Zusammenfassung:	To provide good adhesiveness with a steel cord to a rubber coating the steel cord, under a condition that a metal member such as the steel cord is used as a reinforcement material because of strong impact or large load to a belt layer arranged between a tire under tread and a carcass layer.SOLUTION: The above described problem is solved by a rubber composition in which blended amount of carbon black is 40 to 80 pts.mass based on 100 pts.mass of a diene rubber containing a natural rubber and/or a synthetic isoprene rubber, a relationship of blended amount of a phosphite ester compound and sulfur is 0.5/50 to 50/50 as former/later (mass ratio), and blended amount of zinc oxide is 5 pts.mass or more and less than 12 pts.mass based on 100 pts.mass of the diene rubber.SELECTED DRAWING: None 【課題】タイヤアンダートレッドとカーカス層との間に配設されたベルト層には、強い衝撃や大きな荷重がかかるため、補強材としてスチールコードのような金属部材が用いられている。このようなスチールコードを被覆するゴムは、スチールコードとの良好な接着性が必要とされる。【解決手段】天然ゴムおよび／または合成イソプレンゴムを含むジエン系ゴム１００質量部に対し、カーボンブラックの配合量が４０〜８０質量部であり、亜リン酸エステル化合物および硫黄の配合量の関係が、前者／後者（質量比）として、０．５／５０〜５０／５０であり、かつ前記ジエン系ゴム１００質量部に対し、酸化亜鉛の配合量が５質量部以上１２質量部未満であるゴム組成物によって、上記課題を解決した。【選択図】なし
