Abstract
A method for manufacturing a tire T comprises a step for forming a green tire on the outside of a rigid core mold 2, a step for vulcanization-molding and obtaining a tire-accompanying rigid core mold G, a step for setting, at an assembly station P3, a core 5 taken out from the tire-accompanied rigid core mold G, and a removal and assembly step for removing one core segment 3 from the tire T by moving in inwardly in the tire radial direction from the tire-accompanying rigid core mold G and mounting it on the core 5 set at the assembly station. The removal and assembly step is performed for every core segment in the tire, whereby a rigid core mold 2 is assembled at the assembly station P3, while removing the rigid core mold 2 from the tire T.
