Title:
PNEUMATIC TIRE, AND TIRE MOLDING METAL MOLD
Document Type and Number:
Japanese Patent JP2018070144
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a pneumatic tire and a tire molding metal mold efficiently discharging air in tire vulcanization molding, and suppressing occurrence of vulcanization failures.SOLUTION: A pneumatic tire includes: at least one circumferential direction convex part 55 extending in the tire circumferential direction from a bead heal part to a tire radial direction outside, in an engaging surface with a rim; and a radial direction convex part 54 provided in an area from the bead heel part to a rim check line, extending in the tire radial direction, and connected to the circumferential direction convex part 55. A height of the radial direction convex part 54 is increased toward the circumferential direction convex part 55. A tire molding metal mold is a tire molding metal mold for molding the pneumatic tire, and includes a radial direction recess corresponding to the radial direction convex part 54, a circumferential direction recess corresponding to the circumferential direction convex part 55, and a vent connected to the circumferential direction recess.SELECTED DRAWING: Figure 4
