Abstract
YA rubber composition for use in tire having improved rolling resistance, wet skid resistance and processability is disclosed, which comprises at least 20% by weight of a conjugated diolefin-vinyl-substituted aromatic hydrocarbon random copolymer. This random copolymer is produced by copolymerization with a particular initiator and coupling with a particular coupling agent, and has a content of vinyl-substituted aromatic hydrocarbon of 3-60% by weight, a content of tin bonded to copolymer of not less than 400 ppm and a Mooney viscosity (ML.sub.1+4.sup.100.degree.C.) of 20-200.
