Abstract: A tire manufacturing method in which a vulcanizing mold (20) is provided with a tire molding portion (21) defining an outer surface shape of a tire (1), an extrusion preparing portion (22) in which an unvulcanized rubber member (5) that forms a tread portion (2) can be disposed, and a rubber inflow path (23) communicating between the tire molding portion (21) and the extrusion preparing portion (22), wherein vulcanization molding includes: loading a casing member (4) in the tire molding portion (21) and loading the unvulcanized rubber member (5) in the extrusion preparing portion (22); extruding the unvulcanized rubber member (5) to tread molding portions (21c), (21d) through the rubber inflow path (23), the tread molding portions formed in the tire molding portion (21) and defining an outer surface shape of a land portion of the tire; and vulcanizing the unvulcanized rubber member (5) and casing member (4) together.
