I was trying to see how wide i could go on my 2k GS. My tires started to ball so i went from my Falkens 512's 205/45 17 to the ones i have now which are the same series 512's but uped the width to 225/45 17 and now i rub on the rear fender, in corners everytime i get more than 2 people in my car. So i would assume that never get anything more than 215's unless your going to mod your fender out. The good thing is my tires are almost worn again. So i can finally fix this dam problem.
