PROBLEM TO BE SOLVED: To provide a tire valve ID registration system capable of easily registering a spare tire ID in a receiver without using a registration tool.SOLUTION: A spare tire ID collection part 20 collects valve IDs as candidate IDs for a spare tire 2e which are included in a radio wave Sva received on a condition that the radio wave Sva can be determined to be sent from the spare tire 2e in a provisional registration period. The condition that the radio wave Sva can be determined to be sent from the spare tire 2e means that a tire valve 4 sends the radio wave Sva including stop information Dst even when a vehicle 1 is running. A spare tire ID determination part 21 determines a specific valve ID as an ID for the spare tire 2e from among collected candidate IDs by repeatedly operating a phase during a subsequent official registration period, and narrowing down a valve ID which can continuously be received in the subsequent period on the condition that the radio wave Sva can be determined to be sent from the spare tire 2e. |
