Method for obtaining information about tires on a vehicle includes arranging a tire monitor on each tire, arranging an interrogator on the vehicle, arranging antennas on the vehicle, each antenna being spaced apart from one another and associated with some tires and further being spaced different distances from the tire monitors on the associated tires, wirelessly transmitting initiation signals from the interrogator to each tire monitor through the antennas to cause each tire monitor to provide signals containing information about one or more properties of the tire on which the tire monitor is arranged, receiving the signals provided by the tire monitors at the antennas, directing the signals from the antennas to the interrogator, and determining a location of each tire monitor and thus a location of a tire on which the tire monitor is arranged by analyzing the signals provided by each tire monitor.
