Well....I do not have to much "Tech" input on this... But Right now I have a 4.0 w/ 4.10's and 35's on my Ranger....I have been thinking about going with 4.56's.. So If I do, it could really pay for it's self in gas.? Right now I am getting about 15mpg...It doesent make a hole lot of sence to me,,,But, Heck if I can improve my MPG. i just might me game.Would I even get a Mpg increase going from 4.10's to 4.56?

when you go to a larger tire, without regearing, your vehicle struggles in many ways to do what you want it to. Acceleration will cause more a of gas intake, because your on the pedal a lil more to get up to speed faster, because your engine cannot move them more efficient like they did before. When you regear, it takes a lot of strain back off your drive line. Now you can go with to much of a gear, and loose mpgs on the highway, because youll be running a higher rpm, or you can still go a little bit lower, get some performance back, and not loose as much mpg as you did.
It really comes down to load on the engine for a given driver. There are times where you can actully gain mpg by going higher.. and sometimes going lower. It honestly depends on too many things to give a one size fits all answer.
Anytime you increase mass of the wheels and/or tires you'll decrease milage. Finding the gear ratio to maximize that combo vs your driving style and terain is not easy. And because of the cost it can become subjective in short order!
I'd suggest gearing / tire-ing the truck based on how you want it to perform. Then live with the outcome. If your really wanting better milage stick with stock tires, roll up the windows, and drive 45mph. Or drive something else.

Yes that's about it.
I question whether his really does take the speedo signal off the rear tone ring.
Interesting to note: he went up about 20% in ratio, and got 20% better gas mileage? Highly unlikely that it's a "real" gain. I think it comes from uncorrected data.
