Hi
I have the the same problem. Vibrations starting from 120km/h
I am currently on Bridgestone LM005 245/45-18.
Road force shows all wheels under 4.5kg
I found this site that appears to be from BMW stating which tires each model is tested with.

Seems that only very few tires are tested with the car.
I will change my Bridgestone to Michelin Pilot Alpine 4 on monday and hopefully the problem is then resolved.
Best regards Bo
