    Just to make sure I am doing this right....I went from 265/65/17 to 265/70/17. Under the speed setting in the scanguage I would change the value from 0 to a +3. Is this correct? If it is, my new Dura-tracs are about 2-3 mpg less than my Yokahama Geolander AT's.

    Okay...since no on answered I figured it out. It should have been +6. However, I discovered with the scanguage you can get it to display the speed from the truck computer and the corrected speed. Using GPS, I had to bump the corrected speed up to +6 to get it to match the GPS. This leads me to believe my speedometer / odometer must be off in my truck.
