Abstract: A pneumatic radial tire and a method for manufacturing the same, a device for forming a band of radial tire, and a method of and device for forming a belt-band-tread rubber assembly. The pneumatic tire including a belt arranged on the radially outer side or a carcass, and a band arranged on the radially outer side of the belt and composed of continuous one to several organic fiber cords wound spirally and approximately parallel to the circumferential direction of the tire. The radial tire manufacturing method including the steps of laminating the predetermined number of belt plies on a belt drum or belt ring for forming a belt, and winding one to several organic fiber cords continuously and spirally in the cicumferential direction of the belt on the outer surface of the formed belt in order to form a band.
