Abstract
A wear amount estimation method calculates a shearing force of each rib based on an average grounding pressure of each rib of an aircraft tire; calculates a wear energy of the aircraft tire based on the shearing force; and estimates the wear amount of the aircraft tire based on the wear energy and a wear resistance showing a relationship between a predetermined wear amount. The information related to the aircraft includes an internal pressure of the aircraft tire. The average grounding pressure of each rib is calculated based on the internal pressure and a wheel load applied to the aircraft tire.
