发明名称 PNEUMATIC TIRE
摘要 In order to enable the suppression of the occurrence of poor appearance, a pneumatic tire (1) is provided with a carcass (6) configured from at least one carcass ply (6A). The carcass ply (6A) is formed by arranging, in the tire circumferential direction, rectangular sheet-shaped ply pieces (11) each having a radial direction length (L2) larger than a tire circumferential direction length (L1). In each of the ply pieces (11), carcass cords (12) are arranged parallel to each other in the longitudinal direction, and the ply piece (11) and a ply piece (11) adjacent thereto at least partially overlap with each other in the tire circumferential direction. Further, in each of the ply pieces (11), the distance (Pe) between the carcass cords (12) in at least one side edge portion (11e) in the circumferential direction of the ply piece (11) is larger than the distance (Pc) between the carcass cords (12) in the central portion (11c) of the ply piece (11).
