This setup will not work properly with xDrive. The wheel diameter between the F/R is too great and will cause issues with the transmission. In my case, the transmission was not shifting smoothly and after further research,some references suggest to keep the difference in wheel diameter below 3%.

I went with 245/40-19 in the front to keep the % difference as close to OEM stagger as possible.

I have a slight rub when turning on the driver side front inner wheel liner where it protrudes for the side view camera and park assist sensor . I am lowered ~0.5".
Are you running 275/30 for the rears?
