PROBLEM TO BE SOLVED: To provide a tire deterioration-determining tool capable of determining the deterioration degree of a pneumatic tire in detail by enhancing the discrimination sensitivity of the tool, and to provide a pneumatic tire equipped with the above tool, a tire deterioration-determining method and a method for determining tire reclamation possibility.SOLUTION: A tire deterioration-determining tool 10 comprising the molded body of a rubber composition is configured so that the ratio S/V of a surface area S (mm) of a portion of the molded body 11 excluding a loaded surface to the volume V (mm) of the molded body 11 is 0.1 or more, and the above surface area S is 50 mmor more. Such like tire deterioration-determining tool 10 is loaded on a tire inner face.SELECTED DRAWING: Figure 1
【課題】 タイヤ劣化判定具から識別される劣化度合いの感度を高め、空気入りタイヤの劣化度合いを詳細に判定することを可能にしたタイヤ劣化判定具、タイヤ劣化判定具を備えた空気入りタイヤ、タイヤ劣化判定方法及びタイヤ更生可否判定方法を提供する。【解決手段】 ゴム組成物の成形体からなるタイヤ劣化判定具10であって、成形体11の被装着面を除く部分の表面積S(mm2)と成形体11の体積V(mm3)との比S/Vを0.1以上とし、成形体11の被装着面を除く部分の表面積Sを50mm2以上とする。このようなタイヤ劣化判定具10をタイヤ内面に装着する。【選択図】図1
