Title: TIRE MOLD AND PNEUMATIC TIRE
Abstract:
Provided is a tire mold enabling suppression of the occurrence of bare defects in a bead section even in the production of a pneumatic tire with a reduced-size bead filler, and enabling production of a pneumatic tire having favorable adhesion with a rim. Also provided is a pneumatic tire with fewer bare defects in a bead section, favorable adhesion with the rim, and a reduced-size bead filler. The tire mold is configured so that a bead section molding surface for molding a bead section of a tire has a convex bar molding section comprising a concave groove extending in a mold radial direction, the convex bar molding section being formed in a flange contact section molding region for molding a rim flange contact section of the tire. The pneumatic tire is configured so that a tire radial direction outer end of a bead filler is positioned further inward in a tire radial direction than a rim line position and a convex bar formation section comprising a convex bar extending in the tire radial direction is formed on the outer surface of a bead section, the convex bar formation section being positioned inside a rim flange contact section.
