2006 BMW M6 Owner's Manual - Page 175

New wheels and tires Only have new wheels and tires mounted by a BMW center or a repair shop that works in accordance with BMW guidelines and uses appropriately trained personnel. If this work is performed inexpertly, there is a danger of damage and associated safety risks. Make sure that the new wheels are balanced.< Wear indicators at the tread-groove base, refer to arrow, are distributed over the tire's circumference and are marked on the side of the tire with TWI - Tread Wear Indicator. If the tire tread has been driven down to the wear indicators, a tread depth of 0.063 in/1.6 mm has been reached. Retreaded tires BMW does not recommend the use of retreaded tires; otherwise, driving safety may be reduced. Potentially substantial variations in the design and the age of the carcasses can result in a reduced service life.< Wheel/tire damage Please note that low-profile tires cause wheels, tires and suspension parts to be more susceptible to road hazards and consequential damages. Unusual vibrations encountered during normal vehicle operation can indicate tire failure or some other vehicle defect. This can, for example, be caused by driving over curbs. These kinds of problems may also be signaled by other changes in vehicle response, such as a strong tendency to pull to the left or right. In these cases reduce your speed immediately and have the wheels and tires inspected immediately. To do this, carefully drive to the nearest BMW center or a specialized tire dealer that works in accordance with BMW guidelines and uses appropriately trained personnel. Have the vehicle towed to the repair shop if necessary. Tire damage can be extremely dangerous to vehicle occupants and other road users.< 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. When selecting the tires, also ensure that they have a sufficient load-carrying capacity. If non-approved wheels and tires are used, BMW cannot evaluate their suitability, and therefore cannot be held liable for driving safety.< You can find out the right wheel-tire combination from your BMW center. The right wheel-and-tire combination is another vital factor in ensuring reliable operation of various vehicle systems such as ABS and DSC. To maintain good handling and vehicle response, use only tires of a single tread configuration from a single manufacturer. After a tire is damaged, always remember to have the original wheel and tire combination remounted on the vehicle as soon as possible. 173 Online Edition for Part No. 01 41 0 012 118 - © 02/06 BMW AG Reference Mobility Communications Entertainment Navigation Driving tips Controls At a glance
