A pneumatic object is provided with a layer that is airtight to inflation gases. The layer includes an elastomer composition having at least a thermoplastic elastomer (TPE), as a sole elastomer or as a predominant elastomer by weight, and a hydrocarbon resin. A glass transition temperature of the hydrocarbon resin is above 0° C. The TPE is a copolymer that includes at least a central polyisobutylene block. Optionally, the elastomer composition includes an extender oil. Also optionally, the elastomer composition includes a platy filler selected from a group that includes graphites and phyllosilicates, such as micas, clays, and talcs. The pneumatic object may be an inner tube or a pneumatic tyre for a motor vehicle.
