A motor vehicle (100) has four centreless wheels (10) drivable for use on the ground and four propellers (16) rotatable within the open centres of the wheels (10) for use in the air. The wheel-propeller assemblies (10, 16) are carried on mounting units (14) secured to a frame (12). The mounting units (14) are rotatable on the frame (12) and the wheel-propeller assemblies (10, 16) are rotatable on their respective mounting units (14), in each case by means of servomotors, to convert the vehicle (1009) from its ground mode shown in FIG. 1 to its air mode as shown in FIG. 2, and also to turn the wheel-propeller assemblies (10, 16) so as to steer the vehicle (100) when on the ground and to tilt the wheel-propeller assemblies (10, 16) so as to direct the vehicle (100) when in the air.

An aircraft wheel includes a rim that is secured to a central hub defining an axis of rotation of the wheel. The wheel includes one or more driving pins that extend from the hub, projecting in a direction substantially parallel to the axis of rotation of the wheel so as to cooperate with a driving member for driving the wheel in rotation. The driving pin is distinct from bolts assembling together parts of the wheel.
