Abstract: The invention concerns an elastomer composition for a self-supporting insert (1) intended to support a tyre of a wheel of a vehicle, an insert of which at least one layer (3) comprises said composition and a mounted assembly incorporating said insert. The invention applies to a non-pneumatic mounted assembly, in particular for a vehicle with two wheels, in which each of the tyres is permanently supported by said insert, The elastomer composition comprises, principally by mass, a mixture of at least one first thermoplastic elastomer and at least one second thermoplastic elastomer, and said composition is such that said at least one first thermoplastic elastomer is a copolyamide (COPA) and said at least one second thermoplastic elastomer is a thermoplastic styrene (TPS) elastomer.
