Wheel Alignment and Tire
BalanceThe wheels on your vehicle were aligned
and balanced carefully at the factory to give
you the longest tire life and best overall per-
formance.
Scheduled wheel alignment and wheel bal-
ancing are not needed. However, if you
notice unusual tire wear or your vehicle pull-
ing one way or the other, the alignment may
need to be reset. If you notice your vehicle
vibrating when driving on a smooth road,
your wheels may need to be rebalanced.Wheel ReplacementReplace any wheel that is bent, cracked or
badly rusted or corroded. If wheel nuts keep
coming loose, the wheel, wheel bolts and
wheel nuts should be replaced. If the wheel
leaks air, replace it (except some aluminum
wheels, which can sometimes be repaired).
See your dealer if any of these conditions
exist.
Your dealer will know the kind of wheel you
need.
Each new wheel should have the same
load-carrying capacity, diameter, width,
offset and be mounted the same way as the
one it replaces.
If you need to replace any of your wheels,
wheel bolts or wheel nuts, replace them only
with new Saab original equipment parts.
This way, you will be sure to have the right
wheel, wheel bolts and wheel nuts for your
vehicle.
Notice:
The wrong wheel can also cause
problems with bearing life, brake cool-
ing, speedometer or odometer calibra-
tion, headlamp aim, bumper height, vehi-
cle ground clearance and tire or tire
chain clearance to the body and chassis.
See “Changing a tire” on page 248.Used Replacement Wheels
WARNING
Using the wrong replacement wheels,
wheel bolts or wheel nuts on your vehicle
can be dangerous. It could affect the
braking and handling of your vehicle,
make your tires lose air and make you
lose control. You could have a collision in
which you or others could be injured.
Always use the correct wheel, wheel bolts
and wheel nuts for replacement.
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.
WARNING
Putting a used wheel on your vehicle is
dangerous. You can’t know how it’s been
used or how far it’s been driven. It could
fail suddenly and cause a crash. If you
have to replace a wheel, use a new GM
original equipment wheel.

Tire Sidewall LabelingUseful information about a tire is molded
into it´s sidewall.
Tire size: The tire size ia a combination of
letters and numbers used to define a partic-
ular tire´s width, height, aspect ratio, con-
struction type and service description.
Department of Transportation (DOT):
The Department of Transportation (DOT)
code indicates that the tire is in compliance
with the U.S. Department of Transportation
Motor Vehicle Safety standards.
Tire Identification Number (TIN): The let-
ters and numbers following DOT code are
the Tire Identification Number (TIN). The
TIN shows the manufacturer and plant
code, tire size, and date the tire was manu-
factured. The TIN is molded onto both sides
of the tire.
Tire Ply Material: The type of cord and
number of plies in the sidewall and under
the tread.Uniform Tire Quality Grading (UTQG):
Tire manufacturers are required to grade
tires based on the performance factors:
treadwear, traction and temperature resis-
tance. For more information see “Uniform
Tire Quality Grading” on page 238.
Maximum Cold Inflation Load Limit: Max-
imum load that can be carried and the max-
imum pressure needed to support that load.
For information on recommended tire pres-
sure see “Recommended lowest tire pres-
sure, cold tires” on page 277 and “Loading
Your Vehicle” on page 243.
Tire SizeThe following illustration shows an example
of a typical passenger car tire size.
Tire Width: The three-digit number indi-
cates the tire section width in millimeters
from sidewall to sidewall.215/55 R 16 93 H

242 Car careAspect ratio: A two-digit number that indi-
cates the tire height-to-width measure-
ments. For example, if the tire size aspect
ratio is “55”, as shown in item “C” of the illus-
tration, it would mean that the tire´s sidewall
is 55% as high as it is wide.
Belt Rating: A letter code is used to indicate
the type of ply construction in the tire. The
letter “R” means radial ply construction; the
letter “D” means diagonal or bias ply con-
struction; and the letter “B” means belted-
bias ply construction.
Rim Diameter: Diameter of the wheel in
inches.
Load range: The load range represents the
load carry capacity a tire is certified to carry.
Speed Rating: The maximum speed that a
tire is certified to carry a load. Speed ratings
range from “A” to “Z”.

