Tire size is obviously a factor. If the tire size is correct, then there is something wrong with the DRAC (digital ratio adapter card). This little device translates the speedo information from the vehicle speed sensor, and it compensates for tire size, gear ratio, etc. and sends the signal out to the speedo.

You'll have to visit your dealer to get one of these ordered, it sounds like perhaps someone changed the DRAC at some point. It's common when people change gear ratio or tire size, and they want to correct the speedo reading. The DRAC is the device that takes all of these things into account, so you'll need to know tire size and gear ratio when you go to your dealer to order one.

I have the correct size tires

Any chance that the axle ratio has been changed from stock? There is also a good possibility that someone installed a junkyard drac into this truck that was programmed for a different vehicle.
