Gary I run 255/40-17 Kumho Victoracers on 17x8.5 SSR Comps at et35. I rub very slihjtly at full right lock on the front right. I do have some extra venting for my Happersized oil-cooler that causes this slight issue. No problem with any of the 2 other 17x8 rims and 225 or 244/40-17 tires. HTH. Hap, feelin cool in Everboost if i can get back ther, Maguire
