Abstract:
PROBLEM TO BE SOLVED: To provide a method for vulcanizing a pneumatic tire capable of producing a tire improved in quality by reducing a vertical temperature difference in a vulcanization bladder while rapidly increasing internal pressure of a vulcanization bladder.SOLUTION: A green tire G is vulcanized in a tire mold 10 in a state where a vulcanization bladder 2 is expanded at a predetermined internal pressure P by injecting a heating medium M1 into the vulcanization bladder 2 into which a green tire G is inserted and injecting a pressure medium M2 having a specific gravity larger than that of the heating medium M1 immediately after setting the vulcanization bladder 2 at a preset initial internal pressure P1 after completion of the injection.SELECTED DRAWING: Figure 2
