noob question on gears and mpg

Im sure its been posted many time before but I suck at search function.

What is the stock gearing on a 07 xl 2.3 2wd manual?

I just went from 225/70/15 to 30/9.5/15's and Im trying to figure some things out, such as what kind of drop in mpg's I should expect.

I realize I need gears in a 4 cyl to move the bigger tires, but if Im at 3.73 already, I think Ill be fine. Plus, going from 27.4 diameter to 30 tires, I need to compensate for the 1.0 to 1.1 difference in the odometer. 100 miles actually equals 110 miles right?

Anyone with same setup, let me hear your input.
