Road force is the best. It's balancing the tire in the distorted mode, the same way it goes down the road. Road force if done properly, the run out of the tire, the run out of the rim, in opposite matching is on where to mount the tire on the rim. It is the only machine that will tell a bad tire. With all 4 tires done it will tell you where to put each one on the car. With a good front end-alignment, and 4 tires road forced going down the road 25 mph or higher, you will not feel the tires or the road. It will feel like you are on a magic carpet ride. This will make front end parts last longer from not beating them up.
