35 vs 33 gas milage

[Tufftruck79]

So I just swapped to 35x12.50 on Tues and snapped a pic of dash with the 900+ miles I had on the stock tires/wheels and was combined 16.5 MPG

I planned to post a thread after I had 900 miles on the 35s, but after 300 miles I’m at 14.9 MPG

Thanks and hope this helps

Keep in mind that you added atleast 31lbs of static weight per corner. Even running the same size tires with that much added weight you would notice some difference. Plus the leveling kit reducing aerodynamics.
