The assembly comprises a gimped securing element (18) comprising a core (18a) around which a gimp yarn (18b) is wound. The core (18a) exhibits an elongation at rupture Arupture_core and the gimp yarn (18b) exhibits an elongation at rupture Arupture_gimp such that: Arupture_core<A1=h/(E+e1+e2) and Arupture_gimp>A1=h/(E+e1+e2) in which h is the conformation height of the assembly, e1 is the thickness of the first structure (10), e2 is the thickness of the second structure (12), and E is the lock length.

Abstract: A tire assembly includes an assemblage formed of first and second impregnated woven or knitted structures, a bearing structure, and at least one sacrificial holder. The first impregnated woven or knitted structure includes a first woven or knitted fabric and a first layer of a first polymeric composition. The second impregnated woven or knitted structure includes a second woven or knitted fabric and a second layer of a second polymeric composition. The bearing structure includes bearing elements connecting the first and second woven or knitted fabrics together. Each sacrificial holder is structured to hold temporarily the first and second impregnated structures in contact with each other, connecting the first and second woven or knitted fabrics together. When the first and second impregnated woven or knitted structures are separated from each other, each sacrificial holder breaks before any breakage of the bearing elements.
