    Abstract: The invention is a high-efficiency wheel product for use with various ground vehicles. The product is designed to provide rolling support to the vehicle and to accommodate various surface conditions, for example, smooth pavement, rough pavement, potholes, dirt roads, and other conditions. The wheel product includes a multi-chambered pneumatic tire designed to minimize energy loss between the tire and a rolling surface by substantially reducing tire flex, a main source of energy loss in ground vehicles. Additionally, the product can reduce the need for conventional drive train elements such as shock absorbers.

  • Publication number: 20020100529
    Abstract: A weight (18) is set into the lower portion of an annular space (34) in a tire (16). The weight (18) may be a precast concrete member shaped to fit into and extend chordwise of the annular space (34). The weight (18) is wider than the distance between the tire sidewalls (24, 26). When inserted into the tire (16), the weight (18) pushes the sidewalls (24, 26) apart and flattens the bottom portion of the tread (32). The weight (18) at the bottom of the tire (16) and an air space (48) at the top of the tire (16) act together to hold the tire (16) in a substantially upright position. Corrodible iron inserts may be added to the tire (16).
