Tire rubber composition and containing combination of resin and vegetable oil

A rubber composition and a tire comprising such a rubber composition is disclosed. The rubber composition comprises, based on parts by weight per 100 parts by weight of elastomer (phr): (A) at least one conjugated diene-based elastomer, preferably including at least one conjugated diene-based elastomer that contains one or more functional groups reactive with hydroxyl groups contained on silica; (B) from 5 to 60 phr of at least one triglyceride vegetable oil; (C) from 1 to 30 phr of a resin comprising at least one of a coumarone-indene resin, an alkylated hydrocarbon resin, an aromatic petroleum resin, a dicyclopentadiene resin and a styrene-alphamethylstyrene resin; (D) from 30 to 140 phr of a reinforcing filler comprising: (1) silica, or (2) a combination of carbon black and silica; and (E) a silica coupling agent reactive with hydroxyl groups contained on the silica and another different moiety interactive with carbon-to-carbon double bonds of the conjugated diene-based elastomer; wherein the rubber composition is free of oil extended elastomer.
