Claims

[Scope of Claim for Utility Model Registration] In a radial tire produced by vulcanization using a 10% mold, when the seam between the sector mold and the side mold is located along the circumferential direction,
A pneumatic radial tire characterized by having a convex shape on the groove bottom of the tire lug. 2 Manufactured by a split mold consisting of a side mold that matches the tire sidewall part and a plurality of sector molds that match the tire crown part and are divided in the transverse direction at the periphery, and the radial mating surface of the side mold and sector mold is A lug located between the tread end of the tire and the maximum width of the tire and having a circumferentially continuous mating surface, the tire having a lug extending in the radial direction in an area including at least the mating surfaces of the side mold and sector mold. A plurality of grooves are arranged circumferentially at intervals, and the mating surface of the side mold and the sector mold has at least a protrusion directly facing the mating surface at a position where the mating surface crosses the bottom of the lug groove. A pneumatic radial tire.
