If your vehicle has 215/45ZR17 size tires, they are
directional tires and must roll in a certain direction
for the best overall performance. The direction is
shown by an arrow on the tire sidewall. Because
these tires are directional, they should be rotated as
shown here. These tires should only be moved from
front to rear and rear to front on the same side of
the vehicle.
Do not include the compact spare tire in your tire
rotation.After the tires have been rotated, adjust the front
and rear ination pressures as shown on the
Tire and Loading Information label. SeeLoading
Your Vehicle on page 250for an example of
the tire and loading information label and
its location on your vehicle. Make certain that all
wheel nuts are properly tightened. See “Wheel Nut
Torque” underCapacities and Specications on
page 384.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel bolts
become loose after a time. The wheel
could come off and cause an accident.
When you change a wheel, remove any
rust or dirt from places where the wheel
attaches to the vehicle. In an emergency,
you can use a cloth or a paper towel to do
this; but be sure to use a scraper or wire
brush later, if you need to, to get all the
rust or dirt off. SeeChanging a Flat Tire

When It Is Time for New Tires
One way to tell when it
is time for new tires is
to check the treadwear
indicators, which will
appear when your tires
have only 1/16 inch
(1.6 mm) or less of tread
remaining.
You need a new tire if any of the following
statements are true:
You can see the indicators at three or more
places around the tire.
You can see cord or fabric showing through
the tire’s rubber.
The tread or sidewall is cracked, cut, or
snagged deep enough to show cord or fabric.
The tire has a bump, bulge, or split.
The tire has a puncture, cut, or other damage
that cannot be repaired well because of the
size or location of the damage.
Buying New Tires
GM has developed and matched specic tires for
your vehicle. The original equipment tires
installed on your vehicle, when it was new,
were designed to meet General Motors Tire
Performance Criteria Specication (TPC spec)
system rating. If you need replacement tires,
GM strongly recommends that you get tires with
the same TPC Spec rating. This way, your vehicle
will continue to have tires that are designed to
give the same performance and vehicle safety,
during normal use, as the original tires.

GM’s exclusive TPC Spec system considers over
a dozen critical specications that impact the
overall performance of your vehicle, including
brake system performance, ride and handling,
traction control, and tire pressure monitoring
performance. GM’s TPC Spec number is molded
onto the tire’s sidewall by the tire manufacturer.
If the tires have an all-season tread design,
the TPC spec number will be followed by an
MS for mud and snow. SeeTire Sidewall Labeling
on page 330for additional information.
{CAUTION:
Mixing tires could cause you to lose
control while driving. If you mix tires of
different sizes, brands, or types (radial
and bias-belted tires), the vehicle may not
handle properly, and you could have a
crash. Using tires of different sizes,
CAUTION: (Continued)
CAUTION: (Continued)
brands, or types may also cause damage
to your vehicle. Be sure to use the correct
size, brand, and type of tires on all
wheels. It is all right to drive with your
compact spare temporarily, as it was
developed for use on your vehicle.
SeeCompact Spare Tire on page 365.
{CAUTION:
If you use bias-ply tires on your vehicle,
the wheel rim anges could develop
cracks after many miles of driving. A tire
and/or wheel could fail suddenly, causing
a crash. Use only radial-ply tires with the
wheels on your vehicle.

If you must replace your vehicle’s tires with those
that do not have a TPC Spec number, make
sure they are the same size, load range, speed
rating, and construction type (radial and
bias-belted tires) as your vehicle’s original tires.
Your vehicle’s original equipment tires are listed on
the Tire and Loading Information label. This
label is attached to the vehicle’s center pillar
(B-pillar). SeeLoading Your Vehicle on page 250,
for more information about the Tire and Loading
Information label and its location on your vehicle.
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 specic wheel and
tire systems developed for your vehicle,
and have them properly installed by a
Saturn certied technician.
SeeBuying New Tires on page 341and
Accessories and Modications on page 270for
additional information.

Tire Chains
{CAUTION:
If your vehicle has P195/60R15,
P205/55R16 or 215/45ZR17 size tires, 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,
CAUTION: (Continued)
CAUTION: (Continued)
re-adjust or remove the device if it is
contacting your vehicle, and do not spin
your wheels.
If you do nd traction devices that will t,
install them on the front tires.
Notice:If your vehicle has a tire size other than
P195/60R15, P205/55R16 or 215/45ZR17 size
tires, use tire chains only where legal and only
when you must. Use only SAE Class “S” type
chains that are the proper size for your tires.
Install them on the front tires and tighten them
as tightly as possible with the ends securely
fastened. Drive slowly and follow the chain
manufacturer’s instructions. If you can hear the
chains contacting your vehicle, stop and
retighten them. If the contact continues,
slow down until it stops. Driving too fast or
spinning the wheels with chains on will
damage your vehicle.

6. Place the smaller jack hold-down nut in a safe
place for use when you put the compact
spare tire back into the trunk.
7. Remove the plastic sleeve from the stow bolt
extension rod. Secure the jack and road
wheel using the larger plastic retainer.
The compact spare tire is for temporary use only.
Replace the compact spare with a full-size tire
as soon as possible.
Compact Spare Tire
Although the compact spare tire was fully inated
when the vehicle was new, it can lose air after
a time. Check the ination pressure regularly.
It should be 60 psi (420 kPa).
After installing the compact spare on the vehicle,
stop as soon as possible and make sure the
spare tire is correctly inated. The compact spare
is made to perform well at speeds up to 65 mph
(105 km/h) for distances up to 3,000 miles(5 000 km), so you can nish your trip and have
the full-size tire repaired or replaced at your
convenience. Of course, it is best to replace the
spare with a full-size tire as soon as possible.
The spare tire will last longer and be in good
shape in case it is needed again.
Notice:When the compact spare is installed,
do not take your vehicle through an automatic
car wash with guide rails. The compact
spare can get caught on the rails. That can
damage the tire and wheel, and maybe
other parts of your vehicle.
Do not use the compact spare on other vehicles.
And do not mix the compact spare tire or
wheel with other wheels or tires. They will not t.
Keep the spare tire and its wheel together.
Notice:Tire chains will not t your compact
spare. Using them can damage your vehicle
and can damage the chains too. Do not use tire
chains on your compact spare.
