To solve the problem in which: a compound for tire cap tread with a high silica content requires (1) excellent wear resistance and (2) improved electrical conductivity, but the techniques satisfying all of them has not existed conventionally.SOLUTION: The problem is solved by a tire rubber composition that contains, based on diene rubber 100 pts.mass, 40-150 pts.mass of silica, and 0.1-10 pts.mass of a carbon nanotube-polymer complex in which a polymer is attached to at least a part of carbon nanotubes.SELECTED DRAWING: None
【課題】高シリカ配合のタイヤキャップトレッド用コンパウンドには、(1)耐摩耗性に優れること、(2)電気伝導性を向上させることが求められているが、これらをすべて満足させる従来技術は存在しなかった。【解決手段】ジエン系ゴム100質量部に対し、シリカを40〜150質量部、および、カーボンナノチューブの少なくとも1部にポリマーが添着したカーボンナノチューブ−ポリマー複合体を0.1〜10質量部配合してなることを特徴とするタイヤ用ゴム組成物によって上記課題を解決した。【選択図】なし
