RUBBER COMPOSITION, PRODUCTION METHOD THEREFOR AND TIRE

摘要

The purpose of this invention is to provide a rubber composition with which a rubber elastic body having low rolling resistance and excellent impact resilience can be obtained, and a production method therefor. Furthermore, a tire having low rolling resistance and excellent impact resilience is also disclosed. The rubber composition according to the present invention is obtained by kneading a conjugated diene-based polymer (A) having a group with silica binding reactivity at only one site of a single molecule, a polymer (B) having a group with silica binding reactivity at several sites of a single molecule, and a silica-containing filler (C).
