Explains so much. Outside of the tolerance figures BMW are using in their data for similar wheel vibrations.
F10 example for similar wheel vibrations...

Note: Play at the wheel hub greater than or equal to 0.15 mm is outside the permissible tolerance

(I'll see if I can find any confirmation for the G30)
Becoming even clearer why mounting accuracy is more critical than a simple "just put the wheel on" fit.
