You might want to search for a shop that knows how to set up their balance machine and are willing to do so. Be aware it will cost more to do it right. That will double or triple the balance time and is not the sort of time that a shop gives away just to sell a set of tires. But worth it, IMHO.
Ask if you can watch the technician work. As the machine spins up you can see for yourself good balance jobspins smoothly without jumping.
This was a process over more than a week. Major chain tire shop. Wheel set up, centered, measured, spun and weighs applied. Spin to confirm and gave new results. Even replaced the centering cone from Hunter. 2nd shop had brand new equipment, still unable. Mercedes shop right on the money first time. Mounted to a hub.
