A tire mold with an improved bead ring is provided to improve structure of the bead ring of the tire mold to remarkably increase productivity of a tire manufacturing process. A tire mold with an improved bead ring comprises upper and lower molds, a tread mold, and a bead ring(2). The tread mold is coupled with the upper and lower molds to form a tread of a tire. The bead ring is coupled with upper and lower inner peripheries of the upper and lower molds to form a bead part(11) of the tire. The bead ring includes a first contact surface, a second contact surface, and a first curved part. The first contact surface is in contact with a lower end of the bead part. The second contact surface is in contact with a bladder(20) to contact an outer surface of the tire with the tire mold. The first curved part has a predetermined radius and is formed between the first contact surface and the second contact surface.
