You didn't mention the model year of your truck. If it's pre-99, there's a procedure to do exactly what you're asking. I don't know whether you can do it on Superduties or not.
What model year is your truck?

Use the search function for the forum. There has to be a least a dozen posts on how to do it. It's based on the year vehicle you have, but all the explinations are pretty straight forward. When you get to the point were your suppose to measure the wheel circumfrence, measure it three times by rolling the truck, and make sure you have the tires warm before you do it.
