PROBLEM TO BE SOLVED: To provide a tire manufacturing method to uniformize contact pressure between a side mold and a segment during vulcanization and to improve the durability of the segment.SOLUTION: Vulcanization molding of a tire is performed in a mold-closed state in which a first abutting portion of the radially outer end of a side mold 2 and a second abutting portion of the radially inner end of a segment 3 are abutted each other. The first abutting portion includes a first abutting face 20 forming a cylindrical face concentric with a tire axis, and the second abutting face includes a second abutting face 22 forming a part of the cylindrical face concentric with the tire axis. A radius R1a at a reference temperature on the first abutting face 20 is larger than a radius R2a at the reference temperature on the second abutting face 22.SELECTED DRAWING: Figure 4 |
