The present disclosure relates to a wheel apparatus that includes a rim module coupleable to an axle and a solid tire module that extends from the rim module. The solid tire module includes a plurality of tread teeth that form a peripheral edge. The peripheral edge forms at least a portion of a tire profile. Each tread tooth of the plurality of tread teeth has a spatial specification that includes a circumferential width, a radial height, an edge shape, and a circumferential gap width. The spatial specifications of the plurality of tread teeth are non-uniform. In one embodiment, the solid tire module has a non-circular rotational trace. In another embodiment, at least a circumferential region of the peripheral edge comprises a sequence of tread teeth having sequentially increasing radial height. |
