A wheel assembly includes a plurality of discreet, axially extending curved friction plates for engaging a first side of a spoke structure of a tire assembly, a first annular rim piece for engaging a rotatable axle, and a second annular rim piece for engaging the first rim piece. The first rim piece and the second rim piece each have axially extending lugs for engaging opposite ends of the friction plates.

A wheel assembly 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 and permitting relative movement therebetween. The wheel assembly may also include a rigid inboard cover ring coupled to an inboard side of the outer rim and extending radially inward toward the inner rim. A flexible inboard seal may be coupled between the rigid inboard cover ring and the inner rim.

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 hub. 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. The wheel assembly may also include a disk coupled to the inner rim. The wheel assembly may also include inboard lateral stops carried by an inboard interior surface of the outer rim, and outboard lateral stops carried by an outboard interior surface of the outer rim so that the inboard lateral stops and the outboard lateral stops cooperate to limit relative lateral movement of the disk and the outer rim.

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 hub. The wheel assembly may also include gas springs operatively coupled between the inner rim and the outer rim. At least one gas spring may have a controllable operating response.

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 include gas springs operatively coupled between the inner rim and the outer rim and tread assemblies carried by the outer 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. The wheel assembly may also include a disk coupled to the inner rim and defining a closeable gap with adjacent interior portions of the outer rim to define a mechanical stop to limit relative movement of the inner rim and outer rim.

A wheel assembly may include an inner rim to be coupled to the hub of the vehicle, and an outer rim surrounding the inner rim. Gas springs may be operatively coupled between the inner rim and the outer rim and permitting relative movement therebetween. The wheel assembly may also include a sensor configured to sense the relative movement between the inner and outer rims.

A tire is configured to be received by a wheel having at least one angled surface. The tire includes a tread portion, a first sidewall, and a second sidewall. The first sidewall has a first outer surface, a first inner surface, and a first projection extending inwardly from the first inner surface. The first projection has a first angled surface configured to engage a first corresponding surface of a wheel. The second sidewall has a second outer surface, a second inner surface, and a second projection extending inwardly from the second inner surface. The second projection has a second angled surface configured to engage a second corresponding surface of the wheel.

A non-pneumatic tire includes a circumferential tread having a first axial width. The tire further includes a lower annular band having a circumferential convex curved surface and a second axial width greater than the first axial width. The lower annular band is configured to deflect upon application of an axial force above a threshold axial force. The tire also includes tire structure connecting the circumferential tread to the lower annular band. The tire structure has a third axial width less than the second axial width.
