A pneumatic tire having a circumferential tread of a cap/base configuration with an outer tread cap rubber layer comprising a tire running surface and a tread base rubber layer, the tread base rubber layer at least partially or completely underlying the outer tread cap rubber layer, is disclosed. The rubber composition of the outer tread cap rubber comprises, based on parts by weight per 100 parts by weight of the tread rubber (phr), (A) 55 to 85 phr of cis 1,4-polybutadiene rubber, and (B) 45 to 15 phr of at least one additional diene-based elastomer including cis 1,4-polyisoprene rubber, (C) 40 to 110 phr of a reinforcing filler wherein the reinforcing filler is a combination of a rubber reinforcing carbon black and silica, the reinforcing filler comprising: (1) 20 to 60 phr of rubber reinforcing carbon black, and (2) 10 to 80 phr of silica; and (D) a 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 cis 1,4-polybutadiene rubber.
