System and method for ascertaining the emergency running condition of a pneumatic tire on a motor vehicle. The system includes at least one sensor device arranged at least on each axle, the at least one sensor device adapted to supply a permanently present first periodic oscillation proportional to a wheel rotation speed as a speed output signal, the at least one sensor device comprising one of an active and a passive magnetic field sensor being mounted to one of rotate with the tire and be stationary, the at least one sensor device further comprising one of a magnetically active and passive transmitter device which rotates at the wheel rotation speed relative to a magnetic field sensor, the transmitter device being arranged complementary to the at least one passive and active magnetic field sensor and adapted to produce a periodic magnetic field change in proportion to the wheel rotation speed in a detection range, at least one signal processing device for processing and evaluating the speed output signal, the signal processing device being adapted to produce one of an output control and a warning signal, a transmission and a display device for at least one of the transmission and the display of the speed output signal, and for one of the transmission and the display of at least one of the output control and the warning signal, and an emergency running device arranged on the vehicle wheel which, in an emergency running condition, is adapted to produce at least one separately defined periodic oscillation related to the emergency running condition and proportional to the emergency running condition wheel rotation speed, wherein, in an emergency running condition, the at least one separately defined periodic oscillation is superimposed on one of the first periodic oscillation and or the speed output signal.
