It is performed through a balancing machine which can only be found at a workshop, where mechanics simply place the wheel on the machine, which rotates it at a high speed. Now, if you know a little about physics you may be aware of centrifugal force. Centrifugal force is created as a result of circular or rotatory motion, and it pushes objects away from the point of rotation. Its magnitude increases with weight of the object and its distance from axis of rotation. After balancing, the wheels are ready to be fixed.
