I understand balance. But what is road force?
Road force is where the tire is chcoked up on a special balancer that has a roller arm that applies pressure to the tire. Then the tire spins and sensors measure the movement and forces of the tire. The machine will display a number in lbs, if it is to high you pull to other measuring arms down and this will measure the rim. It will then calculate where you should rotate the tire on the wheel for the best possible balance. The idea that two imperfect surfaces can make a better one. It does a good job with getting rid of vibrations. If you have had tires balanced time and time again and still have a problem, they may just need to be road forced.
That is why I recommended the michelins to the op, cause they typically have the lowest road force right off the bat no need to do anything but balance. They also seem to stay round through the life of the tire. I see it at the shop car comes in with a vibration and you spin the wheels on the car and look at them and they look like an egg going round. no amount of balance or road force will fix that.
