222 Car care and technical informationWheels Alternative 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.
To ensure that the speedometer is as accu-
rate as possible it should be reprogrammed
if wheels of a different dimension are fitted.
Contact an authorized Saab workshop.
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). 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.
NOTEAlways consult your Saab dealer before
changing the wheels and tires on your
Saab.
For 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 and body mountings 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 223.
 Wheels larger than 17” must not be fit-
ted. The maximum permissible offset
is 49 mm.
 Tire and wheel size can affect the
function of the Electronic Stability
Program (ESP).
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.

223 Car care and technical information
Rotating tiresBecause the car has 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.
The wheels should be marked, L (left) and
R (right), when changing between summer
and winter (snow) tires. This ensures that
the direction of rotation of the wheels is the
same when they are refitted. Fit the tires in
best condition to the rear wheels.
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:
205/65 R15 94 V
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 as to the correct size
tire for your car (if different from the original
size) and also supply Saab approved winter
tires.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 wheels
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.

224 Car care and technical informationUniform Tire Quality Grading (US)Quality grades can be found where applica-
ble on the tire sidewall between tread shoul-
der and maximum section width. For exam-
ple:
Treadwear 200 Traction AA
Temperature ATreadwearThe treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions on
a specified government test course. For
example, a tire graded 150 would wear one
and one half (1 1/2) times as well on the gov-
ernment course as a tire graded 100. The
relative performance of tires depends upon
the actual conditions of their use, however,
and may depart significantly from the norm
due to variations in driving habits, service
practices and differences in road character-
istics and climate.
TractionThe traction grades, from highest to lowest,
are AA, A, B and C. These grades represent
the tire’s ability to stop on wet pavement as
measured under controlled conditions on
specified government test surfaces of
asphalt and concrete. A tire marked C may
have poor traction performance.
Wear indicatorsThe tires incorporate wear indicators in the
form of smooth, treadless strips across the
width, which become visible when only
1.6 mm of tread remains. As soon as the
indicators become visible, new tires should
be fitted without delay.
Make sure you are familiar with the legal
limit for minimum tread depth in your
country and also any regulations gov-
erning the use of winter tires.
WARNING
The traction grade assigned to a tire is
based on straight-ahead braking, traction
test and does not include acceleration,
cornering, hydroplaning or peak traction
characteristics.

225 Car care and technical information
TemperatureThe temperature grades are A (the highest),
B, and C, representing the tire’s resistance
to the generation of heat and its ability to dis-
sipate heat when tested under controlled
conditions on a specified indoor laboratory
test wheel. Sustained high temperature can
cause the material of the tire to degenerate
and reduce tire life, and excessive temper-
ature can lead to sudden tire failure. The
grade C corresponds to a level of perfor-
mance which all passenger car tires must
meet under the Federal Motor Vehicle
Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law.
Date codeTires should be regarded as perishable
goods. As the tires age, the rubber becomes
progressively harder, and the roadholding
ability of the tires diminishes. This is partic-
ularly true on winter tires.
Tires now have a date-code marking for the
year of manufacture. The first two digits
denote the week number and the two last
digits the year. The ”<” symbol points to the
year.
Accordingly, a date code of 0200 signifies
that the tire was manufactured in week 02,
2000.
WARNING
The temperature grade for a tire is estab-
lished for a tire that is properly inflated
and not overloaded. Excessive speed,
underinflation, or excessive loading,
either separately or in combination, can
cause heat buildup and possible tire fail-
ure.

226 Car care and technical informationCompact spare wheelThe compact spare is light and easy to
handle when changing the tire. Its use is
only permitted when a standard tire has sus-
tained a puncture. The maximum life of the
tire is only 2000 miles (3,500 km).
Do not exceed 50 mph (80 km/h) with the
compact spare fitted.
The compact spare should be inflated to
60 psi (420 kPa). Carry the punctured tire in
the spare-wheel well under the luggage-
compartment floor.
Have the standard tire repaired and refitted
as soon as possible (see also page 179).The spare wheel, together with the jack ,
front towrope attachment eye and toolkit, is
stowed away underneath a panel in the lug-
gage-compartment floor. The jack handle is
kept in a cover beside the spare wheel.
If you need to change a wheel, remove the
tool kit first and then the spare wheel.
The panel over the spare wheel can be held
open by hooking the handle onto the rubber
seal.
NOTETo avoid damaging a punctured alloy
wheel it can be placed outside up in the
spare-wheel well but only while driving to
the closest workshop.
A general rule is that all heavy loads must
be well secured in the luggage compart-
ment, see page 134 and 137.

