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, anti-lock brakes, traction control,
and 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 Saturn speci c wheel and tire
systems developed for your vehicle, and
have them properly installed by a Saturn
certi ed technician.
SeeBuying New Tires on page 474and
Accessories and Modi cations on page 412for

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.
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.

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 your 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 your vehicle and tire size
combination and road conditions.
Follow that manufacturer’s instructions.
To help avoid damage to your vehicle,
drive slowly, readjust or remove the device
if it is contacting your vehicle, and do
not spin your vehicle’s wheels. If you
do nd traction devices that will t,
install them on the front tires.
Accessory In ator
Your vehicle may have an accessory in ator. With
it, you can in ate things like air mattresses and
basketballs, and you can also use it to bring your
tires up to the proper pressure.
The accessory in ator is located in the rear
compartment on the driver’s side. To access the
accessory in ator, do the following:
1. Open the liftgate. SeeLiftgate on page 128
for more information.
2. Lift the lever to move the third row rear
seatback forward. SeeThird Row Seat
on page 27for more information.
3. Remove the cover by pulling the lever up.
