PROBLEM TO BE SOLVED: To provide a tire vulcanizing mold capable of optionally setting the depth of a wear indicating hole to be formed in a tire tread part. SOLUTION: In the tire vulcanizing mold with a wear-indicating pin 3 for forming the wear-indicating hole in the tire tread part, installed on a tread molding surface 1, the wear-indicating pin 3 is freely detachable from the tread molding surface 1 and freely adjustable in height from the tread molding surface 1. In more concrete terms, a pin inserting hole 2 is formed in the tread molding surface 1 and an attachment/detachment structure for screwing the wear-indicating pin 3 into the pin inserting hole 2, is formed. Further, a cylindrical part 2a with a smooth contact surface is formed at an adjacent region, to the tread molding surface 1, of the pin inserting hole 2 and a columnar part 3a which comes into contact with the cylindrical part 2a of the pin inserting hole 2 is provided in the wear-indicating pin 3.
