Abstract
A rubber composition for tire having low rolling resistance and high wet skid resistance, breakage strength and wear resistance consists mainly of a rubber component containing at least 20 parts by weight of a high vinyl butadiene-styrene copolymer rubber obtained by copolymerizing randomly styrene with 1,3-butadiene, and containing 3-30% by weight of bonded styrene and 60-95% by weight of 1,2-bond in butadiene unit, and further containing metal-butadienyl bonds in its main chain in a weight fraction of at least 20% by weight.
