Before changing to wheels/tires of another size, we recommend that you contact an authorized Saab workshop regarding acceptable options. See also page 294 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. Treadwear indicator 247 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. 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. Treadwear indicators The tires incorporate wear indicators in the form of smooth, treadless strips across the width, which become visible when only 2/32" (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 governing the use of winter (snow) tires.
