Durability is an issue as well.
And when Darin / MetroMPG mesured the rolling distance with 4 space savers, the results were far from impressive : they were obviously not built for low rolling resistance.
Thinness will only gain you so much - bad RR can easily make things worse.
What you want for improved fuel consumption is a light, narrow, low RR, high LI tyre that can be pumped up to high psi.
