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.

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.
Quality grades can be found
where applicable on the tire
sidewall between tread shoulder
and maximum section width. For
example:
Treadwear 200 Traction AA
Temperature A
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
one-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

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 0164.
{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 automatictransmission in P (Park) or a
manual transmission in

and even death. Never run the
engine in an enclosed area that
has no fresh air ventilation. For
more information, seeEngine
Exhaust 0200.
{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

sealant and compressor kit in its
original location.
If this vehicle has a tire sealant and
compressor kit, there may not be a
spare tire or tire changing
equipment, and on some vehicles
there may not be a place to store
a tire.
The tire sealant and compressor
can be used to temporarily seal
punctures up to 6 mm (0.25 in) in
the tread area of the tire. It can also
be used to inflate an
underinflated tire.
If the tire has been separated from
the wheel, has damaged sidewalls,
or has a large puncture, the tire is
too severely damaged for the tire

Compact Spare Tire
{Warning
Driving with more than one
compact spare tire at a time could
result in loss of braking and
handling. This could lead to a
crash and you or others could be
injured. Use only one compact
spare tire at a time.
If this vehicle has a compact spare
tire, it was fully inflated when new;
however, it can lose air over time.
Check the inflation pressure
regularly. It should be 420 kPa
(60 psi).
Stop as soon as possible and check
that the spare tire is correctly
inflated after being installed on the
vehicle. The compact spare tire is
designed for temporary use only.
The vehicle will perform differently
with the spare tire installed and it is
recommended that the vehicle
speed be limited to 80 km/h
(50 mph). To conserve the tread of the spare tire, have the standard tire
repaired or replaced as soon as
convenient and return the spare tire
to the storage area.
When using a compact spare tire,
the ABS and Traction Control
systems may engage until the spare
tire is recognized by the vehicle,
especially on slippery roads. Adjust
driving to reduce possible
wheel slip.
Performance of the All-Wheel
Drive (AWD) system will be
automatically reduced to protect the
system when using the compact
spare. To restore the AWD and
prevent excessive wear on the
clutch in the AWD, replace the
compact spare tire with a full-size
tire as soon as possible.
Caution
When the compact spare is
installed, do not take the vehicle
through an automatic car wash
