    摘要: 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° C. to about −10° 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° C. to about −28° C.; (C) from about 10 to about 35 phr of polybutadiene; and (D) from about 10 to about 100 phr of silica.
