A pneumatic tire having an inner liner of a cured rubber compound containing trans 1,4-polybutadiene rubber

摘要

The present invention relates to an air rubber tire having an integral inner liner of a sulfur-cured rubber compound. Wherein the rubber compound comprises, based on 100 parts by weight of the rubber, (A) 70 to 98 parts by weight of a rubber selected from the group consisting of butyl rubber, chlorobutyl rubber, bromobutyl rubber and mixtures thereof; (B) 2 to 30 parts by weight of a trans 1,4-polybutadiene rubber having 65% or more of trans 1,4-components; And (C) 0 to 30 parts by weight of a rubber selected from the group consisting of acrylonitrile / butadiene copolymer, styrene / butadiene copolymer, natural rubber and mixtures thereof.
