Road force balancing refers to the way the machine turns the tire. On old machines the tire was spun on a spindle and there was no contact between the tire and any surface as there is when you drive. Road force balancing uses a drum to turn the tire like a road surface. This allows for the natural deformation of the tire side wall just like you have when the tire is on the ground.

The computers are more sophisticated and can tell you if the wheel is out balance, if the tire is flat spotted or if the tire is out of round. This is in addition to better balancing.
