Well I wanna do 265-70-15 tires on the 2wd with the 3" lift..Will running AT's as apposed to street tires hurt millage that much?

 

I had a 1-2 mpg drop running bfg at's in 265 over bridgestone revos in the same size.

Depending on how many sizes your jumping you might need to plan a regear.

If fuel economy is on your mind a lift and big tires are the opposite way to go.

 

Im fully aware of that but im going to lift it and so it all right and want to maximize my millage of the setup.

 

Ive got 265/75r16 on my truck 4.0 auto 4.10 gears and %100 city driving with a heavy foot im gettin about 11-12 and thats in the cold with a camper shll and a bunch of gear in the back. Ive got good year duratracs for tires BTW.

 

Where can I see pictures of your truck? we're running the same tire size

i get about 50-60 miles for each 1/4 and I am pretty easy on the throttle. I think it drinks fuel alot faster when on the highway
