In-wheel parking air-castors

When parking you press the right/left or off button, which releases air from bottom of wheel, and car is "hovered" albeit a small distance, into or out of parking.

In order to accomplish this, the mid part of tread lug on tubeless wheel, has air outlets controlled by driver. Air pressure is entered to the center of the wheel, under same control. To move right or left, different tread-lugs are enabled. (Ones on right to go left, and vice versa). Air enteres the tire from center, while leaving it at the cogs. Any extra pressure is automatically removed, once "drive mode" was selected.
