The present invention is directed to a pneumatic tire having a tread comprising a vulcanizable rubber composition comprising, based on 100 parts by weight of elastomer (phr),n (A) from about 40 to about 90 phr of a solution polymerized styrene-butadiene rubber having a glass transition temperature (Tg) ranging from −65° C. to −55° C.; (B) from about 60 to about 10 phr of polybutadiene having a cis 1,4 content greater than 95 percent and a Tg ranging from −80 to −110° C.; and (C) from 45 to 65 phr of a hydrocarbon resin having a Tg ranging from −20° C. to 20° C.; (D) less than 10 phr of oil; (E) from 120 to 160 phr of silica;n nwherein the total amount of resin and oil is less than 70 phr, and the weight ratio of silica to resin is greater than 2. |
