The logic is my kid is considering buying one but doesn’t want to spend the money on the SAS package and asked if I can make it look the same, but I don’t want it to end up getting 13 mpg. Does that help??
The larger diameter heavier tires make the biggest difference in fuel mileage. The 2.7 is killing you as well. We have two 2 doors with 35 inch tires. One is the 2.7 and it gets an average of 19 over the past three years we’ve had it. Our other is a 2.3 7 speed and it gets a little over 21 average for the last year that we’ve had it. Ifyou want better fuel mileage get some 32 inch tires that are as light as possible and you’ll see a dramatic improvement. Easy on the throttle, keep your speed down, and coast to stops as much as possible and you’ll get much better fuel mileage no matter what your tire set up is.
This. my 2dr Big Bend on stock 32s pulls 23/24 freeway if I baby it. I got tired of that and still get 21 just driving it however I feel. But it certainly doesn't have the same look as a sasquatch.
Not as much as you'd think. So far, out of everything I have done - lift affected MPG the most. Tires, a bit. Gearing - barely noticable.
Over the years I've lifted a few vehicles and gone up inches in tire size. I always noticed about a 1 mpg drop for tire size increase and another 1 mpg drop with a lift. I also lose about 1 mpg when I put my rooftop cargo box on the roof too. Rolling resistance and aerodynamics are the big killers for sure.
