I am considering a 6" lift with 37's for my 05. Would like some feedback on how your fuel mileage was effected after the lift/tires. Thanks in advance.

 

For my 06, 4.5 inch lift and 35s, I went from about 17 average to 15 average. I would imagine you will see more of a drop with the bigger lift and tires you are looking at.

 

My lift has been on long before I even cared what my fuel mileage was....

Just remember , the higher you put that brick in the air , the more power (and FUEL) it will take to move it.

If I can stay around 60-63 mph , I can get around 16.5 mpg (hand calaculated), if I`m running 80.....it`s more like 12-13.

Around town , I don`t think it makes much of a difference.
