摘要：
Provided is a rubber composition which can give a tire excellent in braking performance and fuel consumption and which is excellent in mechanical strength and fatigue resistance, and a use thereof.The rubber composition of the present invention contains a (A) 60 to 0.1 parts by weight of a nonconjugated polyene copolymer, which is a random copolymer containing 96 to 70 mol % of the structural units derived from α-olefin (A1) and 4 to 30 mol % of the structural units derived from a nonconjugated polyene (A2), and has a glass transition temperature (Tg) of −25 to 20° C., (B) 40 to 99.9 parts by weight of a diene rubber and (C) at least one selected from the group consisting of specific polymers.
