Method for manufacturing a tire

A method for manufacturing a tire comprising the steps of:

• molding a green tire on a bladder in molding step;
• connecting and fixing the upper bead and lower bead of the green tire while keeping them in the airtight state and sealing a pressure gas into the bladder located in the internal space of the green tire to lay it in the expanded state until the molded green tire has been carried into the mold of a vulcanizer;
• and
• heating the green tire using an induction heating coil mounted in the internal space of the green tire.

A method for manufacturing a tire comprising the steps of:

• arranging a retaining mechanism in a tire molding machine in a molding step;
• molding a green tire around the retaining mechanism;
• connecting and fixing the upper bead and lower bead of the green tire while keeping them in the airtight state;
• sealing a pressure gas to the internal space of the green tire to expand it prior to the taking-out of the green tire from the molding step;
• heating the green tire using an induction heating coil mounted on the retaining mechanism and in an internal space of the green tire;
• carrying the green tire to a vulcanization step in this state;
• and
• vulcanization-molding the green tire within the mold of a vulcanizer in the vulcanization step.
