Wondering what type of real world MPG experience anyone has with rims and tire sizes other than stock for daily use and towing? Any reccomendations?

 

with 3.55 i average 18-20 highway 13 around town and havent towed yet only 1500 miles but it seems to be getting better

 

Plus you love alot more than your 6.4

 

Haven't done anything with the ford yet, but on my yukon XL, when I went to ten ply tires VS the soft originals, I lost about 1.5 MPG. and that was with same sized tires.

 

I have 20" tires with the 3.55 ELD rear end. I get between 18 - 21 MPG highway (I have seen better but consider it circumstantial such as long downward slope with the wind at my back, etc.), 17 - 19 MPG rural, 15 - 17 MPG city (suburbs not stop and go like Chicago, etc.), and 11 - 13 MPG towing about 14K pounds. Time of year, speed, tire inflation, seasonal fuel blend, number of regens, use of 4X4, etc. all have an impact on the mileage.
