PROBLEM TO BE SOLVED: To provide a metal cord-rubber composite suitable for a rubber article such as a tire such as a tire for heavy load such as a track and a bus which highly achieves both enhancement in heat-resistant adhesion between a metal cord and a rubber and enhancement in resistance to crack propagation, and to provide a tire.SOLUTION: There are provided a metal cord-rubber composite obtained by coating a metal cord with a rubber composition, where an N atom on a surface of the metal cord is 2 atom% or more and 60 atom% or less and a Cu/Zn ratio is 1 or more and 4 or less, and the rubber composition contains 1-60 pts.mass of silica with respect to 100 pts.mass of a rubber component, 3-15 mass% of a silane coupling agent with respect to an amount of the silica, and 0-1 pts.mass of a cobalt-containing compound; and a tire using the metal cord-rubber composite.SELECTED DRAWING: None

    【課題】金属コードとゴムとの耐熱接着性の向上と耐亀裂進展性の向上とを高度に両立したトラックやバスなどの重荷重用タイヤなどのタイヤ、工業用ベルトなどのゴム物品に好適な金属コード−ゴム複合体及びタイヤの提供。【解決手段】ゴム組成物を金属コードに被覆してなる金属コード−ゴム複合体であって、金属コードの表面のN原子が2原子%以上60原子%以下、かつCu/Zn比が1以上4以下であり、前記ゴム組成物がゴム成分100質量部に対して、シリカを1〜60質量部、シランカップリング剤を前記シリカ量に対し3〜15質量%含有し、コバルト含有化合物を0〜1質量部含む金属コード−ゴム複合体。前記金属コード−ゴム複合体を用いたタイヤ。【選択図】なし
