PROBLEM TO BE SOLVED: To increase the speed of adhesion reaction at an interface between a thermosetting resin and an adhesive to enhance cohesion at the interface.SOLUTION: A method for manufacturing an airless tire includes the steps of: adhesive application S2 applying an adhesive on an inner circumferential surface 2S of a cured tread ring 2 to form an adhesion layer 21; mounting S4 mounting the tread ring 2 applied with the adhesion layer 21 and a hub 3 into a cast mold 30; and cast molding S5 pouring a raw material liquid of a thermosetting resin into the cast mold 30 and curing. Prior to the step of mounting S4, a step of preheating S3 preheating the tread ring 2 applied with the adhesion layer 21 is carried out.SELECTED DRAWING: Figure 6 【課題】 熱硬化性樹脂と接着剤との界面での接着反応の速度を早めて、界面での結合力を高める。【解決手段】 加硫されたトレッドリング２の内周面２Ｓに、接着剤を塗布して接着層２１を形成する接着剤塗布工程Ｓ２、接着層２１が塗布されたトレッドリング２とハブ３とを注型金型３０内に装着する装着工程Ｓ４、及び注型金型３０内に熱硬化性樹脂の原料液を注入かつ硬化させる注型成形工程Ｓ５を具える。装着工程Ｓ４に先駆け、接着層２１が塗布されたトレッドリング２を予熱する予熱工程Ｓ３を行う。【選択図】図６
