no need to roll them they clear perfectly... tire selection is "KEY" you always want to look at the tire specs esp the tread width when installed. These are at 7.7" installed on an 8" wheel while something like a Kumho in the same size would be 8.1"
looks nice! Its a pain having to modify the bumper when you get more flush than that. I'm sitting at 17x9.5 +38 in back and was rubbing like crazy w/ 225/45/17 bridgestone pole position. Ended up modifying the bumper mount and mounting it up higher so that the tire didnt hit it. IMO, your setup could be a bit lower, but again thats just my opinion. Great look though.
