My dad has a 2005 325it Sport Package. He messed up the original 17" wheels & needed tires so I lent him my set of 17's. Now they're all curbed up as well. I have another set of BMW Style 268s which measure 16x7 ET31. I know I can run 225/50/16s, but I'd like the most protection from curbs as possible for his driving style. Can I get away with 245/50/16s without rubbing? Car is all stock.
