A wheel and tire assembly for a mobile vehicle in accordance with the present invention includes an inner central rim, a flexible ring mounted on the inner central rim, and a spoke structure extending between the inner central rim and the flexible ring. The spoke structure defines a plurality of cavities and alternating radially extending openings disposed concentrically about the inner central rim and allowing the flexible ring to deflect under load. The spoke structure further defines a plurality of triangular openings disposed at the flexible ring and between the cavities and the inlet openings.

An airless tire includes a tread ring, a hub positioned on radially inner side of the ring, and a spoke structure including polymer material and connecting the ring and hub, the structure including spoke pieces arrayed in circumferential direction. Each spoke piece has a tread connecting portion, a hub connecting portion, and a spoke curved portion between the tread and hub connecting portions, each spoke piece has straight radial length LSb of at least 1.05 times straight radial length LSa and curved radial length LLb of at least 1.03 times LSb when positioned at 0 on coordinate around the tire axis where a perpendicular line extending vertically upward from the tire axis is set 0, LSb is measured along the base line under base-load condition, LSa is measured along the base line under no-load condition, and LLb is measured along a curve of each spoke piece under the base-load condition.
