PROBLEM TO BE SOLVED: To provide a pneumatic tire excellent in on-snow performance while maintaining durability of a blade etc., for forming siping.SOLUTION: A tire vulcanization mold K is provided for molding a tire in which a plurality of segments 8, each of which has a tread forming surface 9 for forming an outer surface of a tread part 2 and a pair of split surfaces 10, 10 provided on both ends in a tire circumferential direction of the tread forming surface 9, are continued in the tire circumferential direction. The tread forming surface 9 is provided with a circumferential bone part 12 extending in the tire circumferential direction, a lateral groove bone part 13 intersecting with the circumferential bone part 12, and a blade 14 including a three-dimensional blade 15 extending in a zig-zag manner. The three-dimensional blade 15 includes: a first blade 15A with its thickness of 0.3 mm or less; and a second blade 15B provided at an end part area 9t adjacent to at least one split surface 10 of the segment 8 and having a thickness of 0.4-0.6 mm. |
