PROBLEM TO BE SOLVED: To provide a pneumatic tire in which the deterioration degree thereof can be simply determined, and to provide a tire deterioration-determining method and a method for determining tire reclamation possibility.SOLUTION: A pneumatic tire in this invention is equipped with a tire deterioration-determining tool 10 comprising the molded body 11 of a rubber composition. The tire deterioration-determining tool 10 is loaded on a tire inner face S in such a state that an initial strain is imparted. A breaking state of the tire deterioration-determining tool 10 is checked at an optional time point after tire use start, and the deterioration degree of the tire is determined on the basis of the breaking state. Besides, the breaking state of the tire deterioration-determining tool 10 is checked at tire reclamation, and the reclamation possibility of the pneumatic tire is determined based on the breaking state.SELECTED DRAWING: Figure 1

    【課題】 タイヤの劣化度合いを簡単に判定することを可能にした空気入りタイヤ、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】 本発明の空気入りタイヤは、ゴム組成物の成形体11からなるタイヤ劣化判定具10を備え、該タイヤ劣化判定具10は初期歪が与えられた状態でタイヤ内面Sに装着される。タイヤ使用開始後の任意の時点でタイヤ劣化判定具10の破断状態を確認し、その破断状態に基づいて空気入りタイヤの劣化度合いを判定する。また、タイヤ更生時にタイヤ劣化判定具10の破断状態を確認し、その破断状態に基づいて空気入りタイヤの更生可否を判定する。【選択図】図1
