Interesting results, I got similar results from my data this weekend.

Anyone have any data for tires used only in streets?

To get better MPG you have to reduce the surface area, basic physics tells us that running higher pressures will make the tire deflect outwards in the center thus giving less resistance and wearing that part of the tire more.
Regardless of construction everything deflects when you apply load.
