A wheel assembly to be coupled to a hub of a vehicle, may include an inner rim to be coupled to the hub of the vehicle, an outer rim surrounding the hub, and gas springs operatively coupled between the inner rim and the outer rim to provide a gas suspension permitting relative movement between the inner rim and the outer rim. The wheel assembly may also include a sidewall cover assembly that includes an inner sidewall cover coupled to the inner rim and extending radially outward toward the outer rim. The sidewall cover assembly may also include an outer sidewall cover coupled to the outer rim and extending radially inward toward the inner rim and in sliding overlapping relation with the inner sidewall cover permitting relative movement between the inner sidewall cover and the outer sidewall cover.

A wheel device includes: a wheel member; a tire disposed on the outside of the wheel member, the tire comprising an inner layer, an outer layer, and a plurality of hollow pipes disposed between the inner layer and the outer layer, wherein an inner circumferential surface of the inner layer comprises grooves; a plurality of support members each having a circular arc shape; and a plurality of spoke members respectively connecting the wheel member to the plurality of support members. The plurality of spoke members are configured to move the plurality of support members between a first position and a second position. In the first position, each of the support members are disposed in the grooves. In the second position, each of the support members are disposed closer to a central axis of the tire than when the support members are in the first position.
