Abstract
A wheel assembly may include an inner rim and an outer rim surrounding the inner rim. The wheel assembly may also include gas springs coupled between the inner and outer rims, and a tread assembly carried by the outer rim. The tread assembly may include an inner resilient material layer carried by an outer circumferential surface of the outer rim, and an outer metallic layer carried by the inner resilient material layer to rotatably contact a ground surface as the wheel assembly moves along a path of travel.
