Just for fun, I tested 4 space-savers at 70 PSI (above the rating), and they still performed HORRIBLY in terms of rolling resistance. Worse than any other tire I tested that day:

Obviously I'm not saying the same thing will happen with every brand of space-saver tire, but it does show it's not safe to assume a happy & efficient improvement.
