One thing that has helped with balancing for me is to get the shop to line up the heavy spot on the tire with the valve stem. If they are marked anyway.
That will absolutely make a huge difference sometimes!
I'd say OP issues are with the tires. My original Nittos started getting pretty bad after the 40K mark. Just installed GY 285 Duratracs and they are completely smooth. OP this may sound off, but have you tried balancing them with a non-roadforce machine? A buddy of mine that has been doing tires for a long time told me that sometimes roadforce is not the way to go on larger more aggressive tires.
My best balance on my Duratracs was done on a Hunter non-road force balancing machine from America's Tire. I believe the model was called Quick Match. I still had all sorts vibration problems when the first America's tire kept doing it on the latest and greatest Hunter GSP 9700 Elite road force machine.
