BMW X3 Owners Manual: Actions in the event of a flat tire

Normal tires

1. Identify the damaged tire.

Do this by checking the air pressure in all four tires.

If the tire inflation pressure in all four tires is correct, the Tire Pressure Monitor may not have been initialized. In this case, initialize the system.

If an identification is not possible, please contact the service center.

2. Rectify the flat tire on the damaged wheel.

Use of tire sealant, e.g., the Mobility System, may damage the TPM wheel electronics. In this case, have the electronics checked at the next opportunity and have them replaced if needed.

Run-flat tires

Maximum speed You may continue driving with a damaged tire at speeds up to 50 mph/80 km/h.

Continued driving with a flat tire If continuing to drive with a damaged tire:

1. Avoid sudden braking and steering maneuvers.

2. Do not exceed a speed of 50 mph/80 km/h.

3. Check the air pressure in all four tires at the next opportunity.

If the tire inflation pressure in all four tires is shown to be correct, it is possible that the Tire Pressure Monitor did not perform a reset. In that case, carry out a reset.

Possible driving distance with complete loss of tire inflation pressure: The possible driving distance after a loss of tire inflation pressure depends on cargo load, driving style and road conditions.

A vehicle with an average load has a possible driving range of approx. 50 miles/80 km.

A vehicle with a damaged tire reacts differently, e.g., it has reduced lane stability during braking, a longer braking distance and different self-steering properties. Adjust your driving style accordingly. Avoid abrupt steering maneuvers or driving over obstacles, e.g., curbs, potholes, etc.

Because the possible driving distance depends on how the vehicle is used during the trip, the actual distance may be shorter or longer depending on the driving speed, road conditions, external temperature, cargo load, etc.

Continued driving with a flat tire

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

Your car handles differently when you lose tire inflation pressure, e.g., your lane stability is reduced when braking, braking distances are longer and the self-steering properties will change.

Final tire failure

Vibrations or loud noises while driving can indicate the final failure of a tire. Reduce speed and stop; otherwise, pieces of the tire could come loose and cause an accident. Do not continue driving and contact your service center.
