I installed the new tire this evening. It went on the rim easily, as had the previous. Just for gits and shiggles, though, I decided to try seating it with just the floor pump, something that I've never done. After the first couple of strokes, I didn't think it was going to happen, but then I noticed the tire filling out a bit more with each pump, despite all of the hissing. The encouraged me to pump a bit manically. The tire kept hissing, but also kept filling out until both sides finally snapped in to place at the same time - sweet!
