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
norm due to variations in driving
habits, service practices and
differences in road
characteristics and climate.Traction
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.
Temperature
The temperature grades are A
(the highest), B, and C,
representing the tire's resistance
to the generation of heat and its
ability to dissipate heat when
tested under controlled
conditions on a specified indoor

284 Vehicle Care
laboratory test wheel. Sustained
high temperature can cause the
material of the tire to degenerate
and reduce tire life, and
excessive temperature can lead
to sudden tire failure. The grade
C corresponds to a level of
performance which all
passenger car tires must meet
under the Federal Motor Safety
Standard No. 109. Grades B and
A represent higher levels of
performance on the laboratory
test wheel than the minimum
required by law. Warning: The
temperature grade for this tire is
established for a tire that is
properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive
loading, either separately or in
combination, can cause heat
buildup and possible tire failure.Wheel Alignment and Tire
Balance
The tires and wheels were aligned
and balanced at the factory to
provide the longest tire life and best
overall performance. Adjustments to
wheel alignment and tire balancing
are not necessary on a regular
basis. Consider an alignment check
if there is unusual tire wear. If the
vehicle is vibrating when driving on
a smooth road, the tires and wheels
may need to be rebalanced. See
your dealer for proper diagnosis.
Road Imperfections/Crown Effects
The vehicle's precise steering and
handling make it very responsive to
road surface feedback. A slight pull
may be felt in the steering
depending on the crown of the road
and/or other road surface variations
such as troughs or ruts. This is
normal and the vehicle does not
require service.Tire Chatter/Hop
When driving at slow speeds and in
very tight turns, the vehicle may
have tire chatter/hop. This is normal
and the vehicle does not require
service.
Wheel Replacement
Replace any wheel that is bent,
cracked, or badly rusted or
corroded. If wheel nuts keep coming
loose, the wheel, wheel bolts, and
wheel nuts should be replaced.
If the wheel leaks air, replace it.
Some aluminum wheels can be
repaired. See your dealer if any of
these conditions exist.
Your dealer will know the kind of
wheel that is needed.
Each new wheel should have the
same load-carrying capacity,
diameter, width, offset, and be
mounted the same way as the one it
replaces.
Replace wheels, wheel bolts,
or wheel nuts with new GM original
equipment parts.

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 0142.
See If a Tire Goes Flat 0286 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
0 294. 2. Unwrap the sealant/air hose (6)
and the power plug (8).
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 (8) into the accessory power outlet in the
vehicle. Unplug all items from
other accessory power outlets.
See Power Outlets 0101.
If the vehicle has an accessory
power outlet, do not use the
cigarette lighter.
If the vehicle only has a
cigarette lighter, use the
cigarette lighter.
Do not pinch the power plug
cord in the door or window. 7. Start the vehicle. The vehicle
must be running while using
the air compressor.
8. Press and turn the selector switch (1) counterclockwise to
the Sealant + Air position.
9. Press the on/off button (2) to turn the tire sealant and
compressor kit on.
The compressor will inject
sealant and air into the tire.
The pressure gauge (3) 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 (3). The recommended
inflation pressure can be found
on the Tire and Loading
Information label. See Tire
Pressure 0274.

10. Inflate the tire to the recommended inflation
pressure using the pressure

inflation pressure can be found
on the Tire and Loading
Information label. See Tire
Pressure 0274.
The pressure gauge (3) may
read higher than the actual tire
pressure while the compressor
is on. Turn the compressor off
to get an accurate reading. The
compressor may be turned on/
off until the correct pressure is
reached.
If you inflate the tire higher
than the recommended
pressure you can adjust the
excess pressure by pressing
the pressure deflation
button (4) until the proper
pressure reading is reached.
