Pneumatic tire having a component containing a rubber triblend and silica

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 35 to 65 phr of a solution polymerized styrene-butadiene rubber with a styrene content of from 38 to 50 percent by weight and a Tg of from -22°C to -10°C;(B) from 10 to 35 phr of an emulsion or solution polymerized styrene-butadiene rubber with a styrene content of from 20 to 40 percent by weight and a Tg of from -55°C to -28°C;(C) from 10 to 35 phr of polybutadiene; and(D) from 10 to 100 phr of silica.
