A pneumatic tire (1) is provided with a carcass (6) which comprises, a carcass ply (11) extending from a tread (2) through side walls (3) to the bead cores (5) of bead sections (4), the bead cores (5) each including an inner core (14) and an outer core (15). The carcass, ply (11) is sandwiched between the inner cores (14) and the outer cores (15). Each of an inner core (14) and an outer core (15) includes a bead cord (16) which is wound at least one turn in the circumferential direction of the tire. Each of the bead cords (16) includes an outermost layer (18) formed by twisting filaments (17) together. In at least one bead section, the outermost layer (18) of the bead cord (16) of each of the inner core (14) and the outer core (15) is twisted in the direction which allows the carcass ply (11) to easily move to the outside in the radial direction of the tire from between the inner core (14) and the outer core (15).

Abstract: A method of manufacturing a carcass structure for vehicle tires includes the steps of making at least one carcass ply by deposition of elongated sections circumferentially distributed on a toroidal support and applying annular reinforcing structures to a region close to inner circumferential edges of the at least one carcass ply. Each of the elongated sections extends in a U-shaped configuration around a cross-sectional outline of the toroidal support to define two side portions mutually spaced apart in an axial direction and one crown portion extending at a radially outer position between the side portions. Each of the elongated sections is laid down substantially in a plane parallelly offset relative to a meridian plane of the toroidal support. A related carcass structure and tire are also disclosed.
