摘要： A tire mold has a tire molding surface. The tire molding surface is pressed against an outer surface of an uncured tire. A vent hole is provided in the tire molding surface. A surface of an outer edge region surrounding an opening of the vent hole is formed by a smooth surface. The smooth surface is smoother than a surface in a peripheral region of the outer edge region.

摘要： A pneumatic tire having improved wear resistance, especially improved uneven wear resistance (such as river wear), is offered. The tire that is a rib-pattern tire has five ribs extending circumferentially of the tire. The ribs include a center rib and intermediate ribs located on the opposite sides of the center rib that is located on the equator line of the tire. Closed sipes are formed at least in the center rib and in the intermediate ribs. Each sipe is located in the lateral center of the corresponding rib. Both ends of each sipe terminate within the corresponding rib. The closed sipes are successively offset circumferentially among the ribs and arranged in a periodic pattern on the outer surface of the tire. The closed sipes in the ribs are so arranged that when they are optically projected onto the equator line of the tire, the sipes do not overlap circumferentially of the tire among the ribs.
