Most likely problem with the tyres. They all need to have an "unbalance" below 3kg (max) according to BMW after the road force balancing.
From what I could observe in the road force balances I've seen, the machines are not that precise and the G30/G31 needs the wheels to have like a "perfect" balancing not to vibrate. At least this is my experience with Pirelli Cinturato P7 run flat 18" tyres... I would avoid this tyres as I'd to return several because they did not allow for this "perfect" road force balancing.
In my case, I've complained to BMW and after many, many tests it improved, but I'm convinced it will come back with time, because its impossible not to hit a hole in the road and progressively start to unbalance the wheels.
Good luck!
