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

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

Safety measures

• Park the vehicle as far away as possible from passing traffic and on solid ground.
• Turn on the hazard warning system.
• Secure the vehicle against rolling away by setting the parking brake.
• Turn the steering wheel until the front wheels are in the straight-ahead position and engage the steering wheel lock.
• Have all vehicle occupants get out of the vehicle and ensure that they remain outside the hazardous area in a safe place, such as behind a guardrail.
• If necessary, set up a warning triangle at an appropriate distance.
