Abstract:
A primary formed body is formed by fitting bead rings to outside end portions of a cylindrical body having a film and a carcass material disposed on an outer peripheral side of the film. A green tire is formed on a rigid inner mold by causing a center portion of the primary formed body to bulge toward an outer peripheral side, and holding the center portion by suction on the inner peripheral surface of the transferring/holding mold having a similar shape to the outer peripheral surface of the rigid inner mold, and suspending the suction with the transferring/holding mold, and transferring the primary formed body to an outer peripheral surface of a bladder. The bladder has a uniform thickness and an outer peripheral surface in a neutral state similar to a profile of an inner peripheral surface of a tire to be produced. The green tire is vulcanized.
