A wheel (1) has a wheel rim (10), a positioning lid (20), an inner tire (30) and an outer tire (40) and a sealing loop (50). The wheel rim (10) has a disc (11) and an outer rim (12) mounted on the disc (11). The outer rim (12) has multiple recesses (17) and a flange (13) extending from one end of the outer rim (12). The positioning lid (20) is attached to the outer rim (12) and has a flange (23) formed on an outer side of the positioning lid (20). The inner tire (30) is mounted around the outer rim (12) and has engaging blocks (31) held respectively inside the recesses (17). The outer tire (40) is squeezed between the flanges (13,23) on the outer rim (12) and the positioning lid (20). Accordingly, to replace the tires (30,40) is rapid and convenient. |
