Wheel rim with reduced-height rim flange

A rim for a rolling assembly having two flexible extenders that are identical, a tire being mounted on the flexible extenders, the flexible extenders being mounted on the rim, the rim having an axis of rotation DD′, the rim having a rim seat extended axially toward the outside by a rim flange, the rim flange comprising a radially outer bearing face having a first portion that is oriented substantially in a plane perpendicular to the axis of rotation DD′ and situated radially on the outside with respect to the rim seat,

• wherein a radial height measured between the intersection point between a line of the rim seat and a line of the first portion and the end of the radially outermost portion of the rim flange is less than 10 mm,
• wherein each of the flexible extenders comprises an axially inner end that is intended to couple each of the flexible extenders to the rim, an axially outer end that is intended to receive a tire bead, and a flexible body that connects the axially inner end and the axially outer end,
• wherein the axially inner end has an axial positioning face substantially in the plane perpendicular to the axis of rotation DD′,
• wherein the flexible body has a radially inner face being in contact with the radially outer bearing face of the rim flange across its entire axial width of the bearing face, and
• wherein the radially outer bearing face of the rim flange further comprises:
• a second portion that is inclined toward the outside, situated axially on the outside with respect to the first portion, and situated at least partially radially on the outside with respect to the rim seat;
• and
• a connecting portion that is situated axially between the first portion and the second portion wherein the received tire bead is positioned such that it radially overlaps at least a portion of the rim flange.
