Claim:
1. A non-pneumatic tire comprising: an attachment body attached to an axle; a ring-shaped body configured to surround the attachment body from the outside in a tire radial direction; and a plurality of connecting members disposed between the attachment body and the ring-shaped body in a tire circumferential direction and configured to displaceably connect the attachment body and the ring-shaped body, wherein, when the tire comes in contact with the ground, the connecting members are deformed by a compressive load in the tire radial direction, and the attachment body and the ring-shaped body are deformed in the tire radial direction, among the plurality of connecting members, the connecting members disposed between the ground surface with which the tire comes in contact and the attachment body abut other connecting members neighboring in the tire circumferential direction, and a plurality of connecting members neighboring in the tire circumferential direction in the plurality of connecting members abut each other in the tire radial direction and at least some of the abutting portions overlap along the ground surface in a side view of the tire when the tire is seen from a tire width direction and in the side view of the tire in an idling condition, when an angle formed between a line segment AB connecting an outer end A in the tire radial direction the of the connecting member and an inner end B in the tire radial direction and a line segment AO connecting the outer end A in the tire radial direction and the axle O is θ0 (°), a length of a line segment OA is R (mm), a length of a line segment OB is r (mm), θ0=k×(r/R), and an angle formed between the line segment AB and the line segment OB is θ2 (°),
