OT a bit, but since you two are here...
Is there an issue with stock height E90s running a 255/35-19 up front in terms of diameter? Meaning does this rub the fender liner, either in front of or behind the tire, when turning the wheel through its arc? (I'm thinking here of my daughter's E46 zhp when running BFG R1 245/40-18s all around and how that diameter increase from stock 225/40 caused some minor rubbing due to it).
