Inflatable article equipped with an elastomer layer impermeable to the inflation gases, said elastomer layer comprising at least, as the predominant elastomer, a thermoplastic stirene/isobutylene/stirene (SIBS) elastomer. Preferably the SIBS elastomer comprises between 5% and 50% by weight of stirene, its number-average molecular weight is between 30 000 and 500 000 g/mol, and its Tg is below −20° C. Preferably the airtight elastomer layer also comprises, as a plasticizing agent, an extender oil for the SIBS elastomer with a content preferably between 5 and 100 phr. The inflatable article is, in particular, an inner tube or a pneumatic tire for a motor vehicle.
