To evaluate vibration characteristics of a tire.SOLUTION: A method for evaluating vibration characteristics of a tire includes a first step S1 of causing a vehicle to which a tire is mounted to perform normal circle turning traveling at predetermined limit speed of a turning radium, a second step S2 of, following the first step S1, causing the vehicle to travel with speed equal to or faster than the limit speed and a steering angle of a steering wheel of the vehicle larger than that in the first step S1, a third step S3 of acquiring a parameter for vibration characteristics of a vehicle 1 in the second step S2, and a fourth step S4 of determining quality of the vibration characteristics on the basis of the parameter.SELECTED DRAWING: Figure 1

    【課題】タイヤの振動特性を評価する。【解決手段】タイヤの振動特性の評価方法である。タイヤが装着された車両を、予め定められた旋回半径の限界速度で定常円旋回走行させる第1工程S1と、第1工程S1に引続き、車両を、限界速度以上の速度、かつ、車両のハンドルの操舵角を第1工程S1時の操舵角よりも大きくして走行させる第2工程S2と、第2工程S2での車両1における振動特性に関するパラメータを取得する第3工程S3と、前記パラメータに基づいて、振動特性の良否を判定する第4工程S4とを含む。【選択図】図1
