Abstract: A method of forming a layer of tire ply is disclosed. A first strip of ply is provided having a plurality of evenly spaced reinforcement cords, having a spacing S, and having a lateral end, wherein the last cord is spaced apart from strip end a distance X, wherein X is not equal to S. A second strip of ply is provided having a plurality of evenly spaced reinforcement cords, having a spacing S, and having a lateral end, wherein the last cord is spaced apart from strip end a distance Y, wherein Y is not equal to S. The lateral ends of the first and second strip are joined together in a lap joint. The first and second lateral ends are overlapped so that the spacing X preferrably does not overlap, but may partially overlap with the spacing Y.

Abstract: A pneumatic tire has a tire skeleton portion in which a plurality of arranged reinforcing cords are covered by a rubber layer. The reinforcement cords are organic fiber cords formed from polyethylene terephthalate. The organic fiber cords have an intermediate elongation (2.0 cN/dtex) of 3.0% to 4.0%, a dimensional stability index of 5.0% to 6.5%, and a difference between an elongation ratio at a strength at 70% the strength at the time of breaking and an elongation ratio at the time of breaking in a strength-elongation curve of 11% to 16%.

Abstract: A pneumatic tire has carcass layers mounted between a pair of bead parts, the carcass layers being wound from the inner side of the tire to the outer side thereof about a bead core of each bead part. Protective layers including organic fiber cords are positioned in sidewall parts on the outer side of the carcass layers. The upper end parts of the protective layers are positioned along the carcass layers from outer end locations of the belt layers, between a location 20 mm toward the inner side in the tire width direction and a location 15 mm toward the outer side in the tire width direction. The lower end parts of the protective layers are positioned between main body portions of the carcass layers and the bead filler.

Abstract: 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).
