Abstract
A wheel includes a first hoop attached to a second hoop about a circumferential interface. The first and second hoops form at least part of an enclosed box structure positioned circumferentially around the wheel and adjacent to an outboard side of the wheel. The box structure may be formed at least in part by circumferential projections of the first hoop and the second hoop. The wheel may also include a central hub that optionally includes spokes. In some embodiments, the central hub may form part of the enclosed box structure. In some embodiments, a first hoop portion and a second hoop portion may be integral or unitary, with a box structure integrally formed between the hoop portions.
