I would go with 20" instead of 19". Got my F11 last year and wanted to go with 19" as i didnt wantede so "big" wheels, but there is no argument in terms of price to go with 19" instead of 20" and my tirepusher keept pushing me to go with with 20" and im glad i did
and as many others here ditch those runflat, they are in general just an aweful tire to drive on.
8,5x20 ET35 in front and 10x20 ET35 in the rear, mounted with Falken Fk-453 i 245/35/20” and 285/30/20” and no scrubbing what so ever.
