A non-pneumatic wheel (100) including a hub (300) and a non-pneumatic tire (102), as well as a method for mounting the non-pneumatic tire (102) onto the hub (300). The hub (300) is formed, with grooves (318) that receive the radially-inner ends (110) of spokes (106) of the non-pneumatic tire (102). To secure the tire (102) onto the hub (300) during assembly, the grooves (318) with the radially inner ends (110) of the spokes (106) received therein are pulled radially inward to decrease the diameter of the hub (300) and increase tension in the spokes (106).

A pneumatic tire includes an inner cylinder, an outer cylinder, and a connecting member. The outer cylinder and the connecting member elastically deformable, and the thickness of the thickest part of the outer cylinder is thicker than the thickness of the thickest part of the connecting member. When the outer cylinder is pushed by a protrusion and deformed toward the inside in a tire radial direction, at least a part of the connecting member, which is positioned between the protrusion and the inner cylinder, and other connecting members adjacent to the connecting member in the tire circumferential direction abut each other. When the non-pneumatic tire is mounted on a vehicle and travels on a flat contact plane, a gap is secured between the connecting member positioned between the ground plane and the inner cylinder and other connecting members adjacent to the connecting member in the tire circumferential direction.
