摘要：
A rubber composition comprising, as rubber components, 10-40 % by weight of (1) a styrene-butadiene copolymer rubber obtained by solution polymerization, having a styrene content of less than 20% by weight and a trans-1,4 bond content in butadiene portion, of more than 90% by weight and 60-90% by weight of (2) a diene rubber other than the styrene-butadiene copolymer rubber (1), having a glass transition temperature of -60.degree. C. or below.
