Abstract
An assembly is formed of a tire (1), a mounting rim (2), and an annular bearing support (3) for the tread (10) of the tire, for running at low pressure or at zero pressure. The rim (2) has two seats (23', 23"), the first seat (23') having an outwardly inclined generatrix and being axially outwardly extended by a shoulder or hump (25'), and the second seat (23") having an inwardly inclined generatrix and being axially outwardly extended by a flange (24). The tire (1) has a radial carcass reinforcement (13) with a particular meridional profile and two beads (12', 12") adapted to the mounting rim (2). The tread supporting ring (3) is ovalizable and circumferentially inextensible.
