NON-PNEUMATIC TIRE

In a non-pneumatic tire (1), the plurality of connecting portions (4, 5) comprise first connecting portions (4) extending in such fashion as to be directed from a first side (D1a) in a tire width direction (D1) of an inner annular portion (2) toward a second side (D1b) in the tire width direction (D1) of an outer annular portion (3), and second connecting portions (5) extending in such fashion as to be directed from the second side (D1b) in the tire width direction (D1) of the inner annular portion (2) toward the first side (D1a) in the tire width direction (D1) of the outer annular portion (3), and at least one of the plurality of connecting portions (4, 5) comprises a main body portion (6) having a width that is constant or that increases in tapered fashion by a constant ratio as viewed in the tire width direction (D1), and an reinforcing portion (7, 8) that connects an end in a tire circumferential direction (D3) of the main body portion (6) and the annular portion (2, 3).
