摘要:
A pneumatic tire is provided with a carcass configured from at least one carcass ply. The carcass ply is formed by arranging, in the tire circumferential direction, rectangular sheet-shaped ply pieces, each having a radial direction length larger than a tire circumferential direction length. In each of the ply pieces, carcass cords are arranged parallel to each other in the longitudinal direction, and adjacent ply pieces at least partially overlap with each other in the tire circumferential direction, and in each of the ply pieces, the distance (Pe) between the carcass cords in at least one side edge portion in the circumferential direction of the ply piece, is larger than the distance (Pc) between the carcass cords in a central portion of the ply piece.
