PROBLEM TO BE SOLVED: To enhance measurement accuracy of rolling resistance and its reliance.SOLUTION: A tire rolling resistance test method comprises: a rolling resistance measuring step S2 for measuring axial force Fx in a tangential direction generated on a tire shaft 3 when a tire T is rotated in a loaded state, using a component meter 6; and a determining step S3 for measuring axial force FxA in a stopping state without load when the tire T is separated from a drum 2, comparing the axial force FxA with a threshold KA, and determining that a result of the test is abnormal when the axial force FxA exceeds the threshold KA.

    【課題】転がり抵抗の測定精度、及びその信頼性を高める。【解決手段】タイヤTを負荷状態にて回転させたときにタイヤ軸3に発生する接線方向の軸力Fxを分力計6を用いて測定する転がり抵抗測定工程S2と、タイヤTをドラム2から離間させた無負荷の停止状態にて軸力FxAを測定し、該軸力FxAを閾値KAと比較するとともに閾値KAを越えた場合に試験を異常と判定する判定工程S3とを具える。【選択図】図3
