With proper use, these tires meet the highest standards for safety and handling characteristics. Snow chains* BMW only tests certain fine-link snow chains, classifies them as road-safe and recommends them. Consult your BMW center for more information. These snow chains are approved exclusively for use in pairs on the rear wheels with the tire size: > 245/50 R 17 Y > 245/45 R 18 Y Observe the manufacturer's instructions when mounting snow chains. Do not exceed a speed of 30 mph/50 km/h with the chains mounted. Do not initialize the Flat Tire Monitor after installing snow chains as this could cause the Flat Tire Monitor to malfunction. When driving with snow chains, it may be practical to briefly activate DTC, refer to page 88.< Run-flat tires When installing new tires or when changing from summer tires to winter tires, for your own safety, use run-flat tires. No spare wheel is provided in the event of a flat. Your BMW center will be glad to advise you. For safety reasons, BMW recommends that you do not have damaged run-flat tires repaired; they should be replaced.< Special characteristics of winter tires BMW recommends winter tires for use in cold winter driving conditions. Although all-season M+S tires provide better winter traction than summer tires, they generally fail to provide the same levels of cold-weather performance as winter tires. Watch speed Always observe the maximum permissible speed for the winter tires, otherwise tire damage may occur, which can result in accidents.< Storage Store wheels and tires in a cool, dry place with as little exposure to light as possible. Always protect tires against all contact with oil, grease and fuels. Do not exceed the maximum tire inflation pressure indicated on the side wall of the tire. Rotating wheels between axles BMW does not recommend moving the front wheels to the rear or vice versa, as otherwise the handling characteristics may be impaired. 205 Online Edition for Part no. 01 41 0 013 312 - © 02/07 BMW AG Reference Mobility Communications Entertainment Navigation Driving tips Controls At a glance
