Systems and methods disclosed herein may be useful for use in a wheel assembly. In this regard a wheel assembly may comprise a wheel base with a center axis, a side rim disposed about a circumference of the wheel base, wherein the side rim includes a frustoconical radially inward surface, and a lock ring comprising a single unitary member. The lock ring may secure the side rim onto the wheel base, the lock ring preventing the side rim from sliding axially with respect to the wheel base, wherein a frustoconical radially outward surface of the lock ring comprises a first angle with respect to the frustoconical radially inward surface of the side rim.

A wheel assembly may include an inner rim to be coupled to a hub of a vehicle, an outer rim surrounding the inner rim, and gas springs operatively coupled between the inner and outer rims to provide a gas suspension. The wheel assembly may also include tread assemblies carried by the outer rim. The wheel assembly may also include fastener assemblies. Each fastener assembly may couple respective adjacent wheel assembly components. Each fastener assembly may include a fastener, a lock washer having a sloped surface, and a slotted wedge including a frusto-conical body having a slot therein. The slotted wedge may have a sloped surface slidably engaging the lock washer sloped surface to permit relative rotation so that loosening from a fully tightened position exposes a gap therebetween.

A wheel assembly may include an inner rim to be coupled to a hub of a vehicle, an outer rim surrounding the inner rim, and a rigid cover ring coupled to the outer rim and extending radially inward toward the inner rim. The wheel assembly may also include gas springs operatively coupled between the inner and outer rims to provide a gas suspension for relative movement between the inner and outer rims. The wheel assembly may also include fastener assemblies, each coupling respective adjacent components and including a fastener, a lock washer carried by the fastener and having a sloped surface, and a slotted wedge carried by the fastener and including a frusto-conical body having a slot therein.
