Patent ID: 7309110

Claim:
A tire wheel that includes a first seat and a second seat, intended to receive a tire bead, and an assembly, said tire wheel comprising: a disc that includes a hub bearing surface, a transition zone and a radially outer edge; and a rim that includes: at least a first laminated composite structure formed of one circumferential winding of a fabric of long fibers, said fibers being oriented in two distinct directions and impregnated by a resin, a radially outer surface of said first composite structure corresponding to a portion of a radially outer surface of said rim; at least a second laminated composite structure formed of one circumferential winding of a fabric of long fibers, said fibers being oriented in two distinct directions and impregnated by a resin, a radially outer surface of said second composite structure corresponding to a portion of a radially inner surface of said rim; and at least a first circumferential weight-reduction structure, filling a portion of an annular volume of said rim, said first weight-reduction structure being formed of a material of a density substantially lower than a density of said first and second laminated composite structures, so as to provide reduced rim weight, and said first weight-reduction structure being arranged radially between said first and second laminated composite structures, wherein a radially inner profile of said tire wheel, formed by said radially inner surface of said rim, has a diameter that decreases between a region opposite a mounting groove of said radially outer surface of said rim and a region opposite a circumferential groove of said radially outer surface of said rim.
