Rotating the tires only works with a posi. Otherwise, when you turn one, the other turns the opposite way and the driveshaft just sits there. It is possible if you leave one tire on the ground, rotate the other tire and count driveshaft revolutions. You then either multiply or divide by 2, I forget which, but I think it is multiply to get the ratio. The differential effect of the spider and side gears is the monkey in this mess.
