and
compressor kit cannot inflate the
tire. Remove the power plug from
the accessory power outlet and
unscrew the inflating hose from
the tire valve. See

sealant is distributed in the tire;
therefore, Steps 12–18 must be
done immediately after
Step 11.
Be careful while handling the
tire sealant and compressor kit
as it could be warm after
usage.
12. Unplug the power plug (7) from the accessory power outlet in
the vehicle.
13. Turn the sealant/air hose (6) counterclockwise to remove it
from the tire valve stem.
