摘要： A process is provided for the manufacture of radial tires for vehicle wheels, having an annular reinforcement structure inserted between the tread and the casing. The reinforcement structure has two layers of metal cord and in a radially outer position a third layer of cords arranged in a longitudinal direction. The third layer is made of a textile material which shrinks when heated. The process comprises the steps of first shaping the vulcanized casing to form a toroid, then applying to the shaped casing the two layers of metal cords together with a portion of the layer of textile cords at each side zone of the reinforcement structure. The width of the side zone is between 1/3 and 1/10 of the total width of the structure. The casing is shaped a second time to increase the external equatorial development thereof to a value greater than that reached during the first shaping step. The remaining central portion of the layer of textile cord is then applied on top of the layers of metal cords. A band of elastomeric material, forming the tread of the carcass is disposed on top of the layer of textile cords. The structure is then expanded and vulcanized in a pressurized mold.
