MPG with 35” or 37” and 3.92

[Ironwill]

Those running 35x12.5 or 37x12.5 tires with 3.92 gears... what kind of gas mileage are you getting?? I’m looking to pull the trigger on a 6” lift and 37” tires this week but I’m already averaging a mere 14.7 mpg with stockers. I’m really hoping to stay above 10mpg. Are the 35”s that much more economical than the 37”s ?

Expect about a 2mpg drop or better.
