PROBLEM TO BE SOLVED: To provide a tire wear evaluation method capable of accurately evaluating a wear state of a tire after an actual travel.SOLUTION: A tire wear evaluation method comprises: providing a test tire including a first tread surface, a second tread surface arranged adjacent to the first tread surface in a circumferential direction, a lateral groove disposed between the first and second tread surfaces and including lug grooves and sipings; setting a first measurement point on the first tread surface; setting a second measurement point on the second tread surface; setting a reference point for measurement; measuring a distance between the first measurement point and the reference point; measuring a distance between the second measurement point and the reference point; calculate a level difference amount between levels at the first and second measurement points based on a difference between the distance from the first measurement point to the reference point and the distance from the second measurement point to the reference point; and evaluating a circumferential-direction eccentric wear characteristic of the test tire based on the calculated level difference amount.SELECTED DRAWING: Figure 6
【課題】実際に走行した後のタイヤの摩耗状態を的確に評価できるタイヤの摩耗評価方法を提供する。【解決手段】タイヤの摩耗評価方法は、第1トレッド表面と、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トレッド表面に第1計測点を設定することと、第2トレッド表面に第2計測点を設定することと、計測における基準点を設定することと、第1計測点と基準点との距離を計測することと、第2計測点と基準点との距離を計測することと、第1計測点と基準点との距離と第2計測点と基準点との距離との相違に基づいて、第1計測点と第2計測点との段差量を算出することと、算出された段差量に基づいて、試験タイヤの周方向偏摩耗性能を評価することと、を含む。【選択図】図6
