I think Darren at MetroMPG.com has the right answer in that link. The best way to find the point of lowest rolling resistance VS tire pressure is to duplicate his experiment on your own car. Every car is different, not all tires behave the same, so try it and see for yourself.
Thanks Sentra SE-R for finding that link, great info!

Maximum rolling distance is the same for all cars and tires; 1/10 of a PSI before the tire explodes. But anymore pressure than that makes rolling distance quite short
