A tire pressure monitoring device for a vehicle having several wheels comprises a central receiving and evaluation device at the vehicle. Each a receiving antenna (A, B, C, ... N) is arranged stationarily at the vehicle structure adjacent to at least each active wheel and thus attributed to said specific wheel. All said receiving antennas (A, B, C, ... N) being connected via each a distinctive connecting line (a, b, c, ... n) with a single receiver means. Said receiver means comprises a multiplexer-circuit connecting per time interval only one single selected receiving antenna or several selected receiving antennas with said receiving means. Further, said receiver means sensing a field strength of each specific radiogram and thus selecting said specific receiving antenna comprising the highest field strength of a received radiogram during said specific time interval. Thus, central evaluation means may attribute a specific radiogram to said specific wheel being arranged adjacent to said receiving antenna comprising the highest field strength of a received radiogram during said specific time interval.
