And this thread is helpful, Thanks.
Intetesting question. My logic would leave me to believe decreased rolling resistance would be likely to lead to better fuel economy, especially in light of this thread. I think that the reason this study would be difficult to produce would be the vast amount of uncontrolled variables. I think the thing to is test a few tanks at each psi (maybe 3 tanks each) and note the variables along with fe of each. This might be easier to acomplish for someone that drives allot of miles or has a low end fe vehicle, as that many tanks is likely to take a long time.
