Interesting and thanks. Yes, you're right - the field gets pretty narrow with that combination. The Pirelli Cinturato P7 Grand Touring shows as a fair all season tire and it's cheap - $130 shipped right now! Hopefully with the market demand growing from PHEV owners with no spares by the time I need tires there will be some more choices.

As a new Energi owner the spare tire issue is on my mind. Having never owned run-flat tires I do understand the general concept thereof and it looks to me like like even after losing all of the air most of them run about another 50 miles at about 50mph. So here's the question: wouldn't that type of tire be almost a no-brainer for this particular car? Furthermore, why wouldn't Ford add them as original equipment? My first thought was cost, though a quick search on Tirerack shows a few Michelin options at or below the cost of the OEM tires. Any thoughts? Maybe I'm missing something here.

Yes. I think this falls into the same category as "Would you buy an airplane from Honda?" http://www.bizjournals.com/triad/news/2014/12/31/honda-moves-closer-to-delivering-hondajet.html?page=all The OTWEM (Over-the wing-engine-mount) is going to add like 20% cabin volume compared to what all of the other manufacturers offer because Honda started with a clean sheet and re-designed the mold. I believe that if Apple took the same due diligence that Honda did it would be a viable product in an unfamiliar product segment. I think Apple, like Honda, will benefit from out-of-the-box thinking. Apple needs to give it a shot.
