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 and an outer rim surrounding the inner rim. The wheel assembly may also include gas springs operatively coupled between the inner rim and the outer rim to provide a gas suspension for relative movement between the inner rim and the outer rim. Each of the gas springs may have a controllable gas pressure. The wheel assembly also includes a wheel rotational position sensor, a vehicle operator control input interface, and a controller configured to control the gas pressure in each of the gas springs in a pattern in response to the wheel rotational position sensor and vehicle operator control input interface to assist in one of overcoming a rolling resistance of the wheel and a braking of the wheel.

A wheel assembly for a vehicle may include an inner rim to be coupled to the vehicle, and an outer rim surrounding the inner rim. The wheel assembly may also include gas springs operatively coupled between the inner rim and the outer rim to provide relative movement between the inner rim and the outer rim. Attachment assemblies may each include an attachment bracket coupled to a corresponding one of the inner and outer rims and defining spaced apart first and second fastener-receiving tapered wedge passageways, and a fastener extending through the spaced apart first and second fastener-receiving tapered wedge passageways and coupling a corresponding gas spring to the attachment bracket. Each attachment assembly may also include first and second tapered wedges carried by the fastener and engaging the respective first and second fastener-receiving tapered wedge passageways upon securing of the fastener.

A wheel assembly for a vehicle may include an inner rim to be coupled to the vehicle, and an outer rim surrounding the inner rim. The wheel assembly may further include gas springs operatively coupled between the inner rim and the outer rim to provide relative movement between the inner rim and the outer rim. A ballistic armor cover plate may extend between the outer and inner rim on an outboard side of the wheel assembly to protectively cover the gas springs.

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.
