PROBLEM TO BE SOLVED: To suppress the peeling between a tread ring and a spoke caused by the thermal shrinkage of a polymer material upon cast molding.SOLUTION: Provided is a method for producing an airless tire comprising a tread vulcanization process K2 where a raw tread ring 2R formed on a tread formation face 10s of a rigid core 10 is charged inside a vulcanization die 12 including the rigid core 10, and heat vulcanization is performed. By providing the tread formation face 10s with a plurality of strip grooves 11 stretching from one side edge side in an axial core direction to the other side edge side, a projecting strip 5 with strip grooves 11 transferred is formed at the inner circumferential face of the vulcanization tread ring 2.SELECTED DRAWING: Figure 5

    【課題】 注型成形時の高分子材の熱収縮に起因するトレッドリングとスポークとの剥離を抑制する。【解決手段】 剛性中子10のトレッド形成面10s上で形成した生トレッドリング2Rを、剛性中子10ごと加硫金型12内に投入して加熱加硫するトレッド加硫工程K2を有する。トレッド形成面10sに、軸心方向の一側縁側から他側縁側にのびる複数本の条溝11を具えることにより、既加硫トレッドリング2の内周面に、条溝11が転写された凸条5を形成する。【選択図】図5
