To provide a method capable of evaluating the turning performance, especially limit turning performance of a tire.SOLUTION: Provided is a method for evaluating the turning performance of a tire. The method includes the steps of: mounting a tire on a vehicle and causing the vehicle to make a turning travel; acquiring multiple times data of longitudinal acceleration and data of lateral acceleration generated in the vehicle during travel; creating, by a computer, a friction circle 7 by using the longitudinal acceleration data and the lateral acceleration data; calculating, by the computer, the area inside the contour 8 of the friction circle 7; and outputting, by the computer, the area.SELECTED DRAWING: Figure 7

    【課題】 タイヤの旋回性能、とりわけ限界旋回性能を評価することが可能な方法を提供する。【解決手段】 タイヤの旋回性能を評価するための方法である。タイヤを車両に装着して、車両を旋回走行させる工程と、走行中の車両に生じる前後加速度データ及び横加速度データを複数回取得する工程と、コンピュータが、前後加速度データ及び横加速度データを用いて摩擦円7を作成する工程と、コンピュータが、摩擦円7の輪郭8内の面積を計算する工程と、コンピュータが、面積を出力する工程とを含む。【選択図】図7
