RUBBER COMPOSITION FOR TIRE

An object of the present invention is to provide a rubber composition for a tread assuring less temperature dependency of on-ice performance and good wet grip performance and a studless tire composed of the rubber composition. A rubber composition for a tread comprises a rubber component comprising an isoprene rubber, a terpene resin and a branched conjugated diene copolymer, wherein the branched conjugated diene copolymer is prepared by copolymerizing a branched conjugated diene compound represented by the general formula (1):wherein Ris an aliphatic hydrocarbon having 6 to 11 carbon atoms and a conjugated diene compound represented by the general formula (2):wherein Rand Rare the same or different and each is a hydrogen atom, an aliphatic hydrocarbon group having 1 to 3 carbon atoms or a halogen atom, andwherein a copolymerization ratio of the branched conjugated diene compound (1) is 1 to 99% by weight and a copolymerization ratio of the conjugated diene compound (2) is 1 to 99% by weight.
