Abstract:
A pneumatic tire has a carcass composed of at least one carcass ply extending from a tread part through sidewall parts and turned up around a bead core in each of two bead parts. The carcass ply comprises a plurality of ply strips which are continuously arranged in the tire circumferential direction with overlapping portions, wherein one end in the tire circumferential direction of one ply strip overlaps to an outer surface of an adjacent ply strip adjacently arranged on one end side, and the other end in the tire circumferential direction of the one ply strip overlaps to an inner surface of an adjacent ply strip adjacently arranged on other end side.
