Buying New Tires

To find out what kind and size of tires you

need, look at the Tire-Loading Information

label.

Before changing to wheels/tires of another

size, we recommend that you contact an

authorized Saab workshop regarding

acceptable options. See also page 268

Wheels/tires combinations that are not

approved by the vehicle manufacturer can

negatively affect the car’s directional stabil-

ity, steering and braking in both wet and dry

conditions.

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.

Do not take it for granted that a wheel/tire

combination will work in the best possible

way, just because it can be fitted to the car.

To ensure that the speedometer is as accu-

rate as possible it should be reprogrammed

if wheels of a different dimension are fitted.

Contact a Saab dealer.

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.

Store wheels lying flat or hanging – never

standing upright.

NOTE

Wide wheels and tires with sidewalls that

are too low can:

• be damaged in potholes etc.

• cause springs, shock absorbers and

wheel bearings and body mountings

can be overloaded.

• cause the wheels to come into contact

with chassis and body components.

• can affect the function of the Elec-

tronic Stability Program (ESP

®

).

The speed and load limits for the tires

must not be exceeded; see page 230.

Wheels larger than 17” must not be fitted.

The maximum permissible offset is

49 mm.

WARNING

Mixing tires could cause you to lose con-

trol while driving. If you mix tires of differ-

ent sizes or types (radial and bias-belted

tires), the vehicle may not handle prop-

erly, and you could have a crash. Using

tires of different sizes may also cause

damage to your vehicle. Be sure to use

the same size and type tires on all wheels.

It’s all right to drive with your compact

spare temporarily, it was developed for

use on your vehicle. See “Compact spare

tire” on page 237.

WARNING

If you use bias-ply tires on your vehicle,

the wheel rim flanges 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.
