Please guys don't say rolling in the fenders or what not. I have 95 V6 with Tokico and Eibach setup which supposedly gives 1" front and back since it's a V6. I had 225/45/17 with no problem before. I am going to 18" in the next two weeks and need to know 110% what is the widest and thickest I can go because I live in NYC the city and millions of potholes out there! Can I go 225/40/18 or even 235/40/18 without rubbing? Or just go 215/40/18 to be safe?
