front is 26.8", too tall

not sure if the room in the front fenderwell changed from 435xi F36 to 440xi F36 but this member has 19" with a 26.4" tire diameter and the front left tire rubs the fenderwell liner turning tight turning transitions. maybe it's just his car and/or yours could be different but with oem 26", deviating 0.8" to 26.8" is too much for me regardless.

I know I'm comparing 19" to 20" and I'm no tire expert by any means, but I'm on stock hight and suspension and I just put a 19" x 10" et 45 wheel on the back of my car with a 265/30 tire and I'd be concerned a 275 "might" rub during hard cornering, passengers in the back and certain dip type bumps.
