A wheel assembly includes a wheel base, 12, and a side rim, 14, disposed about the wheel base, 12. A recess, 38, is formed on an inside surface, 36, of the side rim, 14. A cavity, 20, is disposed between the wheel base, 12, and the side rim, 14. An air seal, 18, is disposed between the wheel base, 12, and the side rim, 14. A locking mechanism secures the side rim, 14, in position around the wheel base, 12. The locking mechanism is configured to prevent the air seal, 18, from disengaging with the inside surface, 36, and allowing air to exit the wheel assembly between the wheel base, 12, and the side rim, 14, with the locking mechanism is properly installed. The locking mechanism is also configured to permit the air seal, 18, to disengage the inside surface, 36, and allow air to exit the wheel assembly between the wheel base, 12, and the side rim, 14, with the locking mechanism is not properly installed. |
