ABSTRACT:
A tire vulcanizing mold is divided into an upper-mold and a lower-mold in the tire axial direction. The upper and the lower molds have a base part with a molding surface for a tire-bead and a tire-sidewall, and a tread ring part with a molding surface for a tire-tread and a tire-buttress. The tread ring part is divided by radial split surfaces into a plurality of tread segments supported on the base part tiltably around a center line in the tangential direction of a circle centered on the tire axis between the reference position, where the radial split surfaces of the tread ring part contact to each other, and a releasing position, where the radial split surfaces are separated to each other.
