An object is to enhance the fuel economy performance of a tire while maintaining the outer appearance of the tire. The tire vulcanization mold 1 of the present invention includes a tread mold 2 having a tread molding surface 6, and side molds 3 having sidewall molding surfaces 7. A corner portion k1 of a butt surface 4 and the tread molding surface 6 of the tread mold 2 is rounded as a first arc 10. A corner portion k2 of a butt surface 5 and the sidewall molding surface 7 of the side mold 3 is rounded as a second arc 11. A radius of curvature R1 of the first arc 10 is 1.2 to 2.0 times a radius of curvature R2 of the second arc 11. The present invention also relates to a method for producing a tire and to a tire 20.
