Uniform Tire Quality Grading
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
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration, 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
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.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a speci ed government test course.
For example, a tire graded 150 would wear one and
a half (1.5) 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 signi cantly 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 speci ed 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.

4. Attach the sealant lling hose (A) onto the tire valve
stem. Turn it clockwise until it is tight.
Make sure the in ator kit on/off switch (B) is in the
O (off) position.
5. Plug the air compressor accessory plug (C) into an
accessory power outlet in the vehicle. See
Accessory Power Outlet(s) on page 3-15for more
information.
{CAUTION:
Idling the engine in a closed-in place or with
the climate control system off can cause
deadly carbon monoxide (CO). SeeEngine
Exhaust on page 2-28.
6. Start the vehicle. SeeStarting the Engine on
page 2-19for more information. The vehicle must be
running while using the air compressor.
{CAUTION:
In ating something too much can make it
explode, and you or others could be injured.
Be sure to read the in ator instructions, and
in ate the tire to its recommended pressure.
Do not exceed 36 psi (248 kPa).
7. Move the in ator kit switch to the I (on) position.
The in ator kit will force sealant and air into the
tire. Sealant may leak from the puncture hole until
the vehicle is driven and the hole has sealed.

pressure using the air pressure gage on the top
of the unit.
10. Turn off the air compressor by moving the switch to
the O (off) position.
{CAUTION:
Storing the tire in ator 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 in ator kit in the
proper place.
11. Place the equipment in the original location in the
trunk of your vehicle.
