Patent ID: 6883569

Claim:
Rolling assembly comprising a tire with two beads, a substantially cylindrical rim, a collar comprising a polymeric central portion with two axial edges each reinforced by at least one ring, and between the edges, the central portion including an armature of reinforcement elements such that the central portion is sufficiently flexible to allow the radial displacement of a first blocking element of the central portion into and out of engagement with a second blocking element of the rim to axially lock the tire to the rim, one of the first and second blocking elements comprising a groove into which the other of the first and second blocking elements is received, wherein the reinforcement of each edge of the collar comprises a collar hook with a seat and a flange, an axial contact width defined by contact between the tire and the rim being smaller than an axial distance separating axially inside ends of the seats of the collar, the central portion of the collar extending continuously from one collar hook to the other, wherein the tire and the collar are arranged to be inserted as a unit over the rim in one axial direction when the tire is at reduced pressure.
