Non-pneumatic tire

A non-pneumatic tire comprising a support structure for supporting a load from a vehicle,

• wherein the support structure includes an inner annular portion, an outer annular portion concentrically provided on an outer side of the inner annular portion, and a plurality of connecting portions which connect the inner annular portion and the outer annular portion to each other and are provided in a tire circumferential direction independently of one another,
• the plurality of connecting portions are configured such that elongated plate-like first connecting portions and elongated plate-like second connecting portions are arrayed along the tire circumferential direction, the first connecting portions being extended from one side in a tire width direction of the inner annular portion to other side in a tire width direction of the outer annular portion, and the second connecting portions being extended from other side in the tire width direction of the inner annular portion to one side in the tire width direction of the outer annular portion, and
• in each of the first connecting portions and the second connecting portions, a plate thickness is smaller than a plate width, and a plate thickness direction is oriented to the tire circumferential direction, and
• each of the first connecting portions and the second connecting portions when viewed in the tire circumferential direction includes a reinforcing portion on a tire radial direction inner end portion or a tire radial direction outer end portion, the reinforcing portion being made larger than a plate width of a tire radial direction center portion, and a sum of a surface area of the tire radial direction inner end portion and a surface area of the tire radial direction outer end portion including the reinforcing portion is equal to or larger than a surface area of the tire radial direction center portion.
