Hi I just picked up at set of 17 used rims for a great price. I'm not sure what's the biggest size I can run without doing a little trial and error lol. I'm hoping some of you guys are running 17's and know the answer. I've already read through all the tire post and haven't seen anyone say they're running 17's or the size if they are. I'm looking at running 205/50R17 or 215/50R17. If I need to drop the sidewall down to a 45 or 40. I will but I'd prefer not to if possible. My car has stock suspension. Thanks in advance to any replies.
