PROBLEM TO BE SOLVED: To provide a regenerated tire configured so that occurrence of a detachment and a crack of an end part of a tread for the regenerated tire can be reduced.SOLUTION: The regenerated tire comprises a base tire 20 and a tread 2 for a regenerated tire arranged at buff parts 40 of the base tire 20. The buff parts 40 have a tread-side buff surface 41 positioned on an outer peripheral surface of the base tire 20 and a buttress part-side buff surface 42 extending from end parts at both sides in a tire width direction of the tread-side buff surface 41 toward inside in a tire radial direction. In the tread 2 for the regenerated tire, an end part 4 of the tread for the regenerated tire, an end part in a tire width direction is positioned on the buttress part-side buff surface 42. The buttress part-side buff surface 42 has an uneven part 50, in which a recessed part 51 and a protruding part 53 which vibrate in the tire width direction are arranged in the tire radial direction and the recessed part 51 and the protruding part 53 extend in a tire circumferential direction, in a concentric circular shape or a spiral shape with the tire rotating shaft as a center. The uneven part 50 has at least a pair of the recessed parts 51 and a pair of the protruding parts 53 at any position in the tire circumferential direction.SELECTED DRAWING: Figure 2

    【課題】更生トレッドの端部の剥離やクラックの発生を低減することのできる更生タイヤを提供すること。【解決手段】台タイヤ20と、台タイヤ20のバフ部40に配設される更生トレッド2と、を備え、バフ部40は、台タイヤ20の外周面に位置するトレッド側バフ面41と、トレッド側バフ面41のタイヤ幅方向における両側の端部からタイヤ径方向内方側に延在するバットレス部側バフ面42と、を有し、更生トレッド2は、タイヤ幅方向における端部である更生トレッド端部4がバットレス部側バフ面42上に位置しており、バットレス部側バフ面42は、タイヤ幅方向に振幅する凹部51と凸部53とがタイヤ径方向に並ぶと共に、凹部51と凸部53とがタイヤ回転軸を中心とする同心円状または渦巻き状にタイヤ周方向に延びる凹凸部50を有しており、凹凸部50は、タイヤ周方向におけるいずれの位置においても凹部51と凸部53とを少なくも一対ずつ有する。【選択図】図2
