11-34 Maintenance and service bel and to have a speed symbol and load index matching those shown on the tire label. Using tires of a non-specified size detracts from controllability, ride comfort, braking performance, speedometer accuracy and odometer accuracy. It also creates incorrect body-to-tire clearances and inappropriately changes the vehicle's ground clearance. All four tires must be the same in terms of manufacturer, brand (tread pattern), construction, and size. You are advised to replace the tires with new ones that are identical to those fitted as standard equipment. For safe vehicle operation, Saab recommends replacing all four tires at the same time. NOTE — All four tires must be the same in terms of manufacturer, brand (tread pattern), construction, degree of wear, speed symbol, load index and size. Mixing tires of different types, sizes or degrees of wear can result in damage to vehicle's power train. Use of different types or sizes of tires can also dangerously reduce controllability and braking performance and can lead to an accident. — Use only radial tires. Do not use radial tires together with belted bias tires and/or bias-ply tires. Doing so can dangerously reduce controllability, resulting in an accident. B00480 Unidirectional tires: Some tires have a specified direction of rotation. A tire of this type has an arrow or other mark on its side wall to indicate the direction of rotation. Install it so that the direction of rotation is correct when the vehicle is driven forward. ¢ Wheel replacement When replacing wheels due, for example, to damage, make sure the replacement wheels match the specifications of the wheels that are fitted as standard equipment. Replacement wheels are available from Saab dealers.
