217 Car care
WheelsAlternative wheels and tiresIf you wish to fit other tires or wheels than
those supplied with the car, consult your
Saab dealer first as to the possibilities avail-
able.
Wheels/tires combinations that are not
approved by Saab can negatively affect the
car´s directional stability, steering and brak-
ing in both wet and dry conditions.
Do not assume that a wheel/tire combina-
tion will function properly just because it will
bolt on.
The wheels and tires have been carefully
matched to the characteristics of the car and
play a key role in its outstanding roadhold-
ing and handling.
Tire pressureTires need to be inflated to suit the load car-
ried and the maximum speed the car will be
driven (see the recommended tire pres-
sures on the back cover). Tire pressure
label, see page 253.
Note that all values apply to cold tires. For
tires with an aspect ratio less than /60,
increase the tire pressure by 3 psi (20 kPa)
for rough roads with potholes to minimize
the risk of rim damage.
Never reduce the pressure of a hot tire. If the
tires are hot when you check them, only
increase the pressure, if necessary.
Soft tires will cause faster wear than
over-pressurized tires. They also increase
fuel consumption.
If a valve is leaking, simply unscrew it and fit
a new one.
Important! Remember to adjust the tire
pressures if you change the load in the car
or intend to cruise at a substantially higher
or lower speed than normal.
NOTEFor wide wheels and/or low-profile tires,
bear in mind the following:
Tires and wheels can be damaged in
potholes etc.
Springs, shock absorbers and wheel
bearings can be overloaded.
The wheels can come into contact with
chassis and body components.
The speed and load limits for the tires
must not be exceeded; see page 218.
Wheels larger than 17” must not be
fitted on the Saab 9-3. For Viggen
models the wheel should not be larger
than 17”. The maximum permissible
offset for the 9-3 is 49 mm and for the
Viggen 42 mm.
Wheels smaller than 16” must not be
fitted on Viggen models. Fitting a
smaller size wheel on a Viggen is not
possible due to the size of the brake
discs.
NOTECheck the tire pressures at least once
per month.
Underinflation is the main cause of:
Tires wearing out prematurely.
Damage to the sidewalls.
Damage to the wheels.

218 Car careRotating the tires Because of front wheel drive, the front tires
tend to wear faster than the rear ones. New
tires should always be fitted in pairs, so that
tires on the same axle have the same
amount of tread.
If swapping the complete set, e.g. winter
tires for summer tires, mark the tires
removed to ensure that they go back in the
same position (e.g. FL for front left, RL rear
left, etc.).
Store wheels lying flat or hanging – never
standing upright.
Tire markingsAn example of the meaning of the different
markings in a tire size is given below for a
tire size of 195/60 R15 88V:
Winter tiresWinter (snow) tires are recommended for
winter climates where the majority of your
driving will be done on snow and ice. Winter
tires should be fitted to all four wheels to
maintain a proper balance. Your Saab
dealer can advise you of to the correct size
tire for your car (if different from the original
size) and also supply Saab approved winter
tires pre-mounted on steel or alloy rims.Tire quality grading (cars sold in
U.S.)New tires must be graded and labeled in
accordance with new Federal regulations.
Standard tests are conducted to measure
performance in the areas of traction and
temperature resistance. Refer to the tire
sidewall for the specific quality grades of the
tires provided on your new Saab. Compact
spare tires are exempt.
DOT QUALITY GRADES
Treadwear.
Traction AA, A, B, C.
Temperature A, B, C.
All passenger car tires must conform to Fed-
eral safety requirements in addition to these
grades.
WARNING
When fitting just one new pair of tires,
these should be fitted to the rear wheels,
as these are more critical to the direc-
tional stability of the car (e.g. on braking
or in a skid). The existing rear tires should
therefore be moved to the front. Always
move left rear to left front and right rear to
right front, so that the direction of rotation
remains the same.

8 Lower the car and tighten the wheel
bolts to the correct torque in the
sequence shown (opposite pairs).
Tightening torque:
Light-alloy wheels: 80 ft.lbs (110 Nm).
Steel wheels: 80 ft.lbs (110 Nm).
Do not overtighten the bolts using an
impact wrench: not only can this
damage the wheels but it can also make
it impossible to undo the bolts using the
wheel wrench in the car’s toolkit.9 Recheck the wheel bolts after a few
miles.
Tightening torque:
Light-alloy wheels: 80 ft.lbs (110 Nm)
Steel wheels: 80 ft.lbs (110 Nm)
We advise against using wheels with open
wheel covers in winter, as the brake compo-
nents are then more exposed both to slush
and to road salt and grit.
Tire chains; see page 178.
NOTE
When refitting wheel covers (where
applicable), make sure that the valve
protrudes through the hole in the wheel
cover.
NOTESaab 9-3 Viggen: The minimum permis-
sible wheel diameter is 16”, due to the
size of the brake discs.
