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.

Assembly for tire including impregnated woven or knitted fabric(s) and a sacrificial holder

Bearing structure () has identical bearing elements () in tension outside contact patch (A) with the ground and in compression in the contact patch (A). Bearing elements () are filamentary and are connected to radially inner face () of radially outer structure of revolution () by radially outer fabric () and to radially outer face () of radially inner structure of revolution () by radially inner fabric (), respectively. Furthermore, mean surface density D of bearing elements () per unit area of radially outer structure of revolution (), expressed in 1/m, is at least equal to (S/S)*Z/(A*F), where S is area, in m, of radially inner face () of radially outer structure of revolution (), Sis connecting area, in m, of radially outer fabric () with radially inner face () of radially outer structure of revolution (), Z is nominal radial load, in N, A is area of contact with the ground, in m, and Fis the force at break, in N, of bearing element ().
