A wheel assembly that includes an outer rim assembly with a first outer rim portion, a second outer rim portion, and a plurality of outer cross members extending between the first and second outer rim portions, a tire assembly secured to the outer rim assembly, and at least a first bump stop assembly. The tire assembly includes an outer main body portion that includes first and second outer side wall portions and an outer contact portion extending transversely between the first and second outer side wall portions. The first bump stop assembly includes a first inner rim portion, a second inner rim portion and an inner main body portion. The inner main body portion includes first and second inner side wall portions and an inner contact portion extending transversely between the first and second inner side wall portions. The inner contact portion is coupled to the outer contact portion.

A non-pneumatic tire includes an inner ring having an axis of rotation and an outer ring coaxial with the inner ring. The non-pneumatic tire further includes support structure extending from the inner ring to the outer ring and a circumferential tread extending about the outer ring. The circumferential tread includes a band layer constructed of a single material and a tread rubber layer directly attached to the band layer.

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 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 an outer ring coupled to the outer rim and defining a closeable gap with adjacent interior portions of the inner rim to define a mechanical stop to limit relative movement of the inner rim and outer rim.

A wheel apparatus for a self-propelled irrigation system has a center portion, a rim assembly, and a support structure disposed between the center portion and the rim assembly. The rim assembly has a plurality of rigid members spaced apart from each other with longitudinal axes that are parallel with each other and equidistant from the axis of rotation. The rigid members are cylindrical with unsupported ends, and a mounting portion between the ends is connected to an outer periphery of the support structure. The rigid members are held in a fixed position relative to the center portion by the support structure. The rigid members are arranged to contact the ground surface to support the irrigation system with spaces between the rigid members allowing mud and debris to pass freely between the rigid members during operation to enhance traction while minimizing mud from being forced out of a wheel track.

A method for manufacturing a wheel hub (300) for a non-pneumatic wheel (100). A sheet (332) of material may be folded, cut, bent, and otherwise processed to form portions of the desired wheel hub(300). The wheel hub (300) may be connected with an annular band (108) through load supporting members (106) that can be selectively connected and disconnected from the hub (300).
