What's Your Gas Milage and Tire Size?

Just out of curiosity, I'd like to see what the most common milage is and how much of a difference tire size is making on different jeeps.

Feel free to list any engine or gearing mods you have done.

I'll start it off. I have a 2006 Rubicon, 4 speed auto on 265/75 (31.9") and I'm averaging about 15-15.5 city, 16-17 hwy.

My 06 Rubie on 33s with 4 inch lift gets 15 mixed. I have seen lows of 13 and highs of 17 plus. I do not drive fast, 55 to 60 is about it. I had a JK Sport before this TJ and it might have gotten another 0.5 MPG on the same mixed cycle but it was only lifted 2 inches and had 30 inch tires.
