BMW 3 Owners & Service Manuals

BMW 3: Tire settings

General information

The information about the mounted tires can be entered in the tire settings if the system does not automatically detect the tires.

The tire sizes of the mounted tires can be gathered from the tire inflation pressure details on the vehicle or directly on the tires.

The tire details do not need to be re-entered when the tire inflation pressure is corrected.

For summer and winter tires, the tire details entered last are stored. After a tire or wheel replacement, the settings of the tire sets used last can be selected.

Changing settings

Via iDrive:

1. "CAR".

2. "Vehicle status".

3. "Tire Pressure Monitor".

4. "Tire settings".

5. "Tire selection".

6. "Manual".

7. "Tire type".

  • "Summer tires"
  • "Winter/all-year"

8. Select the tire type that is mounted on the rear axle:

  • Tire size, e.g., 245/45 R18 96 Y.
  • For tires with special approval: "Other tire".

Observe further proceeding in the perform a reset section.

9. Select the maximum road speed that will be used with the tires.

10."Save tire settings".

The measurement of the current tire inflation pressure is started. The measurement progress is displayed.

Status display

Current status

The system status can be displayed on the Control Display, e.g., whether or not the system is active.

Via iDrive:

1. "CAR".

2. "Vehicle status".

3. "Tire Pressure Monitor".

The current status is displayed.

Current tire inflation pressure

The current tire inflation pressure is displayed for each tire.

The current tire inflation pressures may change during driving operation or depending on the external temperature.

Current tire temperature

Depending on the model, the current tire temperatures are displayed.

The current tire temperatures may change while driving or due to the external temperature.

Target pressure

The target pressure for the tires on the front and rear axles is displayed.

The specified target pressures take the influence of driving operation and external temperature on the tire temperature into account. The appropriate target pressure is always displayed, independent of the weather situation, tire temperatures and driving times.

The displayed target pressure may change and may differ from the tire inflation pressure details on the door pillar of the driver's door. The tire inflation pressure can thus be corrected to the value of the displayed target pressures.

The target pressure is immediately adjusted if the vehicle load is changed in the tire settings.

Tire conditions

General information

Tire and system status are indicated by the color of the wheels and a SMS text message on the Control Display.

Any existing messages may not be deleted if the displayed target pressure is not reached after the tire inflation pressure is corrected.

All wheels green

  • The system is active and bases warnings on the displayed target pressures.
  • For tires with special approval: the system is active and bases warnings on the tire inflation pressures stored during the last reset.

One to four yellow wheels

A flat tire or major drop in the tire inflation pressure has occurred in the indicated tires.

Gray wheels

It may not be possible to identify tire inflation pressure losses.

Possible causes:

  • Malfunction.
  • During tire inflation pressure measurement, after confirmation of the tire settings.
  • For tires with special approval: the system is being reset.

For tires with special approval: perform a reset

Via iDrive:

1. "CAR".

2. "Vehicle status".

3. "Tire Pressure Monitor".

4. Make sure that correct tire settings, refer to page 320, have been made.

5. Switch on drive-ready state and do not drive off.

6. Reset tire inflation pressure: "Perform reset".

7. Drive away.

The wheels are displayed in gray and the following is displayed "Resetting Tire Pressure Monitor...".

After a travel time of several minutes, the set tire inflation pressures are accepted as the target tire inflation pressures. The reset is completed automatically while driving.

After a successfully completed reset, the wheels on the Control Display are shown in green and the following is displayed: "Tire Pressure Monitor active. See label for recommended pressure.".

You may interrupt this trip at any time. When you continue the reset resumes automatically.
