Abstract
A method of making a green tire comprises: winding a carcass ply of rubberized cords around a building drum into a substantially cylindrical body; pressing the cylindrical body against the building drum through the entire circumference not to allow the carcass cords to move axially and circumferentially of the drum; constricting edge portions of the substantially cylindrical body so that the outer diameter thereof is decreased; setting a bead core around each of the constricted edge portions; folding back the edge portions around the bead cores; releasing the cylindrical body from the pressing against the building drum after the edge portions are constricted at the earliest; and swelling a main portion of the cylindrical body between the bead cores while decreasing the width between the bead cores.
