PROBLEM TO BE SOLVED: To provide a method of estimating the wear of a tire, capable of improving estimation accuracy.SOLUTION: A method of estimating the wear of a tire includes the steps of: preparing a test tire which can rotate about a center shaft, and has a first tread surface, a second tread surface disposed adjacently to the first tread surface in a circumferential direction of the center shaft, and a lateral groove provided between the first tread surface and the second tread surface and including a lag groove or a sipe; measuring the friction energy of a first measurement part defined on the first tread surface; measuring the friction energy of a second measurement part defined on the second tread surface; and estimating the heel and tow wear of the test tire, on the basis of difference between the friction energy of the first measurement part and the friction energy of the second measurement part.SELECTED DRAWING: Figure 6

    【課題】予測精度を向上できるタイヤの摩耗予測方法を提供する。【解決手段】タイヤの摩耗予測方法は、中心軸を中心に回転可能であり、第1トレッド表面と、中心軸の周方向に関して第1トレッド表面の隣に配置される第2トレッド表面と、第1トレッド表面と第2トレッド表面との間に設けられラグ溝又はサイプを含む横溝と、を有する試験タイヤを準備することと、第1トレッド表面に定められた第1測定部位の摩擦エネルギーを測定することと、第2トレッド表面に定められた第2測定部位の摩擦エネルギーを測定することと、第1測定部位の摩擦エネルギーと第2測定部位の摩擦エネルギーとの相違に基づいて、試験タイヤのヒールアンドトゥ摩耗を予測することと、を含む。【選択図】図6
