The semi-pneumatic tire (10) further includes a pneumatic portion (300) coupled to an inner circumferential surface of the non-pneumatic portion (200) and provided with a space into which an air is filled, and bonding layers respectively interposed between the tread portion and the non-pneumatic portion and between the non-pneumatic portion (200) and the pneumatic portion (300). The non-pneumatic portion (200) includes a band portion including an inner band coupled to an outer circumferential surface of the pneumatic portion (300) and an outer band spaced apart from the inner band and surrounding an outer circumferential surface of the inner band, and spokes provided between the inner band and the outer band to connect the inner band and the outer band.
