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