ingly trained personnel. If necessary, have the vehicle towed there. Tire damage can be extremely dangerous for vehicle occupants and other road users.< Retreaded tires BMW does not recommend the use of retreaded tires; otherwise, driving safety may be reduced. Possible variations in the design and the age - which could be substantial - of the tire casing structures can lead to unusually rapid wear.< Run-flat tires* The right wheels and tires BMW recommends that you use only wheel and tire combinations that BMW has tested and approved for your particular vehicle. Variations in factors such as manufacturing tolerances mean that even wheels and tires with identical official size ratings could actually have different dimensions than the approved units - these differences could lead to body contact, and with it, the risk of severe accidents. If non-approved wheels and tires are used, BMW cannot evaluate their suitability, and therefore cannot be held liable for driving safety.< You can ask your BMW center for the right wheel and tire combination. The correct wheel and tire combination affects various systems whose function would otherwise be impaired, such as ABS or DSC. To maintain good handling and vehicle response, use only tires of a single tread configuration from a single manufacturer. After a flat tire, always remember to have the original wheel and tire combination remounted on the vehicle as soon as possible. To continue driving with a damaged tire: > When equipped with Flat Tire Monitor, refer to Indication of a flat tire on page 91. > When equipped with Tire Pressure Monitor, refer to Low tire pressure message on page 93. New wheels and tires Only have new wheels and tires mounted by a BMW center or a tire specialist that works in accordance with BMW guidelines and uses appropriately trained personnel. If this work is not carried out properly, there is a danger of subsequent damage and related safety hazards.< Wheels with electronics for TPM Tire Pressure Monitor* When mounting new tires or changing over from summer to winter tires, or vice versa, only use wheels with TPM electronics; otherwise the Tire Pressure Monitor may not be able to detect a flat tire, refer to page 91. Your BMW center will be glad to advise you. 205 Online Edition for Part no. 01 41 0 013 316 - © 02/07 BMW AG Reference Mobility Communications Entertainment You will recognize run-flat tires by a circular symbol containing the letters RSC on the side of the tire.
