Correct wheels and tires BMW recommends using only wheels and tires that have been approved by BMW for your particular vehicle model, otherwise body contact and serious accidents can result despite the use of the same nominal size, e.g. due to manufacturing tolerances. If nonapproved wheels and tires are used, BMW cannot evaluate their suitability, and therefore cannot be held liable for driving safety.< You can inquire about the correct wheel/tire combination at your BMW center. The correct combination of wheels and tires is also necessary to ensure reliable operation of various vehicle systems such as ABS and DSC. To maintain good handling and vehicle response, only use tires of a single brand and tread configuration. After a tire has been damaged, for instance, mount the original wheel and tire combination again as soon as possible. When properly used, these tires meet the highest standards in terms of safety and handling characteristics.
