How to Use Balancing Adapter for the Power Spoke | Corona Wheel

Has anyone had to use the plastic balancing adapters to balance their Power Spoke/Corona Wheels after a tire change? My new tires vibrate now at highway speeds and I suspect that it’s because the tire shop balanced the wheels with the asymmetric cover off. I’m assuming that they need to use something like this: https://www.turnermotorsport.com/p-24876318-adapter-power-spoke-corona-wheel-set-of-four/. But it’s not clear if you just need one to balance each wheel or are they designed to be placed on your wheels after mounting and balancing to re-balance.

Any ideas?
