I have been driving on stock Rubicon wheels and tires for about three month. Avg MPG was around mid 14's. Put 35" on Monday and MPG is now in the mid 11's. I also have the Procal Turner and changed tire size to keep speed-o at correct speed and turn off TPS sensors.

The accomplishment here is 2-fold:
1) Get great gas mileage for driving to work
2) Stretch the life of those ridiculously expensive 35's by using them sparingly

In reality I don't think you will ever take the 35s off once they're on.

I know how you feel. I run 37's humvee beadlocks wheeling and swap back to my 35's sometimes just to save the weight and it does help the MPG.... But it gets old swapping them out for sure.
