Unlike most ground based transport, aeroplanes don't get their motive force from mechanically turning the wheels. The force comes from an engine which moves air, whether by propellor or turbine, and the reactionary force moves the aircraft forwards. If the wheels were driven instead, then as soon as the plane took off, the force would cease and it would quickly drop back down again.
