255/30/19 or 265/30/19

I recently order new wheels (19 inch APEX ARC-8) for my 2010 e90 335i M sport and I would like to know what size tires should I buy for the rear that would not rub and no fender modification? My car is lowered on Eibach Pro Kits w/ Koni Yellow. Wheel size: 19x9.5" ET33



Here are my choices in sizes: 255/30/19 or 265/30/19? Thanks in advance.
