I know this has been already mentioned several times, but just want to share my experience. I bought a set of new tires (255/35/19 and 275/35/19 PSS) and figured out that the fronts rub on full lock.
I ordered updated fender liners and everything is fine now. No rubbing at all, so if you hesitate, whether to do it or not, it is my experience that with the updated fender liners it works and doesn't rub.
The only downside is that BMW refused to replace them free of charge, but they weren't expensive (100 EUR), though.
