There is provided a curable rubber composition comprising a high molecular weight diene elastomer; optionally, a carbon black component; a silica component; and a silane-terminated copolymer different from the high molecular weight diene elastomer, the silane-terminated copolymer comprising a conjugated diene and a vinyl aromatic compound as polymeric monomers. The silane-terminated copolymer has at least one end modified with at least one silane group, and the silane-terminated copolymer has a number average molecular weight of from 1,000 g/mol to 40,000 g/mol. A method for producing a rubber composition for tires is provided. The method includes forming a composition by mixing a silane-terminated copolymer modified with at least one silane group, a silica component, a high molecular weight diene elastomer different from the silane-terminated copolymer, and optionally a carbon black component; and allowing the composition to cure.
