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.

Abstract: A spoked wheel rim for a wheeled vehicle, a mounted assembly incorporating this rim for such a vehicle and a method for assembling this mounted assembly is provided. This rim has two rim edges and a rim bottom covered by an annular ribbon that is flexible and sealed against the inflation gas that is intended to receive a tire and that is fitted with an inflation valve for inflating this tire. The ribbon includes a central portion conforming to the shape of this rim bottom and two lateral portions protruding axially from these rim edges. The lateral portions are capable of having a portion of their axial width cut off by the detachment of two respective peripheral sections of these lateral portions, so that this ribbon extends from one of the said edges to the other following this detachment.

Abstract: The present invention relates to a spoked wheel rim for a wheeled vehicle, a mounted assembly incorporating this rim for such a vehicle and a method for assembling this mounted assembly. The invention applies in particular to the mounted assemblies for bicycles. This rim (1) has two rim edges (5 and 6) and a rim bottom (2) covered by an annular ribbon (10) that is flexible and sealed against the inflation gas that is intended to receive a tire and that is fitted with an inflation valve for inflating this tire, this ribbon having a central portion (12) conforming to the shape of this rim bottom and two lateral portions (15 and 16) protruding axially from these rim edges. According to the invention, these lateral portions are capable of having a portion of their axial width cut off by the detachment of two respective peripheral sections (15a and 16a) of these lateral portions, so that this ribbon extends from one of the said edges to the other following this detachment.
