I RAN 235/70/16 Cooper AT3's on steel rims the same size as the pro-comps you are looking at. No issues on my 2014 FDII. I might be mistaken on this point, but I think that after 2012 all Patriots got the same suspension components. So there shouldn't be a height difference between them. If that's not accurate, then as Sandstone said above, you may have to do the pinch weld mod to eliminate some rubbing.
Without a lift, you probably WILL have to do at least the pinch weld mod for the 225/75/16's.
