In a method for producing a pneumatic tire, a vulcanizing step of heating and vulcanizing, inside a mold, an unvulcanized green tire having a pair of bead regions, side wall regions extended, respectively, from the bead regions toward the outside of the tire in the radius direction of the tire, and a tread region extended and joined to an outside end of each of the side wall regions to form a tread satisfies the following: To/So=1.00 to 1.10 (1), and To/Ti=0.70 to 0.90 (2). wherein To (° C.) represents the temperature of the outside surface of the tread region in the vulcanizing step, So (° C.) represents the temperature of the outside surface of the side wall regions in the step, and Ti (° C.) represents the temperature of the inside surface of the tread region in the step. |
