Abstract
A pneumatic tire to reduce separation of a carcass ply from inner and outer core pieces (5i, 5o) and improve steering stability. A radially inner end portion of the carcass ply is held between the inner and outer core pieces (5i, 5o) without turning-up around a bead core. The inner and outer core pieces (5i, 5o) are made of helical body of bead cord (10i, 10o) helically winding around a tire axis. In the inner core piece (5i), the final twisting direction of the bead cord (10i) is the same as the winding direction around the tire axis of the bead cord (10i) in side view from axial outward of the tire. In the outer core piece (5o), the final twisting direction of the bead cord (10o) is opposite to the winding direction of the bead cord (10o).
