For whatever its worth:
I have 235/35/19 front and 275/30/19 rear tires on my 335is, absolutely no rubing. In fact the front and rear from measurement clearance show our 19" rims can max out at 245/35/19 front and 285/30/19 rear with no rubing.
Now it may depending on the type of tires though. I have Nitto NT 555.
