Provided is a retreaded tire that uses cushion rubber for retread that is able to further improve the prevention of separation failure while effectively suppressing blowout within the cushion rubber layer. The retreaded tire includes cushion rubber for retread, a base tire, and precured tread rubber formed of at least one rubber layer, and is characterized by: the aforementioned cushion rubber for retreaded tires being formed from a rubber composition containing specific quantities of a highly reinforcing carbon black of at least HAF grade, and natural rubber and/or synthetic polyisoprene rubber; the 100% modulus (AM) of the rubber layer (A) that comprises the aforementioned cushion rubber for retread being at least 3.0 MPa and less than 6.0 MPa; and the outermost layer (B) of the aforementioned base tire and the innermost layer (C) of the aforementioned precured tread rubber being formed from a rubber composition containing specific quantities of natural rubber and/or synthetic polyisoprene rubber.
