I like Road Force Balancing but have a couple of thoughts.
1. The tech gets a number after they Road Force balance the tire (in lbs). If it is a "high" number, that equates to more vibration. Tires & wheels that are larger and heavier (and cheaper) generally result in higher lbs of force and more vibration. For T4R tires, I would like to see this number under 30 lbs and prefer 20 lbs or less if possible. Note that in the attached video, they get a number of 15 lbs on one tire and proceed to do matching to reduce it - they are looking for 10 lbs or less. Lots of controversy over the max on this number and no one (manufacturers or installers) will give you a "spec" because it can bring into question the acceptability of the tire.
2. The real advantage in Road Force Balancing is to be able to match the tire to the rim (see attached video). This requires the tech to mount the tire, measure the force, unmount the tire, move it to the correct position, remount, balance and measure the road force. If the number is "high", do it again. If the number cannot be reduced, there is a problem with the tire or the rim. Ask ahead of time if the Road Force Balancing includes matching, tell them if you have an expectation regarding a maximum number and request that they document the final (after matching & balancing) Road Force lbs of force for each wheel. Prepare for a robust discussion.
3. Lots of effort to do this correctly. Also, the procedure is more complicated and your standard tire tech likely does not know how to use all the capabilities of the Hunter Road Force balancer.
4. I really don't like to have tires installed that are more than 6 months past manufacture. There only good for 6 (or so) years so if you don't put a lot of miles on your vehicle, installing old tires is costing you money, Installers will say that the time in the warehouse doesn't count but if you go in after the 6 year limit and need your tire patched, many installers will not do it due to liability. Ask ahead of time regarding the date codes on the tires that they will be installing.
