PROBLEM TO BE SOLVED: To provide a pneumatic tire manufacturing method and a vulcanizer that can dispense with a mold release agent applied to the outer surface of a vulcanization bladder or the inner surface of a green tire, and can extend a durable period of a green tire. ! SOLUTION: In a state where a heat resistant bladder cover 10 formed into a cylindrical shape by a low friction material is brought into contact with and fitted to the inner surface of a green tire G before expanding a vulcanization bladder 8, the green tire G is charged into a vulcanization mold 2a, 2b, 2c and the vulcanization mold 2a, 2b, 2c is closed, and then the green tire G is vulcanized for a predetermined time by being heated at a predetermined temperature while pressing the inner surface of the green tire G through the bladder cover 10 at a predetermined pressure by expanding the vulcanization bladder 8. Subsequently, the vulcanized pneumatic tire T is taken out from the opened vulcanization mold 2a, 2b, 2c, and then the blad |
