PROBLEM TO BE SOLVED: To enhance production efficiency by inhibiting the cutting of a vent spew during releasing a tire from a mold and also improve an appearance quality by inhibiting the cut remnant of the vent spew in trimming. SOLUTION: This tire molding mold has a vent hole 1 extending from the tire molding surface 4 side to the outside of the mold and also, a fine groove 2 carved extending from the tire molding surface 4 side to the outside of the mold in the inner surface of the vent hole 1. Alternatively, the tire molding mold has the vent hole 1 extending from the tire molding surface 4 side to the outside of the mold, with a spot facing 3 formed on the tire molding surface 4 side and also, has the fine groove 2 carved extending from the tire molding surface 4 side to the outside of the mold in the inner surface of the vent hole 1.
