摘要： A diene rubber composition comprising 25 to 90 parts by weight of at least one high molecular weight diene rubber (A) having an intrinsic viscosity [η] of at least 2.0 and a glass transition point of not lower than - 50°C and 75 to 10 parts by weight of at least one low molecular weight diene rubber (B) having an intrinsic viscosity [η] of 0.01 to 2.0, said composition having an average intrinsic viscosity of at least 1.8.
Since this composition has an excellent wet grip and rolling resistance property and moreover has excellent processability, it is employed as tire tread rubber.-
