ReferenceAt a glanceControlsDriving tipsMobility 89resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A repre-sent higher levels of performance on the laboratory test wheel than the minimum required by law. The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive load-ing, either separately or in combination, can cause heat buildup and possible tire failure.< M+SWinter and all-season tires.These have better winter properties than summer tires.Tire conditionInspect your tires frequently for treadwear, signs of damage and for foreign objects lodged in the tread. Check the tread pat-tern depth.Tire treadThe tread depth should not drop below 0.12 in/3 mm, although, for example, Euro-pean legislation only specifies a minimum tread depth of 0.063 in/1.6 mm. At tread depths below 0.12 in/3 mm, there is an increased risk of high-speed hydroplaning, even when only small amounts of water are present on the road surface.As winter tires display a noticeable loss in their ability to cope with cold-weather driv-ing conditions once the tread wears to below 0.16 in/4 mm, to ensure continued safety you should always have such tires replaced.Wear indicators at the tread-groove base, refer to arrow, are distributed over the tire's circumference and are marked on the tire sidewall with TWI - Tread Wear Indicator. At a tread depth of 0.063 in/1.6 mm these indicators, signal that the tires have reached the legally permissible wear limit.Tire damageUnusual vibrations encountered dur-ing normal vehicle operation can indi-cate tire failure or some other vehicle defect. This can, for example, be caused by driving over curbs. These kinds of prob-lems may also be signaled by other changes in vehicle response, such as a strong tendency to pull to the left or right. Should this occur, respond by immediately reducing your speed. Proceed carefully to the nearest BMW Sports Activity Vehicle Center or professional tire center, or have the vehicle towed in to have it, its wheels and tires inspected.Tire damage, extending to sudden and complete loss of pressure in extreme cases, can pose a potentially lethal safety hazard for the vehicle's occupants and other road users alike. < Replacing wheels/tiresUnprofessional attempts by laymen to service tires can lead to damage and accidents. Have this work performed by skilled pro-fessionals only. All BMW Sports Activity Vehicle Centers will be happy to help you
