Provided is a rubber composition which has excellent product stability due to excellent dispersibility of silica, and which is capable of forming a crosslinked rubber product having excellent low fuel consumption characteristics and durability. This rubber composition contains a conjugated diene polymer, silica, a sulfide silane coupling agent, and a cross-linking agent, and the value of tc10, which is a vulcanization characteristic index measured in accordance with JIS K6300-2 using a vibratory vulcanization tester, satisfies formula (1). (1) 0.8 min < tc10 < 5.0 min.
本发明提供一种因二氧化硅的分散性优异而产品稳定性优异、并且能够形成低油耗特性和耐久性优异的橡胶交联物的橡胶组合物。本发明提供的橡胶组合物含有共轭二烯系聚合物、二氧化硅、硫化物系硅烷偶联剂以及交联剂,使用振动式硫化试验机按照JIS K6300‑2测定的硫化特性指标即tc10的值满足下述式(1)。0.8分钟<tc10<5.0分钟(1)。
