Abstract: A method is provided for measuring the tread or profile depth of a tire in the operating state while the tire is rolling and in contact with a surface below it. Vibrations of the tire or tire parts, which vibrations are generated by the spacing and/or geometry of profiled elements of the tire tread, are detected while the tire is rolling and in contact with the surface below it. The detected vibrations are compared in an evaluation unit with a characteristic theoretical value/threshold value that corresponds to a vibration generated by a tread of adequate depth. The evaluation unit issues a signal if the detected vibration deviates from the theoretical value/threshold value.
