pressed against the curb when you
park the vehicle.

If you feel unusual vibration while
driving or find it difficult to steer the ve-
hicle in a straight line, one of the tires
and/or wheels may be damaged. Drive
slowly to the nearest authorized Saab
dealer and have the vehicle inspected.
Tire pressures and wearMaintaining the correct tire pressures
helps to maximize the tires’ service lives
and is essential for good running perfor-
mance. Check and, if necessary, adjust
the pressure of each tire (including the
spare) at least once a month (for example,
during a fuel stop) and before any long
journey.Check the tire pressures when the tires
are cold. Use a pressure gauge to adjust
the tire pressures to the values shown on
the tire label. The tire label is located on
the door pillar on the driver’s side.
Driving even a short distance warms up
the tires and increases the tire pressures.
Also, the tire pressures are affected by the
outside temperature. It is best to check tire
pressure outdoors before driving the vehi-
cle.
When a tire becomes warm, the air inside
it expands, causing the tire pressure to in-
crease. Be careful not to mistakenly re-
lease air from a warm tire to reduce its
pressure.
NOTE
The air pressure in a tire increases
by approximately 4.3 psi (30 kPa, 0.3
kgf/cm
2) when the tire becomes warm.

The tires are considered cold when
the vehicle has been parked for at least
three hours or has been driven less
than one mile (1.6 km).
Incorrect tire pressures detract from con-
trollability and ride comfort, and they
cause the tires to wear abnormally.

Correct tire pressure (tread worn
evenly)
Roadholding is good, and steering is re-
sponsive. Rolling resistance is low, so fuel
consumption is also lower.
D00120
Do not let air out of warm tires to ad-
just pressure. Doing so will result in
low tire pressure.

Maintenance and service

Abnormally low tire pressure (tread
worn at shoulders)
Rolling resistance is high, so fuel con-
sumption is also higher.
Abnormally high tire pressure (tread
worn in center)
Ride comfort is poor. Also, the tire magni-
fies the effects of road-surface bumps and
dips, possibly resulting in vehicle damage.
If the label shows tire pressures for the ve-
hicle when fully loaded and for the vehicle
when towing a trailer, adjust the tire pres-
sures to the values that match current
loading conditions.

Wheel balanceEach wheel was correctly balanced when
your vehicle was new, but the wheels will
become unbalanced as the tires become
worn during use. Wheel imbalance caus-
es the steering wheel to vibrate slightly at
certain vehicle speeds and detracts from
the vehicle’s straight-line stability. It can
also cause steering and suspension sys-
tem problems and abnormal tire wear. If
you suspect that the wheels are not cor-
rectly balanced, have them checked and
adjusted by your Saab dealer. Also have
them adjusted after tire repairs and after
tire rotation.NOTELoss of correct wheel alignment* caus-
es the tires to wear on one side and re-
duces the vehicle’s running stability.
B00051
B00052
Driving at high speeds with exces-
sively low tire pressures can cause
the tires to deform severely and to
rapidly become hot. A sharp in-
crease in temperature could cause
tread separation, and destruction of
the tires. The resulting loss of vehi-
cle control could lead to an acci-
dent.

Contact your Saab dealer if you notice
abnormal tire wear.*: The suspension system is designed to hold
each wheel at a certain alignment (relative to
the other wheels and to the road) for optimum
straight-line stability and cornering perfor-
mance.
Wear indicators1) New tread
2) Worn tread
3) Tread wear indicatorEach tire incorporates a tread wear indica-
tor, which becomes visible when the depth
of the tread grooves decreases to 0.063 in
(1.6 mm). A tire must be replaced when
the tread wear indicator appears as a solid
band across the tread.
NOTEFor safety, inspect tire tread regularly
and replace the tires before their tread
wear indicators become visible.
Tire rotation
Tire wear varies from wheel to wheel. To
maximize the life of each tire and ensure
that the tires wear uniformly, it is best to
rotate the tires every 7,500 miles (12,500
km). Rotating the tires involves switching
the front and rear tires on the right-hand
side of the vehicle and similarly switching
the front and rear tires on the left-hand
side of the vehicle. (Each tire must be kept
on its original side of the vehicle.)
Replace any damaged or unevenly worn
tire at the time of rotation. After tire rota-
tion, adjust the tire pressures and make
sure the wheel nuts are correctly tight-
ened.
After driving approximately 600 miles
(1,000 km), check the wheel nuts again
and retighten any nut that has become
loose.
Tire replacementThe wheels and tires are important and in-
tegral parts of your vehicle’s design; they
cannot be changed arbitrarily. The tires fit-
ted as standard equipment are optimally
matched to the characteristics of the vehi-
cle and were selected to give the best pos-
sible combination of running performance,
ride comfort, and service life. It is essential
for every tire to have a size and construc-
tion matching those shown on the tire la-