Loading Your VehicleThis is an example of what your vehicle´s
Tire-Loading Information/Certification label
might look like. It is located on the B-pillar
and shows how much weight your vehicle
may properly carry. The label tells you the
proper size, and recommended inflation
pressures for the tires on your vehicle. It
also gives you important information about
the number of people that can be in your
vehicle and the total weight that you can
carry. This weight is called the Vehicle
Capacity Weight, and includes the weight of
all occupants, cargo and all nonfactory-
installed options.
Tire Terminology and DefinitionsAir Pressure: The amount of air inside the
tire pressing outward on each square inch of
the tire. Air pressure is expressed in pounds
per square inch (psi) or kilopascal (kPa).
Accessory Weight: This means the com-
bined weight of optional accessories, for
example, automatic transmission, power
steering, power brakes, power windows,
power seats, radio and air conditioning.
Aspect Ratio: The relationship of a tire´s
height to its width.
Belt: A rubber coated layer of cords that is
located between the plies and the tread.
Cords may be made from steel or other rein-
forcing materials.
Bias Ply Tire: A pneumatic tire in which the
ply cords that extend to the beads are laid at
alternate angles substantially less than 90
degrees to the centerline of the tread.
Cold Inflation Pressure: The amount of air
pressure in a tire, measured in pounds per
square inch (psi) or kilopascal (kPa), before
a tire has built up heat from driving. See
“Inflation - Tire Pressure” on page 234.
Curb weight: This means the weight of a
motor vehicle with standard and optional
equipment including the maximum capacity
of fuel, oil and coolant, without passengers
and cargo.DOT Markings: A code molded into the
sidewall of a tire signifying that the tire is in
compliance with the U.S. Department of
Transportation motor vehicle safety stan-
dards. The DOT code includes the Tire
Identification Number (TIN), an alphanu-
meric designator which can also identify the
tire manufacturer, production plant, brand
and date of production.
GVWR: Gross Vehicle Weight Rating see
“Loading Your Vehicle” on page 243.
GAWR FRT: Gross Axle Weight Rating for
the front axle, see “Loading Your Vehicle”
on page 269.
GAWR RR: Gross Axle Weight Rating for
the rear axle, see “Loading Your Vehicle” on
page 243.
Intended Outboard Sidewall: The side of
an asymmetrical tire that must always face
outward when mounted on a vehicle.
Kilopascal (kPa): The metric unit for air
pressure. There are 6.9 kPa to one psi.
Light Truck (LT-Metric) Tire: A tire used
on light duty trucks and some multipurpose
passenger vehicles.
Load Index: An assigned number ranging
from 1 to 279 that corresponds to the load
carrying capacity of a tire.
This label can only be found on vehicles
sold in the U.S.
Vehicles sold in Canada have the tire
information label in the glove box, see

249 Car care
When the car has to be lifted, the jack must
be positioned at one of the four jacking
points (front or rear) under the sill members.
If a floor jack is used, the lifting plate must
be positioned under the normal jacking
points, see illustration. If the car is equipped
with a towbar, the jack can also be placed
under this.
1 Wind the jack up to a suitable height
before placing it under the jacking point.
Each jacking point is indicated by an
arrow on the sill (see illustration).
Make sure that the jack fully engages
the jacking point in the underside of the
sill member and that the entire foot of the
jack is steady and flat on the ground.
The jack must not stand on snow, ice or
similar.
Wind up the jack until it just begins to lift
the car.2 It is not necessary to remove the wheel
cover.
If, none the less, you wish to remove the
wheel cover, take hold of the outer edge
and pull it straight out.
Loosen the wheel bolts half a turn.
3 Wind the jack to raise the wheel clear of
the ground. Remove the wheel bolts and
lift off the wheel.4 Clean any rust or dirt from the contact
surfaces between the wheel and brake
disc. Do not wipe away the grease in the
wheel hub.
5 Add a thin layer of grease on the bolts
before fitting, see page 251. Fit the
wheel and screw in the bolts in the
sequence shown on page 251 (opposite
pairs).
Tighten the bolts enough for the bolts
and wheel to be seated correctly.
6 Lower the car and tighten the wheel
bolts to torque in sequence as shown on
the following page.
Tightening torque:
Light-alloy wheels: 80 ft.lb. (110 Nm).
Steel wheels: 80 ft.lb. (110 Nm).NOTICEApply the jack only to the jacking points
indicated on the body.
