Abstract
An innerliner for tubeless tires is comprised of at least one non-elastomeric barrier layer such as poly(vinylidene chloride) or ethylene--vinyl alcohol copolymer film with each barrier layer sandwiched between two layers of an elastomeric material adhering to the rubber stock employed in the carcass of the tire. The innerliner has the advantage of imparting equal or better air retention properties to the tire with a substantial reduction in the thickness and weight relative to conventional halobutyl rubber innerliners.
