PROBLEM TO BE SOLVED: To highly reliably evaluate a tire.SOLUTION: A tire evaluation method includes: a running step of causing a vehicle 51 mounted with pneumatic tires 53a, 53b to run at a constant ground speed along a preset running route; a sensory evaluation step of sensorily evaluating a steering feel obtained from a steering system 52 of the vehicle 51 in the running step; an acceleration measuring step of measuring the lateral acceleration generated in the vehicle 51 in the running step; a steering effort measuring step of measuring a steering effort in the steering system 52 of the vehicle 51 in the running step; a performance characteristic value acquiring step of acquiring a performance characteristic value at the time when the steering effort is null from the lateral acceleration and the litharge waveform of the steering effort measured in the steering effort measuring step; and a lateral spring constant setting step of setting a lateral spring constant in the single bodies of the pneumatic tires 53a, 53b corresponding to the optimal value of the performance characteristic value led from the relationship with the steering feel in the sensory evaluation step.

    【課題】信頼性の高い評価を行うこと。【解決手段】空気入りタイヤ53a,53bが装着された車両51を予め定められた走行ルートに沿って一定の対地速度で走行させる走行工程と、走行工程において車両51の舵取装置52から得られる操舵感を官能評価する官能評価工程と、走行工程において車両51に生じる横向加速度を計測する加速度計測工程と、走行工程において車両51の舵取装置52における操舵力を計測する操舵力計測工程と、加速度計測工程で計測された横向加速度および操舵力計測工程で計測された操舵力のリサージュ波形から操舵力ゼロ時の性能特性値を取得する性能特性値取得工程と、官能評価工程における操舵感との関係性から性能特性値の最適値を導き、当該性能特性値の最適値に対応する空気入りタイヤ53a,53b単体における横バネ定数を設定する横バネ定数設定工程と、を含む。【選択図】図1
