So I was able to fit 19x9.5 ET22 with Michelin Pilot Super Sports in 265/30/19 lowered on ST coilovers.
They were originally rubbing. You need to grind down that piece of metal at the edge of the fender where it meets the bumper. When you run your finger in that area it will be obvious what I am talking about.
Now I have NO rubbing with a tire that has a very tall non rounded sidewall on M3 fitment wheels!
