发明名称 PNEUMATIC TIRE MANUFACTURING METHOD, AND PNEUMATIC TIRE
摘要 A pneumatic tire manufacturing method is provided in which winding collapse is prevented, there is no possibility of adverse effects on the FV, a current-carrying layer can be formed easily, and down-stitching can be dispensed with or minimized in the manufacture of SOT-structure pneumatic tires having a base-pen structure in the tread. This pneumatic tire manufacturing method involves: a step in which a sidewall, an inner liner, and a ply are bonded on a first molding drum, beads are set, and the tread side part that will form the current-carrying layer is formed on the side wall, forming a first cover; a step in which a breaker and band are bonded on a second molding drum and the tread center part is formed on the band, shaping the tread ring; a step in which the first cover is inserted inside of the tread ring and inflated to bond to the tread ring with pressure; and a step in which the sidewall is bonded to the lateral surface of the first cover, and the tread side part and the tread center part are bonded together.
