A rubber composition for use in a tire tread is disclosed. The rubber composition comprises, based on parts by weight per 100 parts by weight elastomer (phr): (A) 100 parts by weight of a combination of conjugated diene-based elastomers comprising: (1) from 10 to 50 phr of an organic solvent polymerization prepared styrene/butadiene elastomer (S-SBR) having a Tg in a range of from -40°C to -30°C and having a styrene content in a range of from 30 to 35 percent, wherein the S-SBR is extended with from 10 to 38 parts by weight per 100 parts of the S-SBR of triglyceride vegetable oil; (2) from 10 to 50 phr of aqueous emulsion polymerization prepared styrene/butadiene elastomer (E-SBR) having a Tg in a range of from -65°C to -45°C and having a styrene content in a range of from 15 to 30 percent, and (3) from 20 to 60 phr of 1,4-polybutadiene rubber having a cis 1,4-isomeric content of at least 92 percent and having a Tg in a range of from - 90°C to -108°C; (B) from 50 to 250 phr of a filler comprising silica; and (C) from 5 to 45 phr of a resin comprising at least one of terpene, coumarone indene and styrene-alphamethylstyrene resins having a softening point within a range of from 60°C to 150°C.
