Wheels and tires90age and related safety hazards. Make sure that the new wheels are balanced. <Retreaded tiresBMW does not recommend the use of retreaded tires; otherwise, driving safety may be reduced. The causes for this include the possibly different tire casing structures and the often wide variations in their age, which can result in a limited service life. <The right wheels and tiresBMW recommends that you use only wheel and tire combinations that BMW has tested and approved for your particular vehicle. Variations in factors such as manufac-turing 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 acci-dents. 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 Sports Activity Vehicle Center for the correct wheel-and-tire combina-tion.The correct wheel-and-tire combination affects various systems whose function would other-wise be impaired, e.g. ABS, DSC or xDrive.To maintain good handling and vehicle response, use only tires of a single tread config-uration from a single manufacturer. After a flat tire, always have the original wheel-and-tire combination remounted on the vehicle as soon as possible.Wheels equipped with electronics for TPM Tire Pressure MonitorWhen installing new tires or when changing from summer tires to winter tires or vice versa, only use wheels equipped with TPM electron-ics; otherwise, the Tire Pressure Monitor can-not detect a flat tire, refer to page 52. Your BMW Sports Activity Vehicle Center will be happy to advise you in this regard.Recommended tire brandsBMW recommends particular tire brands for each tire size. You will recognize them by the clearly visible BMW identification on the tire sidewall.With proper use, these tires meet the highest standards for safety and handling characteris-tics.Special characteristics of winter tiresBMW recommends winter tires for use in cold winter driving conditions. Although all-season M+S tires do provide better winter traction than summer tires, they generally fail to provide the same levels of cold-weather performance as winter tires.Observing speed ratingsNever exceed the maximum speed for which the winter tires are rated. <StorageStore wheels or tires in a cool, dry place, pro-tecting them from light whenever possible. Pro-tect the tires from contact with oil, grease and fuel. Do not exceed the maximum tire inflation pressure indicated on the side wall of the tire.
