BMW X5: Runflat tires

Principle

Run-flat tires permit continued driving under restricted conditions even in the event of a complete tire pressure loss.

General information

The wheels consist of tires that are self-supporting, to a limited degree, and possibly special rims.

The reinforcement of the sidewall allows the tire to remain drivable to a restricted degree in the event of a tire pressure loss.

Follow the instructions for continued driving with a flat tire.

Safety information

Warning

The vehicle handles differently when a run-flat tire has insufficient or no tire pressure; for instance, reduced lane stability when braking, braking distances are longer and the self-steering properties will change. There is a risk of accident.

Drive moderately and do not exceed a speed of 50 mph/80 km/h.

Warning

Heavy trailers can start swinging when continuing to drive with a flat tire. There may be a risk of accident or risk of damage to property. Do not exceed a speed of 35 mph/60 km/h when driving with a trailer and a flat tire. Immediately brake in the case of swinging. Apply necessary steering corrections as carefully as possible.

Identification

Wheels and tires

The tires are marked on the tire sidewall with Run-flat System Component RSC.
