ABSTRACT:
System and method of detecting an onset of tread rubber separation of a pneumatic tire on a vehicle, in which a permanent first periodic vibration is produced, in at least one of each axle and each wheel, that is proportional to a wheel rotational speed as a speed output signal. The speed output signal is fed to a signal processing device, wherein in the onset of tread rubber separation, there is provided the superimposition on a first vibration or the speed output signal, at least one separately defined periodic vibration characteristic of the onset of tread rubber separation and proportional to the wheel rotational speed. The superimposition of the first periodic vibration with the at least one separately defined periodic vibration characteristic of the onset of tread rubber separation is detected in the signal processing device and a warning signal is produced.
