Stock F250 should have 3.73 gears and with the bigger tires it will make a difference in fuel economy (or lack thereof ).... That said, I wouldn't think it would make that much of a difference...

I get better mileage then that pulling my 5th wheel at about 11,500 extra pounds... My truck usually gets between 15.5 and 16.5 around town and is totally stock, tires and all... I got between 12 and 14 towing my 5th wheel up to the Grand Canyon from Phoenix... There is a BUNCH of uphill involved on the way up so I'm thinking 11 sounds way low for just bigger tires... Hopefully someone with a similar setup can tell you what they are getting...

you should clean that air filter at every oil change. or every 5k if you are doing 10k oil change intervals.

fuel filters should be changed every 10k so you are almost 20k over.

this could be major contributer to your poor fuel mileage.

I'm experiencing something very similar with my 2004 4x4. It's completely stock, turbo was just replaced about 1500 miles ago because the old one had failed.

My tire size is 285 75R16, which was the next step up from the 265's it came with. My mileage is consistently hovering around 10 mpg, no matter how I drive it. I can baby it or stomp on it, freeway, in town, it doesn't make a difference. While I give the rig an A for consistency, it is rather frustrating hearing other's post their mpg's.

The air filter was replaced just after the turbo was done. I replaced both fuel filters less than a month ago, and the oil was just changed about 300 miles ago. Currently I'm running dino oil, but will be switching to synthetic, just couldn't afford to get the stuff I wanted last time around....

I'm at the point now where I'm almost ready to take it into a mechanic that is very reputable in the area here to see if they can find anything, but I don't want to spend money without needing too.

I've scanned the computer, no codes are being thrown, etc. I have the zoodad mod, but other than that it's factory. Any ideas?
