Beschreibung
Zusammenfassung:	To provide a rubber composition capable of improving an abrasion resistance, grip sustainability, wet grip properties and dry grip properties of a tire.SOLUTION: The rubber composition includes: a rubber constituent whose glass-transition temperature is -35°C to -5°C, inclusive; an additive for rubber including a sulfur-containing hydrocarbon polymer; and a filler. The sulfur-containing hydrocarbon polymer is a reaction product of unsaturated hydrocarbon and sulfur. The unsaturated hydrocarbon includes an alicyclic unsaturated compound. A weight-average molecular weight of the sulfur-containing hydrocarbon polymer is 500 to 4000, inclusive. A content of the filler is 200 to 500 pts.mass, inclusive, based on the rubber constituent 100 pts.mass.SELECTED DRAWING: None 【課題】タイヤの耐摩耗性、グリップ持続性、ウェットグリップ性、およびドライグリップ性を向上できるゴム組成物の提供。【解決手段】本発明のゴム組成物は、ガラス転移温度が－３５℃以上－５℃以下であるゴム成分と、含硫黄炭化水素重合体を含むゴム用添加剤と、充填剤とを含み、前記含硫黄炭化水素重合体が、不飽和炭化水素と硫黄との反応生成物であり、前記不飽和炭化水素が脂環式不飽和化合物を含み、前記含硫黄不飽和炭化水素重合体の重量平均分子量が５００以上４０００以下であり、前記充填剤の含有量が、前記ゴム成分１００質量部に対して２００質量部以上５００質量部以下であることを特徴とする。【選択図】なし
