PROBLEM TO BE SOLVED: To provide a method for producing a tire which can continuously mold tires different in size by moving the tires being molded between operating stations without largely changing the structure of the tires and without wasting energy and time. SOLUTION: In the molding of a green tire, a toroidal molding drum which can be expanded/contracted toroidally is moved in a prescribed cycle time between the operating stations. In any operating station, a carcass band and both bead-cores are arranged on the drum, the bead-cores are locked, the drum is expanded to extend the carcass band toroidally between the bead-cores, the side part of the carcass band is turned over around the bead-cores outward and radially, and while the bead-cores are locked to the drum, a tire constitution member is assembled to mold the green tire. After that, the drum is contracted, beads are unlocked, and the green tire is detached from the drum. COPYRIGHT: (C)2004,JPO
