Non-TPC Spec rated tires may
give a low-pressure warning that
is higher or lower than the proper
warning level you would get with
TPC Spec rated tires. SeeTire
Pressure Monitor System on
page 5-44.
Your vehicle’s original equipment
tires are listed on the Tire and
Loading Information Label.
SeeLoading the Vehicle
on page 4-16, for more
information about the Tire and

Different Size Tires
and Wheels
If you add wheels or tires that are a
different size than your original
equipment wheels and tires,
this could 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 anti-lock
brakes, rollover airbags, 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.

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

Tire Chains
{CAUTION
Do not use tire chains. There is not
enough clearance. Tire chains
used on a vehicle without the
proper amount of clearance can
cause damage to the brakes,
suspension or other vehicle parts.
The area damaged by the tire
chains could cause you to lose
control of the vehicle and you or
others may be injured in a crash.
Use another type of traction device
only if its manufacturer
recommends it for use on the
vehicle and tire size combination
and road conditions. Follow that
manufacturer’s instructions. To
help avoid damage to the vehicle,
drive slowly, readjust or remove
the device if it is contacting the
vehicle, and do not spin the
vehicle’s wheels. If you do nd
traction devices that will t, install
them on the front tires.
If a Tire Goes Flat
It is unusual for a tire to blowout
while you are driving, especially if
you maintain the tires properly. See
Tires on page 5-36. If air goes
out of a tire, It is much more likely
to leak out slowly. But if you
should ever have a blowout, here
are a few tips about what to expect
and what to do:
If a front tire fails, the at tire will
create a drag that pulls the vehicle
toward that side. Take your foot
off the accelerator pedal and grip the
steering wheel rmly. Steer to
maintain lane position, and then
gently brake to a stop well out of the
traffic lane.A rear blowout, particularly on a
curve, acts much like a skid
and may require the same correction
you would use in a skid. In any
rear blowout, remove your foot from
the accelerator pedal. Get the
vehicle under control by steering the
way you want the vehicle to go. It
may be very bumpy and noisy,
but you can still steer. Gently brake
to a stop, well off the road if
possible.
