The invention relates to a method for adapting a tire-pressure monitoring device (1) to a vehicle type, wherein the tire-pressure monitoring device (1) is designed to be attached to a wheel of a vehicle equipped with pneumatic tires and has a device (3) for measuring the air pressure (tire pressure) in the pneumatic tire or a change of the tire pressure, possibly one or more further devices for measuring measured quantities other than the tire pressure, an electrical circuit (4), of which at least a part operates digitally, for controlling the tire-pressure monitoring device (1) and possibly for processing the measured values provided by the measuring devices (3), a memory (5, 6), in which a program for the circuit (4) is stored, an electrical power source (11) for supplying electrical power to the tire-pressure monitoring device (1), and a first transmitter (8), which operates in a first frequency range, for transmitting data from the tire-pressure monitoring device (1) to a first receiver (9) lying outside of the tire-pressure monitoring device (1), wherein initially a basic version of the program is stored in the memory (5, 6), from which basic version of the program a plurality of different versions of the program for a plurality of vehicle types can be developed, and wherein a suitable full version is produced for a selected vehicle type in that program parameters defined for the selected vehicle type are subsequently stored in the memory (5, 6) of the tire-pressure monitoring device (1).
