본 발명은, 구름 저항이 작고, 우수한 반발 탄성을 갖는 고무 탄성체를 얻을 수 있는 고무 조성물 및 그의 제조 방법을 제공하는 것 및, 구름 저항이 작고, 우수한 반발 탄성을 갖는 타이어를 제공하는 것을 목적으로 하는 것이다. 본 발명의 고무 조성물은, 공액 디엔계 중합체(A) 30∼95질량% 및 가교 고무 입자(B) 5∼70질량%를 함유하는 고무 성분과, 고무 성분 100질량부에 대하여 20∼100질량부의 실리카(C)를 혼련함으로써 얻어진다.
Objects of the present invention are to provide a rubber composition that can obtain a rubber elastic body having small rolling resistance and excellent impact resilience and a method for producing the same, and to provide a tire having small rolling resistance and excellent impact resilience. The rubber composition of the present invention is obtained by kneading a rubber component containing 30 to 95% by mass of a conjugated diene polymer (A) and 5 to 70% by mass of cross-linked rubber particles (B) with 20 to 100 parts by mass of silica (C) based on 100 parts by mass of the rubber component.
