Self-sealing elastomer composition that can in particular be used as puncture-resistant layer in an inflatable article, comprising at least 30 phr of a saturated thermoplastic stirene elastomer, at most 70 phr of an unsaturated thermoplastic stirene elastomer and more than 200 phr of an oil extender. Inflatable article, such as a tire, provided with a puncture-resistant layer comprising, as self-sealing composition, an elastomer composition according to the invention. Advantageously, the puncture-resistant layer is combined with an airtight layer, for example based on butyl rubber, so as to constitute, in the inflatable article, a puncture-resistant airtight laminate.