227 Car care and technical information
Changing a wheel
WARNING
 The car jack is designed solely for use
in changing a wheel or fitting snow
chains. It must not be used to support
the car during repair work or servicing.
 Never crawl under a car that is
supported only by a jack.
 Special care must be taken if the car is
on a slope – use wheel chocks!
 Position chocks, one ahead and one
behind, the wheel that is diagonally
opposite to the one to be changed.
 Switch on the hazard warning lights if
the car is on a road.
 Apply the parking brake and leave the
car in gear (1st or reverse). Automatic
transmission: move selector to the
P position.
 Ensure that everybody is out of the car
before jacking it up.
 Never start the engine while the car is
jacked up.
 The jack must stand on a firm, level
surface.
 Stow the jack in the place provided for
it under the panel in the floor of the lug-
gage compartment. Secure it properly
to avert injury to passengers in the
event of a crash.
 Do not use the jack for any purpose
other than for jacking up the car.

229 Car care and technical information
If a floor jack is used, it can be applied to the
standard jacking points used by the dealer.
A floor jack can lift both front wheels or both
rear wheels off the ground simultaneously.
A jack stand must then be applied under-
neath the front of the engine subframe (at
the fixing point for the towrope-attachment
eye) or to the rear towrope-attachment eye
(or under the trailer hitch, if fitted).
1 Put the car in 1st gear (automatic trans-
mission: move selector to the P position)
and apply the parking brake.2 Wind the jack up to a suitable height
before placing it under the recess in the
sill.
Make sure that the jack fully engages
the recess in the sill and that the base of
the jack is steady and flat on the ground.
3 Remove the wheel cover (where appli-
cable).
Loosen the wheel bolts by half a turn.
4 Wind the jack to raise the wheel clear of
the ground. Remove the wheel bolts and
lift off the wheel.
5 Clean the contact surfaces between the
wheel and brake disc.
6 Fit the wheel and screw in the bolts in the
sequence shown (opposite pairs).
Tighten the bolts enough for the bolts
and wheel to be seated correctly.
7 Lower the car and tighten the wheel
bolts to the correct torque in the
sequence shown (opposite pairs).
Tightening torqueLight-alloy wheels: 80 ft.lbs. (110 Nm)
Steel wheels: 80 ft.lbs. (110 Nm)
Do not overtighten the bolts using a per-
cussion nut tightener: 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.
8 Check-tighten the wheel bolts after a
few miles.
Tightening torqueLight-alloy wheels: 80 ft.lbs. (110 Nm)
Steel wheels: 80 ft.lbs. (110 Nm)
NOTEApply the jack only to the jacking points
indicated.
NOTEWhen refitting wheel covers (where
applicable), make sure that the valve
protrudes through the hole in the wheel
cover.

230 Car care and technical information
Flat spottingAll tires get hot, especially on long journeys
or when the car is driven hard. After the car
has been parked with hot tires and the tires
have cooled down, a flat spot can appear in
the tire, where it is in contact with the
ground. The same can occur if the car has
not been moved for a long time.
Flat spots can give rise to vibration that can
be felt through the steering wheel, similar to
that experienced when the wheels need bal-
ancing. Flat spots of this type disappear
once the tires get hot again, usually after
10–15 miles (20–25 km) of driving at cruis-
ing speed.
WARNING
If the car has been driven for several
years exclusively with alloy wheels and
steel wheels are now fitted, the bolt hole
threads in the brake hubs should be
cleaned before the thinner steel wheels
are fitted. Grit, salt and rust can clog the
inner threads making it impossible to
achieve the correct tightening torque.
