I have 10 inch wide wheels, I rarely go over 55 MPH,

I run 15 to 20 in my 35's , great ride and wear. still get 16 mpg average. If mileage is what you want, get a Prius and park the jeep.

So I aired them down to 35psi, the recommended psi on the door. I'm running Pro Comp Xtreme A/T 305/65/17.

The jeep did ride softer than at 40, but did not seem to roll as easy as when at 40. Given that superchips has improved the overall driving characteristics, I'll probably leave it here for now.
