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 commercial chain block system is disclosed herein including a block assembly including an elongated platform supported by a first-support-leg, and a second-support-leg extending lengthwise along opposing sides of the platform. The first-support-leg and the second-support-leg have a ramp at one end forming a 45 degree angle. The platform, the first-support-leg, and the second-support-leg are configured to support a tire of a vehicle upon a top-surface of the platform and assist in installing chains on tires of commercial vehicles.

A wheel comprising a non-pneumatic tire for a vehicle, such as a vehicle that is steerable and/or otherwise movable by leaning the vehicle (e.g., a bicycle, a motorcycle or another two-wheeled vehicle), in which the non-pneumatic tire may be designed to enhance its use and performance, including, for example, to avoid sudden failure, improve steering and/or other movement of the vehicle (e.g., when the vehicle is leaned and the non-pneumatic tire is cambered), improve ride comfort, and/or exhibit less rolling resistance.

A rolling element such as a wheel and wheel attachment or caterpillar type rolling element for improving support. A rolling element includes: a first support surface formed as a loop configured to roll on a substrate such that a region of the first support surface alternately contacts and separates from the substrate, a first extension running about the loop and disposed about the first support surface, wherein where the rolling element is disposed on the substrate and a load is applied thereto: in a first region of the loop where the first support surface is separate from the substrate the first extension extends beyond the first support surface, and in a second region of the loop where the first support surface contacts the substrate the first extension is deformed so as to form a second support surface which contacts the substrate.
