The system alerts you whenever the inflation pressure of a tire falls significantly below the pressure of another tire. In the event of tire pressure loss, the rolling radius of the tire changes, and thereby the rotational speed of the wheel. This change is detected, and a flat tire warning is issued to the driver.
