A process for checking the air pressure in the tires of motor vehicle wheels wherein at least a pressure signal characteristic for the air pressure will be picked up as a measured signal by a measurement device located in or on the tire of each motor vehicle wheel, wherein at least. a data signal containing a measured air pressure value derived from the pressure signal as well as an identification value characteristic for the respective transmitter device will be generated and output by a transmitter device located in or on the tire of each motor vehicle wheel, wherein the data signal output by the transmitter devices will be received by a reception device located at a distance to the motor vehicle wheels, and wherein the identification value of the transmitter device contained in the data signal will be compared by a control unit to identification comparison values assigned to the respective transmitter devices such that further processing of the data signal by the control unit will be effected only, if the identification value and the identification comparison value meet a specified assignment criterion.
