Abstract

PURPOSE: A rubber composition having improved processing characteristics, low vulcanization return, and improved balance of wear resistance and wet skid resistance, comprising two or more specific styrene-butadiene copolymers.
CONSTITUTION: (A) A styrene-butadiene copolymer having a styrene content of 5W60wt% and a vinyl bond amount of the butadiene part of 35W85wt% is blended with (B) a styrene-butadiene copolymer having a styrene content of 5W40wt% and a vinyl bond amount of butadiene part of 1W25wt% and (C) one or more rubber-like polymers of natural rubber, polyisoprene, and polybutadiene having a vinyl bond amount of 1W20wt% as raw material rubber in such a way that a weight ratio of the component A to component B is (20W80):(80W20), preferably (25W75):(75W25) and a weight ratio of component A+B to component C is (100W25):(0W75).
