Abstract
Mounting rim designed to form a rolling assembly with a tire and an inflatable and inflated tread bearing support, and comprising on each side of the equatorial plane a rim seat inclined outwards and extended axially outwards by a projection or hump, characterized in that it comprises, axially towards the inside between each rim seat for the tire beads and the equatorial plane XX′, at least one truncated conical seat inclined inwards and designed to receive a bead of a tire tread bearing support. The rolling assembly is used either with a bearing support in the form of a toric membrane inflated hard which retains its shape and pressure if the tire is punctured, or with a bearing support in the form of a membrane that can expand in the event of a tire puncture and entirely fill the internal cavity of the tire.
