Abstract:
1. A rubber composition comprising (B) 10 to 200 parts by weight of a low molecular weight aromatic vinyl-conjugated diene copolymer having weight average molecular weight of 1.0×10 based on (A) 100 parts by weight of a rubber component containing at least 60% by weight of a styrene-butadiene copolymer having weight average molecular weight of 5.0×10 which satisfies the following relationship when As (% by weight) is the styrene content of said styrene-butadiene copolymer (A) and Bv (% by weight) is the aromatic vinyl content of said low molecular weight aromatic vinyl-conjugated diene copolymer (B).
