my bone stock truck gets 16 mixed driving and an estimated 20 on the highway. both of these numbers are driving like a granny and keeping the rpms below 2000 at ALL TIMES.
this week i have been doing a test:
i've been driving a bit faster, accelerating faster, ect.
i am curious to see what my mileage is when i drive at the same speed as everyone else on the road, if not a bit faster.

2000 Lariat F250 PSD 7.3L 4X4 supercab longbed cab-high canopy (factory stock everything):
25 degrees F 17 @65 MPH
35 degrees F 18 @65 MPH
45 degrees F 19 @65 MPH
Same 45-mile drive (each way) every day, same driver, same load, same habits. I've been told 72 degrees F is the sweet spot and the math works out so far... I've been told to expect as high as 22.

If your at 12 city/15 hiway now - then with 35's I would think you would loose at least 2mpg if not more. That truck has to work harder to get those tires rolling. When I changed to 295's I lost at least 1mpg.

look a little closer, Gordon-o is driving a 2wd, so he most likely isn't running 35's and Tugley is running a 7.3 powerstroke diesel so you can't really use either one of those as a comparison. rjfetz1 is really the comparison you should be looking at, although he is running about a 33? I have had both gas and diesel and I am currently running 35's with a v10, which believe it or not gets about the same mileage as a 04 5.4. and if I were concerned with the mileage,(its not a daily driver) it would be city = crap / hwy = not much better than crap. If you decide to go with the 35's just make sure you get load E tires so you can run the proper air pressure in them which wil help, a little.
