Pneumatic tire

Abstract:

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), (A) from about 45 to about 100 phr of a low-cis polybutadiene having a vinyl-1,2 content ranging from 5 to 30 percent and a Tg ranging from -95.degree. C. to -70.degree. C.; (B) from about 0 to about 40 phr of a solution polymerized styrene-butadiene rubber having a glass transition temperature (Tg) ranging from -85.degree. C. to -50.degree. C.; (C) from 0 to 30 phr of natural rubber or synthetic polyisoprene; (D) from 0 to 20 phr of a process oil; (E) from 55 to 80 phr of a resin having an aromatic hydrogen content ranging from 3 to 30 mole percent, the resin having a Tg greater than 30.degree. C.; and (F) from 110 to 160 phr of silica.
