A non-pneumatic tire including an inner cylinder that surrounds an outer peripheral surface of a metal rim from an outside in a tire radial direction, an outer cylinder that surrounds the inner cylinder from the outside, and a plurality of elastically deformable connecting members that connects an outer peripheral surface of the inner cylinder to an inner peripheral surface of the outer cylinder. The inner cylinder is made of a synthetic resin material. A pair of holding flange portions is formed on the outer peripheral surface of the rim. The rim includes a first split body and a second split body. A size of the inner cylinder in a tire width direction is greater than a distance between inner surfaces, which face each other in the tire width direction, of the pair of holding flange portions. The inner cylinder is formed to be elastically deformable in the tire width direction.

A wheel assembly includes a mounting plate for attachment to a rotatable axle, a plurality of elongate friction members for engaging a tire assembly, a plurality of first angular flanges extending radially outward and circumferentially in a first direction from the mounting plate, and a plurality of second angular flanges extending radially outward and circumferentially in a second direction, opposite the first direction, from the mounting plate. Each elongate friction member is disposed axially between one of the first angular flanges and one of the second angular flanges.

A wheel assembly comprising a wheel disk and a tread member disposed around the wheel disk. The wheel disk can have a substantially conical shape when in an unloaded state, but be flexible such that it can deform under load to optimize and/or maximize contact area between the tread member and a driving surface.

The present invention is directed to airless tires. Exemplary airless tires include a hub configured for attachment to an axle and includes a hub support extending away from the hub. Such exemplary airless tires also include a heel configured around the hub and connected at a distal end of the hub support, whereby the heel includes an elastomer base oriented in a ring around a circumference of the hub support. Such exemplary airless tires also include elastomeric tubes extending radially outward from the heel. Other exemplary airless tires include a centerless hub assembly configured for attachment to an axle and a heel configured around the centerless hub assembly. The heel in such exemplary airless tires includes an elastomer base oriented in a ring around a circumference of the centerless hub assembly. These other exemplary airless tires include elastomeric tubes extending radially outward from the heel.
