| description | The present 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 60 to about 90 phr of a solution polymerized styrene-butadiene rubber functionalized with an alkoxysilane group and at least one functional group selected from the group consisting of primary amines and thiols; (B) from about 40 to about 10 phr of polybutadiene having a microstructure comprised of about 96 to about 99 percent cis 1,4-isomeric units, about 0.1 to about 1 percent trans 1,4-isomeric units and from about 1 to about 3 percent vinyl 1,2-isomeric units; a number average molecular weight (Mn) in a range of from about 75,000 to about 150,000 and a heterogeneity index (Mw/Mn) in a range of from about 3/1 to about 5/1; and (C) from about 50 to about 150 phr of silica. |
