It only makes sense lower gearing and big tires are significant factors when it comes to mileage. SAS tires are heavy folks and the energy it takes to turn them isn't free. This is why the lower trim levels are rated 20 - 22 and SAS 17-17, a significant difference in my option.Apologies if this has been covered already and I just didn't see it, but anyone have any idea of what the impact will look like on the swap on OBX to the rear locker? As far as I can understand the stock for OBX is 3.73 ratio (so presumably that's the numbers that are on page 1 of this post), but the change to the locker (for non SAS) looks like it's 4.27. I'm sure that would impact MPG in some way shape or form, but I don't know enough about this stuff to know how much.
