BMW 8 Series Convertible 2022-2023 Actions in Event of Flat Tire User Manual

Actions in the Event of a Flat Tire

Normal tires

  1. Identify the damaged tire.
    Check the tire pressure in all four tires, for instance using the tire pressure display of a flat tire kit.
    For tires with special approval: when the tire pressure in all four tires is correct, the Tire Pressure Monitor may not have been reset. In this case, perform the reset.
    If tire damage cannot be found, contact a dealer’s service center or another qualified service center or repair shop.
  2. Repair the flat tire, e.g., with a flat tire kit or by changing the wheel.
    Use of sealing compound, for instance from the flat tire kit, may damage the wheel electronics. Have the electronics replaced at the next opportunity?

Runflat tires

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

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

Follow the following when 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 tire inflation pressure in all four tires at the next opportunity.

Possible driving distance with a depressurized tire
The distance for which it may be possible to drive safely vary depending on how the vehicle is loaded and used, e.g., speed, road conditions, and outside temperature. The driving distance may be less but may also be more if an economical driving style is used. If the vehicle is loaded with an average weight and used under favorable conditions, the distance for which it may be safe to drive may be up to 50 miles/80 km.

Vehicle handling with damaged tires
Vehicles driven with a damaged tire will handle differently, potentially leading to conditions such as the following:

  • Greater likelihood of skidding of the vehicle.
    Longer braking distances.
    Changed self-steering properties.
  • Modify your driving style. Avoid abrupt steering maneuvers or driving over obstacles, for instance, curbs or potholes.
  • 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. Contact a dealer’s service center or another qualified service center or repair shop.
  • System limits
    The tire inflation pressure depends on the tire’s temperature.
    Driving or exposure to the sun will increase the tire’s temperature, thus increasing the tire inflation pressure.
    The tire inflation pressure is reduced when the tire temperature falls again.
    These circumstances may cause a warning when temperatures fall very sharply.
    Following a temperature-related warning, the target pressures are displayed on the Control Display again after a short distance.
  • Sudden tire pressure loss
    The system cannot indicate sudden serious tire damage caused by external circumstances.

Failure to perform a reset

Tires with special approval: the system will not function correctly if a reset was not performed, for example, a flat tire may be indicated although the tire inflation pressures are correct.

The yellow warning light flashes and is then illuminated continuously. A Check Control message is displayed. It may not be possible to identify tire pressure losses.


  1. A wheel without wheel electronics, such as an emergency wheel, is mounted: have the wheels checked, if needed.
  2. Fault caused by systems or devices with the same radio frequency: after leaving the area of the interference, the system automatically becomes active again.
  3. For tires with special approval: the system was unable to complete the reset. Perform a system reset again.
  4. Tire Pressure Monitor malfunction: have the system checked by a manufacturer service center or another qualified service center or repair shop.

Declaration according to NHTSA/FMVSS 138 Tire Pressure Monitoring System
Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Underinflation also reduces fuel efficiency and tire tread life and may affect the vehicle’s handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver’s responsibility to maintain correct tire pressure, even if underinflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the mal‐function exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevents the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly.
