Provided is a retreaded tire comprising a base tire, a tread member, and an adhesive layer, wherein the adhesive layer is arranged between the base tire and the tread member, wherein the tread member is composed of a rubber composition, wherein the adhesive layer is composed of a resin-based adhesive, and wherein a value of 70° C. tan δ×(Tc/Ta) is 4.00 or more, where Tc represents a thickness, in mm, of the tread member, Ta represents a thickness, in mm, of the adhesive layer, and 70° C. tan δ represents a loss tangent at 70° C. of the rubber composition. Deterioration of ride comfort is suppressed while using the resin-based adhesive.
