A tire position registration system is provided with a position determination unit (21) that acquires a plurality of pieces of axle rotation information respectively from a plurality of axle rotation detection units (19) each time radio waves from a tire valve (4) are received by a receiver (12). The position determination unit (21) has a plurality of synchronized wheel allowable ranges that are set in one period of one piece of axle rotation information corresponding to one rotation of one axle. The position determination unit (21), each time the radio waves from the tire valve (4) are received by the receiver (12), determines in which of the plurality of synchronized wheel allowable ranges each of the plurality of pieces of axle rotation information is included, and identifies, based on the result of the determination, the ID of the tire valve of the tire that rotates in synchronism with the axle rotation information of each of a plurality of axles, so as to determine the tire position of a plurality of tires by associating the ID of the tire valve (4) and the axles. |
