PROBLEM TO BE SOLVED: To provide a precure tread and a recapped tire capable of improving low heat generation at running time after recapped. SOLUTION: In a precure tread 3 having a tread pattern of rib base tune in a tread surface, in a bonding surface relating to a base tire 1, molded rough surfaces 7a, 7b formed by irregularity are formed, a depth of the irregularity of the molded rough surface 7a in both shoulder parts is set deeper than of the molded rough surface 7b in a region except both the shoulder parts. The precure tread 3 is fixed to a peripheral surface of the base tire 1 through a cushion rubber 2, as the cushion rubber 2, a rubber of heat generation lower than a rubber constituting the precure tread 3 is used. |
