I fought with this for years until I read an article on "match mounting" wheels. I used this information and have not had an issue since.
In short, it is mounting the wheel/tire combination and finding the high spot on the tire, then removing and rotating the tire one lug/pin at a time until the high spot is at minimum. Then the lug/pin can be marked along with the wheel to enable easy matching afterwards when removing the wheel.

This technique made mine as smooth as glass. The light weight and the wide tires on these vehicles seem to exacerbate the problem.

This was all after balancing multiple times on various machines "road force etc..." and new tires and wheels without success. Had a wobble that would come and go depending on when I went around a curve. It was worse at speed. At times it was almost gone but would come back after going around a corner. The tire place told me it was one of my wheels. It wasn't until I bought new wheels (which were perfect) and tested runout without tires that I realized the hubs have a small amount of runout along with the tires that was causing the problem. In my case it wasn't really the hub, but the studs were slightly off center.
