BMW 3: Run-flat tires
Concept
Run-flat tires permit continued driving under restricted conditions even in the event of a complete loss of tire inflation pressure.
General information
The wheels consist of tires that are self-supporting, to a limited degree, and possibly special rims.
The support of the sidewall allows the tire to remain drivable to a restricted degree in the event of a tire inflation pressure loss.
Follow the instructions for continued driving with a flat tire.
Safety information
Warning Your vehicle handles differently with a run-flat tire with no or low inflation pressure; for instance, your lane stability when braking is reduced, 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.

- 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 immediate area in a safe place, such as behind a guardrail.
- If necessary, set up a warning triangle at an appropriate distance.
