To provide a tire rubber composition which is sustainable, is biologically renewable, is friendly to an environment, and is made of a non-fossil fuel resource.SOLUTION: A rubber composition contains, based on 100 pts.wt. of an elastomer (phr), a blend of at least two rubber elastomers selected from the group consisting of approximately 40 phr to approximately 50 phr of polybutadiene, approximately 35 phr or less of a styrene-butadiene copolymer, and approximately 45 phr or less of natural rubber, a bio-derived resin material, and a bio-derived filler containing silica and a carbon black filler. The carbon black filler is at least partially derived from a bio-based supply material after addition to the rubber composition. The resin and the silica are derived from a renewable material.SELECTED DRAWING: None

    【課題】持続可能な、生物再生可能な、環境に優しい、非化石燃料資源からのタイヤゴム組成物を提供する。【解決手段】ゴム組成物は、100重量部のエラストマーに基づいて(phr)、約40phr~約50phrのポリブタジエンと、約35phr以下のスチレン-ブタジエンコポリマーと、約45phr以下の天然ゴムとからなる群から選択された、少なくとも2つのゴムエラストマーのブレンド;バイオ由来の樹脂材料;ならびにシリカおよびカーボンブラック充填剤を含む、バイオ由来の充填剤;を含む。カーボンブラック充填剤は、ゴム組成物への添加前にバイオ系供給材料に少なくとも部分的に由来している。樹脂とシリカも再生可能な材料に由来している。【選択図】なし
