A load-bearing structure for a bearing support intended to be mounted on a rim inside a tire fitted on a vehicle to support the tread of the tire in the event of a loss of inflation pressure is provided. The load-bearing structure includes a base, a crown, and an annular body connecting the base and the crown. The body includes a plurality of partitions distributed regularly circumferentially, extending axially substantially from one side to the other of the body and radially from the base to the crown with a mean orientation relative to the radial direction of between 10 and 50 degrees, in that two circumferentially adjacent partitions exhibit contrary orientations relative to the radial direction and in that two adjacent partitions define with the base and/or the crown cavities in the form of triangles or trapezoids.
