I'm running 17x9+40 rears on 255's and no rubbing at all. I did my guards myself so they ain't even that flat as well. I'm gonna re-do em caus I wana go fatter LOL
When I was running the 17x9+44 work emotions I didn't roll nothing and it only scraped on big bumps, and it was scraping the rear bumper not the guard :D