B00327
When a tire’s tread wear indicator
becomes visible, the tire is worn be-
yond the acceptable limit and must
be replaced immediately. With a tire
in this condition, driving at high
speeds in wet weather can cause
the vehicle to hydroplane. The re-
sulting loss of vehicle control can
lead to an accident.

bel and to have a speed symbol and load
index matching those shown on the tire la-
bel.
Using tires of a non-specified size detracts
from controllability, ride comfort, braking
performance, speedometer accuracy and
odometer accuracy. It also creates incor-
rect body-to-tire clearances and inappro-
priately changes the vehicle’s ground
clearance.
All four tires must be the same in terms of
manufacturer, brand (tread pattern), con-
struction, and size. You are advised to re-
place the tires with new ones that are
identical to those fitted as standard equip-
ment.
For safe vehicle operation, Saab recom-
mends replacing all four tires at the same
time.
NOTEUnidirectional tires: Some tires have a
specified direction of rotation. A tire of
this type has an arrow or other mark on
its side wall to indicate the direction of
rotation. Install it so that the direction
of rotation is correct when the vehicle
is driven forward.

Wheel replacementWhen replacing wheels due, for example,
to damage, make sure the replacement
wheels match the specifications of the
wheels that are fitted as standard equip-
ment. Replacement wheels are available
from Saab dealers.
B00480

All four tires must be the same in
terms of manufacturer, brand
(tread pattern), construction, de-
gree of wear, speed symbol, load
index and size. Mixing tires of dif-
ferent types, sizes or degrees of
wear can result in damage to vehi-
cle’s power train. Use of different
types or sizes of tires can also
dangerously reduce controllabili-
ty and braking performance and
can lead to an accident.

Use only radial tires. Do not use
radial tires together with belted
bias tires and/or bias-ply tires. Do-
ing so can dangerously reduce
controllability, resulting in an ac-
cident.

NOTEWhen any of the wheels is removed
and replaced for tire rotation or to
change a flat tire, always check the
tightness of the wheel nuts after driv-
ing approximately 600 miles (1,000
km). If any nut is loose, tighten it to the
specified torque.
Aluminum wheelsAluminum wheels can be scratched and
damaged easily. Handle them carefully to
maintain their appearance, performance,
and safety.

When any of the wheels is removed and
replaced for tire rotation or to change a
flat, always check the tightness of the
wheel nuts after driving approximately 600
miles (1,000 km). If any nut is loose, tight-
en it to the specified torque.

Never apply oil to the threaded parts,
wheel nuts, or tapered surface of the
wheel.

Never let the wheel rub against sharp
protrusions or curbs.

Be sure to fit tire chains on uniformly
and completely around the tire, otherwise
the chains may scratch the wheel.

When wheel nuts, balance weights, or
the center cap is replaced, be sure to re-
place them with genuine Saab parts de-
signed for aluminum wheels.
Windshield washer fluidIf you spray washer fluid on the windshield
but the supply of washer fluid appears to
diminish, check the level of washer fluid in
the tank. Use only those wheels that are
specified for your vehicle. Wheels
not meeting specifications could in-
terfere with brake caliper operation
and may cause the tires to rub
against the wheel well housing dur-
ing turns. The resulting loss of vehi-
cle control could lead to an acci-
dent.
