Claim:
1. A tire position determination system comprising: tire pressure transmitters respectively arranged in tires, each tire pressure transmitter being capable of transmitting a first radio wave that includes pressure data and a tire ID of a corresponding tire and a second radio wave indicating that the tire pressure transmitter has reached a specific position on a tire rotation path of the corresponding tire; a receiver arranged on a vehicle and capable of receiving the first radio wave and the second radio wave from each of the tire pressure transmitters; axle rotation detectors respectively arranged on axles, each axle rotation detector being capable of detecting rotation of a corresponding axle to output axle rotation information; and a controller configured to monitor pressure of each tire based on the first radio wave received by the receiver, wherein the controller includes: specifying a tire that rotates in synchronism with the axle rotation information of each axle to associate the tire ID of each tire with one of the axles;
