The present invention is directed to a pneumatic tire comprising a vulcanizable rubber composition, the vulcanization rubber composition comprising: 1) 100 parts by weight of elastomer consisting of 25 to 35 phr of a styrene-butadiene rubber, 25 to 35 phr of a polybutadiene, and 35 to 45 phr of a natural rubber or synthetic polyisoprene, wherein the styrene-butadiene rubber is a functionalized solution polymerized styrene-butadiene elastomer having a glass transition temperature Tg(A) ranging from −30 to −10° C. and having at least one functional group; the natural rubber or synthetic polyisoprene has a Tg(B) ranging from −60 to −70° C.; and the polybutadiene is a cis 1,4 polybutadiene having a Tg(C) ranging from −110 to −90° C., wherein Tg(A)−Tg(B)≥25° C., and Tg(B)−Tg(C)≥25° C.; 2) 60 to 80 phr of a prehydrophobated silica; 3) 1 to 10 phr of carbon black; 4) 1 to 3 phr of rubber processing oil; and 5) 5 to 25 phr of at least one hydrocarbon resin having a Tg≥20° C., wherein the weight ratio of hydrocarbon resin to rubber processing oil is greater than 8.
