The invention concerns a mount rim (J) designed to form a running assembly with a tyre and an inflatable and inflated tread bearing support (3), and comprising on either side of an equatorial plane of the rim seat (10', 10'') sloping outwards and axially extended outwards by a projection or hump (11', 1''). The invention is characterised in that it comprises, axially inwards between each rim seat (10', 10'') for the tyre bead (20', 20'') and the equatorial plane (XX') at least a truncated seat (12', 12'') sloping outwards and designed to receive a bead (30', 30'') providing pneumatic bearing support (3) for the running tread. The running assembly is used either with a bearing support (3) in the form of a highly inflated doughnut-shaped membrane and preserving its shape and pressure in case the tyre is punctured, or with a bearing support (3) in the form of an expansible membrane in case the tyre is punctured completely filling the tyre cavity.
Jante de montage (J), destinée à former un ensemble roulant avec un pneumatique et un appui de soutien (3) de bande de roulement gonflable et gonflé, et comprenant de chaque côté du plan équatorial un siège de jante (10', 10'') incliné vers l'extérieur et prolongé axialement vers l'extérieur par une saillie ou hump (11', 11''), caractérisée en ce qu'elle comprend, axialement vers l'intérieur entre chaque siège de jante (10', 10'') pour bourrelet (20', 20'') de pneumatique et le plan équatorial (XX'), au moins un siège tronconique (12', 12'') incliné vers l'intérieur et destiné à recevoir un bourrelet (30', 30'') d'appui de soutien pneumatique (3) de bande de roulement. L'ensemble roulant est utilisé soit avec un appui de soutien (3) sous forme de membrane torique fortement gonflée et conservant forme et pression en cas de crevaison du pneumatique, soit avec un appui de soutien (3) sous forme de membrane expansible dans le cas de crevaison du pneumatique et remplissant en totalité la cavité interne du pneumatique.
