AIRLESS TIRE

[Subject Matter] To enhance the riding comfort of an airless tire. [0002] [Solution(s)] A spoke connecting a tread ring and a hub is formed with multiple spoke pieces arranged in a circumferential direction. Along a base line extending radially, each spoke piece includes a tread connecting portion and a hub connecting portion, and between those connecting portions, each spoke piece further includes a spoke curved portion that veers off the base line in a circumferential direction. At the coordinates around the tire axis where a perpendicular line extending vertically upward from the tire axis is set as 0°, a spoke piece positioned at 0° is set so that straight radial length (LSb) of the spoke piece under base-load conditions is at least 1.05 times the straight radial length (LSa) under no-load conditions, and curved radial length (LLb) under base-load conditions is at least 1.03 times the straight length (LSb).
