1. Method for detecting a pressure loss in tires in a motor vehicle during travel, especially for detecting the dropping of the pressure below a definable threshold value (critical tire pressure), by evaluating sensor determined angular velocities of the wheels of the motor vehicle or evaluating informations, which indicate the angular velocities on the basis of time intervals, characterized in that the pressure loss detection method includes two or more submethods (Prog A, Prog B, Prog S, Prog V) which are each by themselves a separately operable method for measuring the pressure in a motor vehicle tire or for detecting a critical tire pressure, the steps of the submethods being carried out in parallel or quasi parallel.
