A pneumatic tire (1) includes an inner cylinder (6), an outer cylinder (4), and a connecting member (3), in which the outer cylinder (4) and the connecting member (3) are formed to be 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 (1) 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.
