A sulfur-curable rubber composition for incorporation into tires comprises, based on 100 parts by weight of elastomer (phr): (A) at least three diene elastomers each being a different rubber material, a first elastomer being characterized by a high molecular weight in a range of from about 300,000 to about 500,000 and a second elastomer being characterized by a molecular weight in the range of from about 250,000 to 350,000; the at least three elastomers each comprising between 25 and 40 phr; and (B) a reinforcement network comprising a balance of carbon black to silica in about a 3:1 to about 4:1 ratio.
