Yeah I don't think it should be a problem either. This never happened on my stock wheels, on any winter wheels, or on my old breytons which were same size as stock, even with slightly larger rubber. Only ever happened with the 19's. Maybe our problem is different? Or maybe we have the same problem, but it's just more pronounced on your car so it happens even with the 18's. Could it be what GeeRam mentioned below?

That sucks. I've read stories on E90 post and X3 forums, and others have had the issue. Sometimes a new steering rack helped. Other times it didn't at all. Of course I mentioned that last tidbit to BMW and they refused to try to put in a new rack before just blaming the wheels. Ugh.
