BMW X3 Owners Manual: The concept
The system monitors tire inflation pressure in the four mounted tires. The system warns you if there is a significant loss of pressure in one or more tires. For this purpose, sensors in the tire valves measure the tire inflation pressure and tire temperature.

Sudden tire damage caused by external circumstances cannot be recognized in advance.
With use of the system observe further information found under Tire inflation pressure.
