Manufacturing method and manufacturing device of pneumatic tire

The invention provides a manufacturing method and a manufacturing device of a pneumatic tire. The manufacturing method and the manufacturing device suppress the deviation of temperature difference ofa green tire during vulcanization. A process for heating and pressurizing a green tire (R) in a method for manufacturing the pneumatic tire according to the present invention comprises the steps of (i) supplying a vulcanization gas to the inside of an airbag (6) positioned inside the green tire (R),so that the internal pressure becomes a first pressure; (ii) releasing the gas inside the airbag (6); (iii) stopping the release of the gas when the internal pressure of the airbag (6) drops to a second pressure; and (iv) increasing the internal pressure of the airbag (6) by supplying the vulcanization gas into the airbag (6). 提供充气轮胎的制造方法以及制造装置，抑制了硫化时的生胎的温度差的偏差。本发明的充气轮胎的制造方法中的对生胎(R)进行加热和加压的工序包含如下工序：(i)以使内压成为第一压力的方式向位于生胎(R)的内侧的气囊(6)内部供给硫化用气体；(ii)将上述气囊(6)内部的气体释放；(iii)当上述气囊(6)的内压下降到第二压力时，停止气体的释放；以及(iv)通过向上述气囊(6)内部供给上述硫化用气体
