PROBLEM TO BE SOLVED: To provide a method for inspecting a tire that can accurately inspect the crack resistance of a tire in a practical time.SOLUTION: The method for inspecting the crack resistance of a tire according to the present application includes: a first ozone-exposure step S3 of exposing a tire to an environment containing ozone in a higher concentration that the atmosphere does; a second ozone-exposure step S4 of exposing the tire to an environment containing ozone in a higher concentration that in Step S3; and a crack observing step S5 of observing the crack in a surface of the tire. The difference in the ozone concentration between in Step S4 and Step S3 is preferably 10pphm or higher.SELECTED DRAWING: Figure 1

    【課題】タイヤの耐クラック性が実用的な時間で精度よく検査できる検査方法の提供。【解決手段】本発明に係るタイヤの耐クラック性の検査方法は、大気よりも高い濃度のオゾンを含む雰囲気中にタイヤを晒す第一オゾン曝露工程S3、上記の工程よりも、さらに高い濃度のオゾンを含む雰囲気中にタイヤを晒す第二オゾン曝露工程S4、及びタイヤ表面のクラックを観測するクラック観測工程S5を含む。好ましくは、上記第二オゾン曝露工程S4におけるオゾン濃度と上記第一オゾン曝露工程S3におけるオゾン濃度との差は10pphm以上である。【選択図】図1
