I am in the process getting a 6" suspension lift, 3" body lift, 4:56 gears and some 37" tires on my 4.7 dodge QC.

What type of gas mileage can I expect to get with this setup?

Can I get a lot better gas mileage if I go with a 35" tire, or does it make little difference in comparison to 37's?

Do I lose any reliability with truck doing all the above mods?

Is there really anything I can do to get some where around 15mpg with the above setup?

Thanks for your replys:thumb

 

My Power Wagon gets around 10MPG with 35" tires and 4.56 gears. I would not recommend 37" tires on anything less than a 3/4 ton.
