RUBBER COMPOSITION, METHOD FOR PRODUCING SAME, AND TIRE

A rubber composition which can obtain a rubber elastic body having small rolling resistance and excellent impact resilience and a method for producing the same, and a tire having small rolling resistance and excellent impact resilience are provided. The rubber composition of the present invention is obtained by kneading a rubber component comprising a conjugated diene polymer having at least one functional group selected from the group consisting of a tertiary amino group, a thiol group, an epoxy group, a thioepoxy group, an oxetane group and a hydrocarbylthio group, a catalyst for condensing silanol, and silica.
