I'm running 8.5 ET39 with 225/35x19 fronts and 9.5 ET48 with 255/30x19 rears on mine with no issues at all. In fact the rear could probably take a 5mm spacer and be bang on fitment-wise.
Tyres will also play a part as there are certain brands that run great bit "rim protection" mouldings in the sidewalls which may cause fouling of the arches or the suspension components....
