A non-pneumatic tire assembly includes a non-pneumatic tire. The non-pneumatic tire includes an inner circumferential ring and an outer circumferential ring defining an annular space and a cylindrical space inside the inner circumferential ring. A plurality of partitions connect the circumferential rings within the annular space. A ground-contacting tread is located on the outer circumferential ring. A rim, including a plurality of pieces, is located within the cylindrical space. The non-pneumatic tire assembly further includes a hub that is removably connected to the rim.

A two-piece rim and tire assembly. The tire is held to the rim by fasteners extending through flanges integral with the tire main body and then into the rim. Further, the outer edges of the rim clinchably mount the tire main body thereto. A flexible overhanging portion extends outwardly of the tire main body minimizing dirt and mud accumulation on the tire and rim. A bearing is held within the rim by a ring.

An adjustable portal box assembly for selectively mounting a wheel to an off road vehicle in either of two positions. The assembly includes a mounting plate mountable to the suspension of an off road vehicle, and a portal box is mountable to the mounting plate. The portal box includes an input shaft opening for an input shaft, and an output opening for an output shaft. The portal box is mountable to the mounting plate in a first position in which the output shaft is positioned to extend the wheelbase relative to the input shaft, or in a second position in which the output shaft is positioned in vertical alignment with the input shaft.

A materials handling equipment has blades of a lifting fork wherein each of the blades engages a blade wheel that moves between a retracted position when the blade is lowered and an extended position when the blade is raised to lift and support a load. The blade wheels have a plurality of tires linearly aligned on a common axis, the tires each having a circular circumference and a sinusoidally varying peripheral surface. The sinusoidally varying peripheral surfaces have relative peaks and valleys uniformly spaced around the circular circumference wherein the peaks and valleys are mutually nested.

A tire rim structure including an annular inner ring provided on the inner ring of a tire body and a circular outer ring provided on the outside of the tire body, fixedly connected to the annular inner ring, and formed by stamping. The annular inner ring includes an annular inner ring body formed by extrusion, an annular left ring provided at one side of the annular inner ring body and formed by extrusion, and an annular right ring provided at the other side of the annular inner ring body, connected to the circular outer ring, and formed by extrusion. A shaft hole is provided at the middle part of the circular outer ring.

A bicycle wheel has a wheel frame. The wheel frame is a hollow and annular frame and is composited by multiple equally sized wheel bars. Each one of the wheel bars has two halves connected to each other to form the wheel bar, and each one of the two halves being made by laminating, heating and forming a thermoplastic prepreg. The equally sized wheel bars are connected to each other to form the bicycle wheel.
