ABSTRACT:
An arrangement for monitoring the operating state of vehicle pneumatic tires (14) mounted on wheel rims (10) is provided with sensors (40, 42) for detecting the air pressure and the air temperature in each tire. Furthermore, it includes transmitting means comprising rim-side mounted rotor members (28) and bodywork-side mounted stator members (32) coupled thereto for transmitting the parameters detected by the sensor (40, 42) to an evaluating arrangement in the vehicle connected to the stator members. The pressure sensor (40) and the temperature sensor (42) of each tire (14) are coupled to a first transponder (44) which as reaction to an interrogation signal generated by the evaluating arrangement transmits the data supplied to it by the pressure sensor (40) and the temperature sensor (42) to the rotor members (28) of the transmitting means. Disposed in the pneumatic tire (14) is a second transponder (48) which when it receives the interrogation signal transmits data designating the type of the pneumatic tire (14) to the stator members (32).
