you need a ford scan tool with the appropriate card in it and you enter the revolutions per mile of the tire.
Yeah I did mine also, or should I say atemped, I screwed mine up it was my fault. I didn't enter the right revolutions per mile of the tire. I did that thing where you reverse numbers by accident(dislecsia). Yeah I realized it later. Either way its its close now and was way off before.
