Title:
METHOD FOR PRODUCING PNEUMATIC TIRES, TIRE MOLD, AND PNEUMATIC TIRES
Document Type and Number:
WIPO Patent Application WO/2018/194081
Kind Code:
A1
Abstract:
A replaceable member having a smooth flat surface is attached to a mold body portion of a tire mold that is brought into contact with an unvulcanized tire to vulcanize the unvulcanized tire into a prescribed shape when producing a pneumatic tire, thereby forming a mold inner surface that creates the shape of a tire side surface portion including the curved surface of the mold body portion and the flat surface surrounded by the curved surface. A vulcanized tire is then produced by bringing the unvulcanized tire into contact with the mold inner surface and vulcanizing. Furthermore, a two-dimensional code, in which a dot pattern is formed by two kinds of shading elements formed so as to be distinguishable from each other by protrusions/recesses on the surface, is inscribed in a planar region that corresponds to the flat surface of the vulcanized tire.
