from what I have read you should be around 19-22 mpg on the higway depending on how you drive. Tires dont really matter much if you go with 35's thats only a inch bigger then stock

35's are 2 inches taller than stock, but they still don't make that much of a difference. If you stay with stock or 35's, you should see pretty decent mileage on the interstate if you keep it under control. I usually run 70-85 mph on the interstate and get anywhere from 16-21 mpg. I drove from Kennesaw, GA to Hilton Head Island, SC tonight running 75-90 mph. I filled up in Kennesaw, drove 5-6 miles before leaving, left to head to South Carolina, pulled off the interstate about a mile to eat, back on the interstate and drove 316 miles. So that is around 322-323 miles. I have about a 1/4 of tank left. I would say thats pretty good driving 80 mph 85% of the ride.

Honestly, there have been many threads like this. Tuner or not there is such a wide variance that it's not worth considering until you get yours and see what it does.


I can tell you that it was not a consideration when I got my truck but I am surprised at the empty mileage I get. As far as towing I believe it is competitive with any new model out there. If I was towing all the time I think it could be improved by changing tire size. It would likely lower my empty mpg.

10.5 average long haul towing and 19.5 overall average empty. 65 to 70 average mph.

All my touring photos. (except the two massive trips in 2011-soon to be posted eventually)

Will you clarify if you have a tuner or not David....
