Are you lowered? If so, on what?
Those wheels will work just fine. I'd recommend a 225/40/18 tire on all four corners and rolled fenders. The fenders do not need to be pulled and just a regular fender roll will suffice. Not sure why people recommend heavy fender rolling. Either roll them all the way up or not, don't waste your money of a "half-roll" job.
