TIRE MANAGEMENT DEVICE, TIRE MANAGEMENT PROGRAM, AND TIRE MANAGEMENT METHOD

A tire management device includes: a data acquiring unit 102 that acquires data D1 indicating a worn state of each tire 10 mounted on a mobile object M1 including an aircraft or a vehicle, operation data D2 of the mobile object, and internal pressure time-series data D3 of a tire; a tire change time information calculating unit 103 that calculates tire change time information d1 for responding to a state in which a remaining groove depth of the tire is less than a preset threshold value, based on the data indicating the worn state and the operation data of the mobile object; an internal pressure filling time information calculating unit 104 that calculates internal pressure filling time information d2 for responding to a state in which an internal pressure is less than a predetermined threshold value, based on transition of the internal pressure time-series data; and a maintenance instructing unit 105 that instructs whether to perform maintenance on each tire, based on the calculated tire change time information and the calculated internal pressure filling time information.
