Abstract: PROBLEM TO BE SOLVED: To provide a precure tread capable of reducing biased abrasion caused by a characteristic block shape of the precure tread and a retreaded tire using it. SOLUTION: It is possible to prevent projection of a trodding part 22A of a block 22 and a kicking part 22B in the tire diametrical direction at the time of installing the precure tread on a base tire by providing a chamfering surface by cutting the trodding part 22A and the kicking part on an end part in the circumferential direction of the block 22. Consequently, it is possible to reduce grounding pressure with a road surface on the trodding part 22A and the kicking part 22B of the block 22 and to reduce biased abrasion.
