Abstract:
1. A pneumatic tire having a component comprising a vulcanizable rubber composition comprising, based on 100 parts by weight of elastomer (phr), (A) from about 5 to about 30 phr of high trans random SBR comprising from about 3 to about 30 percent by weight of styrene and a trans 1,4 butadiene content in the polybutadiene segments of the SBR of greater than 60 percent by weight, wherein said high trans random SBR is produced by a process that comprises copolymerizing styrene and 1,3-butadiene in an organic solvent in the presence of a catalyst system that is comprised of (B) from about 70 to about 95 phr of at least one additional elastomer.
