You have to remove the rear caliper to get more roll done. At first I only rolled enough on the top thinking it'd be all good. I went up an incline and my tire was rubbing. The sharp fender slided a small string out of my left rear tire.
I'd say if you run 245 or smaller tire, you can get away with a minor roll.
