Abstract: 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.
