PROBLEM TO BE SOLVED: To provide an evaluation method of air fillability capable of evaluating air fillability of a tubeless tire easily in a short time.SOLUTION: An evaluation method of air fillability has a support step #1 for supporting one side wall part of a tire in a single body state, a load step #2 for imposing a load determined beforehand to the tire axial direction inside on the other side wall part of the tire, a measurement step #3 for measuring a distance between heels of a pair of bead parts in the state where the load is imposed on the other side wall part, and an evaluation step #4 for evaluating air fillability on the basis of the measured distance between heels.SELECTED DRAWING: Figure 3

    【課題】短時間かつ容易にチューブレスタイヤの空気充填性を評価できる空気充填性の評価方法を提供する。【解決手段】空気充填性の評価方法は、単体状態でのタイヤの一方のサイドウォール部を支持する支持工程#1と、タイヤの他方のサイドウォール部に、タイヤ軸方向内側へ予め定められた荷重を負荷する負荷工程#2と、他方のサイドウォール部に荷重が負荷された状態での一対のビード部のヒール間距離を測定する測定工程#3と、測定されたヒール間距離に基づいて、空気充填性を評価する評価工程#4とを有する。【選択図】図3
