ABSTRACT:
A wheel and tire for an aircraft includes a number of wind receiving ledges radially arranged on side surfaces of the tire for causing the tire to rotate by receiving wind pressure before touch-down of the aircraft in a landing position. According to the invention each ledge is formed on its edge with a bead to obtain rotating speed of the wheel and tire proportional to wind velocity, thereby making it possible to design the wheel and tire whose circumferential velocity at the moment of touch-down is as coincident or substantially coincident with the touch-down speed of the aircraft as possible. Each wind receiving ledge consists of a wind receiving tire ledge formed integral with a tire and a wind receiving wheel ledge integrally or detachably fixed to a wheel centrally provided on the tire, thereby enabling the wind receiving wheel ledge to be changed by exchanging the wheel or the wind receiving wheel ledge itself for other wheel or wheel ledge having a different wind receiving area so as to vary the center of wind pressure acting on the wind receiving ledge.
