Double check your door for the OE tire size. Those would be large OE tires for a 4cyl. I would guess in the range of 205 or 215's were what came on it.

The 4cyl. does require quite a bit of gearing to make anything happen. I would check the rear end ratio to see how bad it is. Your Dana 30 up front will go to 4.88.

I would be tickled pink if my Jeep got 20mpg

Happy Jeepin.
