Tire with rubber sidewall containing trans polybutadiene and brominated copolymer

摘要

A pneumatic rubber tire having a sidewall of a rubber composition of elastomers comprised primarily of a combination of a brominated copolymer of isobutylene and para-methylstyrene and high trans 1,4-polybutadiene polymer, of which a minor portion thereof is one or more additional conjugated diene-based elastomers exclusive of any appreciable amount of high cis 1,4-polybutadiene rubber.
