A method of manufacturing a pneumatic tire and a manufacturing device for a pneumatic tire capable for suppressing heat degradation in a base tire and forming a tread portion with high dimensional precision. A rigid inner mold (2) made of metal is brought into contact with a tire inner surface across an area corresponding to a tread portion (TR) of the base tire (BT), the strong rigid inner mold (2) supporting the base tire (BT) from the inner side. In this state, unvulcanized rubber (R) is injected into a cavity (11) of a tread mold (10) that covers an outer circumferential surface of the base tire (BT) corresponding to the tread portion (TR). Via vulcanization of this unvulcanized rubber R, a tread portion (TR) is formed on the outer circumferential surface of the base tire (BT) and the tread portion (TR) is integrated with the outer circumferential surface.
