Ed Wright says there is much to be had with his program, a couple of guys have told me it is worth 2-3MPG.

I know for a fact my tires are too short, an my gear too low. I can drop 200-400 RPM and pick up 2MPG.

I'm actually looking at converting to taller medium truck tires, for more load and towing capacity, and lower RPM.
