PROBLEM TO BE SOLVED: To provide a tire test method capable of acquiring evaluation close to evaluation to actual vehicle travel, in damage resistance to a pothole.SOLUTION: A damage test method for a tire comprises: a preparation step for preparing a tire assembly 4 in which a tire 22 is assembled to a rim, and a pothole jig 6 comprising a road surface 18 and a pothole 20 which becomes recess from the road surface 18; and a test step in which, a load is applied to the tire 22, the rim is pressed to the road surface 18 with a bead part, a side wall part and a buttress part on one side of the tire 22 in an axial direction therebetween, and a side wall part and a buttress part on the other side are inserted into the pothole 20. Preferably, in the test step, a load when a carcass cord of the tire 22 is broken, is measured.SELECTED DRAWING: Figure 1

    【課題】ポットホールに対する耐損傷性において実車走行に近い評価が得られるタイヤの試験方法の提供。【解決手段】タイヤの損傷試験方法は、タイヤ22がリムに組み込まれたタイヤ組立体4と、路面18と路面18から凹んでいるポットホール20とを備えるポットホール治具6とが準備される準備工程と、タイヤ22に荷重が負荷されてタイヤ22の軸方向一方のビード部、サイドウォール部及びバットレス部を間にしてリムが路面18に押し付けられ、他方のサイドウォール部及びバットレス部がポットホール20に挿入される試験工程とを備える。好ましくは、試験工程においてタイヤ22のカーカスコードが破断したときの荷重が測定される。【選択図】図1
