To provide a tire which reduces exposure of a bead core and a recess using a bead member obtained by integrally molding a bead core where bead cords are covered with a resin and a resin-made bead filler.SOLUTION: In a tire 10 and a method for manufacturing the tire, a bead core 61 where a space between bead cords 61a is covered with a resin material 61b and a resin material-made bead filler 63 covering the bead core 61 are integrally molded, and in the tire 10, a bead member 65 around which a carcass ply 40 is folded is included in a bead part 60. On a cross section in a tire width direction WD and a tire radial direction RD of the bead member 65, a central position of the bead core 61 is arranged so as to be deviated from a width direction center BCL of the bead member 65.SELECTED DRAWING: Figure 2
【課題】ビードコードが樹脂によって被覆されたビードコアと樹脂製のビードフィラーとが一体成形されたビード部材を用いつつ、ビードコアの露出及び凹部を低減したタイヤを提供する。【解決手段】タイヤ10およびタイヤの製造方法では、ビードコード61a間を樹脂材料61bで被覆されたビードコア61とビードコア61を覆う樹脂材料製のビードフィラー63とが一体成形され、タイヤ10内において、その周りでカーカスプライ40が折り返されるビード部材65が、ビード部60に含まれる。ビード部材65の、タイヤ幅方向WD及びタイヤ径方向RDに沿った断面では、ビードコア61の中心位置がビード部材65の幅方向中心BCLからずれて配置される。【選択図】図2
