The modern radial tire was in many respects made possible through the application of halobutyl rubbers such Exxon™ bromobutyl and chlorobutyl halobutyl rubber in the innerliners. Use of these rubbers in the innerliner compound enabled improvements in air retention performance, improvements in liner-to-tire casing adhesion and improvements in tire durability.
