A pneumatic tire having a circumferential rubber tread comprising a rubber composition is disclosed. The rubber composition comprises, based on parts by weight per 100 parts by weight of the rubber (phr), (A) 100 phr of diene-based elastomers, and (B) 40 to 80 phr of a reinforcing filler comprising a combination of carbon black and silica comprising: (1) 20 to 40 phr of carbon black, and (2) 20 to 40 phr of silica, wherein the silica is used in combination with a silica coupling agent having a moiety reactive with hydroxyl groups on the silica and another different moiety interactive with carbon-to-carbon double bonds of the diene-based elastomers, wherein the diene-based elastomers comprise: (a) from 30 to 50 phr of cis 1,4- polyisoprene rubber, (b) 25 to 45 phr of cis 1,4-polybutadiene rubber, and (c) 15 to 35 phr of styrene/butadiene rubber having a Tg in a range of from -60°C to -85°C, and a styrene content of from 14 to 20 percent.
