Okay new to the truck scene and just bought a 2014 ram 1500. I am wanting to get a nice size lift and tires but not destroy gas mileage as it is my daily. I understand it's going to lose some but I am wanting 20x12 and 33's or 35s. Ans maybe a 4 or 6 in lift. I have 3.92 gears pretty sure so how much will that affect the gas mileage.
