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 plurality of grooves having same or similar design patterns disposed in a circumferential direction; defining evaluation partitions for the test tire based on at least one of a pitch and a block; setting a first measurement point in an evaluation partition in a first-come region; setting a second measurement point in an evaluation partition in a second-come region; 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、同一の又は類似するデザインの溝パターンが周方向に複数設けられた試験タイヤを準備することと、ピッチ及びブロックの少なくとも一方に基づいて、試験タイヤの評価区画を規定することと、評価区画の先着領域に第1計測点を設定することと、評価区画の後着領域に第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
