2003 Saab 9-3 Owner's Manual - Page 206

206 Car care NOTICE Always consult your Saab dealer before changing the car's wheels or tires on your Saab. Wide wheels and tires with side walls that are too low can: • be damaged in potholes, etc. • cause springs, shock absorbers and wheel bearings and body mountings to be overloaded • cause the wheels to come into contact with chassis and body components • affect the function of the Electronic Stability Program (ESP). The speed and load limits of the tires must not be exceeded; see page 209. Wheels larger than 18" must not be fitted on the Saab 9-3. The permissible offset is 1.61 inch (41 mm). The wheels and tires have been carefully matched to the characteristics of the car and play a key role in its outstanding roadholding 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 accurate as possible it should be reprogrammed if wheels of a different dimension are fitted. Contact a Saab dealer. Wheels Alternative wheels and tires If you wish to fit other tires or wheels than those supplied with the car, consult your Saab dealer first as to the possibilities available. Wheels/tires combinations that are not approved by Saab can negatively affect the car's directional stability, steering and braking in both wet and dry conditions.
