PROBLEM TO BE SOLVED: To provide a performance evaluation method of a tire for evaluating performance of the tire quantitatively using a vehicle.SOLUTION: A method for evaluating the performance of a tire 2 includes a travel step S1 of holding the tire 2 to a vehicle 1 and making the vehicle 1 travel on a road surface R, an imaging step S2 of acquiring a plurality of images Im of the tire 2 during travel in association with predetermined time tof the travel step S1, an acceleration acquisition step S5 of determining rotational acceleration Ta of the tire 2 during travel from the time tin a time-sequence manner, an extraction step S6 of extracting an image Imn imaged when the rotational acceleration Ta reaches a predetermined value TS from among the images Im and a calculation step S7 of calculating deformation state of the tire 2 on the basis of the extracted image Imn.SELECTED DRAWING: Figure 2

    【課題】車両を用いてタイヤの性能を定量的に評価するためのタイヤ性能評価方法を提供する。【解決手段】タイヤ2の性能を評価するための方法である。タイヤ2を車両1に装着し、車両1を、路面R上で走行させる走行工程S1と、走行工程S1の予め定められた時刻t0に関連付けて、走行中のタイヤ2の複数の画像Imを取得する撮像工程S2と、時刻t0から、走行中のタイヤ2の回転加速度Taを時系列的に求める加速度取得工程S5と、画像Imの中から、回転加速度Taが予め定められた値TSとなるときに撮像された画像Imnを抽出する抽出工程S6と、抽出された画像Imnに基づいて、タイヤ2の変形状態を計算する計算工程S7とを含んでいる。【選択図】図2
