The tire has a belt layer in which belt-shaped members are arranged in the circumferential direction of the tire, the belt-shaped members including a plurality of belt cords arranged parallel to each other and covered with rubber, and the belt width of the belt-shaped members is 1 to 10 mm. On the equatorial plane of the tire, two strip-shaped members adjacent in the circumferential direction of the tire are brought into contact with each other at the circumferential end of the tire, or two strip-shaped members adjacent in the circumferential direction of the tire overlap only in the rubber portion in the radial direction of the tire in the end of the belt layer. In a belt ply forming step of a method for manufacturing a tire, belt-shaped members are sequentially attached in a tire circumferential direction at a predetermined angle with respect to the tire circumferential direction, thereby forming a belt ply in which the belt-shaped members are arranged in the tire circumferential direction. In the attaching step, two band-shaped members adjacent in the tire circumferential direction abut against each other at the tire circumferential end on the tire equatorial plane, or in the attaching step, two band-shaped members adjacent in the tire circumferential direction overlap only in the rubber portion in the tire radial direction in the end of the belt layer.
该轮胎具有带束层,在带束层中,带状构件在轮胎周向上排列,该带状构件包括彼此平行排列并由橡胶覆盖的多个带束帘线,并且带状构件的带宽度为1至10mm。在轮胎赤道面上,使在轮胎周向上相邻的两个带状构件在轮胎周向端处彼此抵接,或在带束层的端部中,在轮胎周向上相邻的两个带状构件仅在橡胶部分中沿轮胎径向重叠。在用于制造轮胎的方法的带束帘布层形成步骤中,带状构件以相对于轮胎周向的预定角度在轮胎周向上顺次地被附接,从而形成带状构件在轮胎周向上排列的带束帘布层。在附接步骤中,在轮胎赤道面上,在轮胎周向上相邻的两个带状构件在轮胎周向端处彼此抵接,或在附接步骤中,在带束层的端部中,在轮胎周向上相邻的两个带状构件仅在橡胶部分中沿轮胎径向重叠。
