1. A wear amount estimation method for estimating a wear amount of an aircraft tire including a plurality of ribs in a touching down state based on information related to the aircraft, the method comprising:
calculating a shearing force of each rib of the plurality of ribs based on an average grounding pressure of the each rib;
calculating a wear energy of the aircraft tire based on the shearing force; and
estimating the wear amount of the aircraft tire based on the wear energy and a wear resistance showing a relationship between a predetermined wear amount;
wherein the information related to the aircraft includes an internal pressure of the aircraft tire, and
the average grounding pressure of the each rib is calculated based on the internal pressure and a wheel load applied to the aircraft tire.
