Abstract: A method for manufacturing a tire having a sidewall portion provided with a projecting marking is disclosed. A stencil plate for molding the projecting marking is made of a thin metallic plate whose thickness is 0.2 to 0.8 mm and mounted in a recess formed in a sidewall molding surface of the tire vulcanization mold. A concave marking part for molding the projecting marking is formed by press working upon the metallic plate. Edge portions of the stencil plate are turned back. The backward extension H2 of the turnback is substantially the same as the depth of the concave marking part.
