I am adding a Detroit True-Trac very soon to the front pumpkin and since I'm almost 60, I think I will stay with the 32" tires. I have the auto tranny and I wonder what advantage I would gain with swapping to 4.10 gears over what I have besides a modest boost in off-roading ability. Since my JKU will reach overdrive quicker, you reckon I will get about the same mileage I'm getting right now, which is an averaged 17.5 mpg? I imagine a Rubi owner can answer this one fairly easy. BTW, I am a very modest driver when it comes to mashing the go pedal.
