37" tires and 20" wheels
I have a 5.4L 4x4. Im thinking about going with 37" tires and 20" wheels. My only concern is how much will MPG go down? Im running 35's with 16"s right now. Will I need to change my braking and gear ratio to accomidate the tires and wheels? Thanks!

New gears would highly be recommended if you're going to go higher than 35's. I'm running 35's on my truck right now and I regeared form the stock 3.55's to 4.56's and regained every ounce of lost power.
