PROBLEM TO BE SOLVED: To provide a tire characteristics measurement method for precisely evaluating characteristics of a tire in which blocks are formed on a tread section.SOLUTION: A tire characteristics measurement method evaluates characteristics of a tire 2 in which blocks 11 are formed on a tread section 10, and includes: a travel process S2 for mounting the tire 2 onto a vehicle 3 to travel on a test path C; a measurement process S3 for measuring information I of the vehicle 3 and tire 2 during travel; and a calculation process S4 for calculating a frictional coefficient μ and a slip ratio s between the tire 2 and the test path C based on the measured information I. In the calculation process S4, the frictional coefficient μ and the slip ratio s are calculated for a plurality of touch-down moments at which a touch-down state of blocks 11 in a rotation direction R of the tire relative to the test path C is different.SELECTED DRAWING: Figure 1

    【課題】トレッド部にブロックが形成されたタイヤの特性を精度よく評価するためのタイヤ特性計測方法を提供する。【解決手段】トレッド部10にブロック11が形成されたタイヤ2の特性を評価するための方法である。タイヤ2を車両3に装着して試験路Cで走行させる走行工程S2と、走行中の車両3及びタイヤ2の情報Iを測定する測定工程S3と、測定された情報Iに基づいて、タイヤ2と試験路Cとの間の摩擦係数μ及びスリップ率sを計算する計算工程S4とを含んでいる。計算工程S4は、試験路Cに対するブロック11のタイヤ回転方向Rの接地状態が異なる複数の接地瞬間について、摩擦係数μ及びスリップ率sを計算している。【選択図】図1
