Tubeless tire inner liners of butyl rubber or halobutyl rubber are formed by applying to the inner surfaces of such tire carcasses, either during their manufacture, or to previously made tires, i.e. new tire casings or used tire casings for retreading, a coating of the said rubber, as a sprayable, self-curing, or mild heat curing rubber cement, the rubber or blends of rubbers having a viscosity average molecular weight, in the case of a single rubber, or a calculated averaged viscosity average molecular weight, in the case of a blend of rubbers, of between about 28,000 and about 285,000, with the cement having a total solids content of between about 20 and about 80 wt. %, the remainder being organic solvent. |
