Different Size Tires and Wheels
If you add wheels or tires that are a different size than
your original equipment wheels and tires, this may affect
the way your vehicle performs, including its braking, ride
and handling characteristics, stability, and resistance
to rollover. Additionally, if your vehicle has electronic
systems such as, antilock brakes, traction control, and
electronic stability control, the performance of these
systems can be affected.
{CAUTION:
If you add different sized wheels, your
vehicle may not provide an acceptable
level of performance and safety if tires not
recommended for those wheels are selected.
You may increase the chance that you will crash
and suffer serious injury. Only use GM speci c
wheel and tire systems developed for your
vehicle, and have them properly installed
by a GM certi ed technician.
SeeBuying New Tires on page 5-76andAccessories
and Modifications on page 5-4for additional information.
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 (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-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.

Tire Sealant
Read and follow the safe handling instructions on the
sealant canister.
The sealant can temporarily seal small punctures in the
tread area of the tire. The sealant cannot seal sidewall
damage, large punctures, or a tire that has unseated
from the wheel. SeeRoadside Service on page 7-7if
you need assistance.
The sealant can only be used to seal one tire. After
usage, the sealant canister and sealant lling hose
assembly must be replaced at a dealer/retailer. See
Removal and Installation of Sealant Canister later in
this section.
Check the tire sealant expiration date on the sealant
canister. The sealant might not be effective beyond
the expiration date. If needed, see your dealer/retailer
for a replacement canister.

The sealant and compressor kit will inject sealant
and air into the tire. Sealant may leak from the
puncture until the vehicle is driven and the hole
has sealed.
The pressure gage (C) 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 in ates with air.
