Question:

looking at ford dually wheels. How is the pilot hole measured? I cant find any reference, from center or other holes where 4.77 or 4.88 inches makes any sense

Pilot diameter on a wheel like our dually trailer wheel part # AM20783 that you referenced is basically the diameter of the center hole of the wheel. This wheel has a pilot diameter of 4.75 inches. I attached a picture that shows this dimension as well. You should note that this is a trailer wheel and it is not designed for a truck.
