The invention is directed to a pneumatic tire having a component
comprising a vulcanizable rubber composition comprising, based on 100
parts by weight of elastomer (phr), (A) from about 35 to about 65 phr
of a solution polymerized styrene-butadiene rubber with a styrene content
of from about 38 to about 50 percent by weight and a Tg of from about
-22.degree. C. to about -10.degree. C.; (B) from about 10 to about 35 phr
of an emulsion or solution polymerized styrene-butadiene rubber with a
styrene content of from about 20 to about 40 percent by weight and a Tg
of from about -55.degree. C. to about -28.degree. C.; (C) from about 10
to about 35 phr of polybutadiene; and (D) from about 10 to about 100 phr
of silica.
