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.

Repairing a flat tire
Safety measures
- Park the vehicle as far away as possible from passing traffic and on solid ground.
- Switch 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 immediate area in a safe place, such as behind a guardrail.
- If necessary, set up a warning triangle at an appropriate distance.

With the Mobility System, minor tire damage can
be sealed temporarily to enable continued travel.
To accomplish this, sealant is pumped into the
tires, which seals the damage from the inside.
