Abstract:
1. A tire mold comprising a tread mold section including a plurality of segments divided in a tire circumferential direction to mold a tread, the plurality of segments being provided movably in a tire radial direction, and a plurality of transverse ridges provided on each of the segments, the plurality of ridges being spaced from each other in a tire circumferential direction to mold transverse grooves on a tread surface, wherein the ridges positioned at least at circumferential ends of each of the segments are protrusively provided in a posture inclined outward toward tip ends of each segment and away from a radial direction of each segment so as to be directed away from a circumferentially central portion of each segment, and wherein the ridges positioned at least at the circumferential end of each of the segments are set so that the sum of angles of inclination of both side walls of each such ridge is smaller than the sum of angles of inclination of both side walls of a ridge positioned on a circumferentially central portion of the segment.
