Patriot,
I agree that 100 lbs isn't a significant change in weight. But it is more than just the weight. You have the angular velocity, angular acceleration, and angular momentum (torque) of that mass spinning, accelerating, and decelerating every time you change vehicle speed. There is a lot of energy loss there in changes of the moment of inertia. There is also a rolling resistance from the deformation of the rubber in the tire that may or not be different between the Nitto and the Duratracs. Give us a read on the actual mileage change after you run them a while. Great experiment.
