So when you're going a next size wheel, you should go next lower size tire(Aspect Ratio or height)?! Right?
So your wheel+tire diameter is staying the same, so your speed indication didn't change or in other words you don't need update your speed reading ratio(conversion). BTW the speed of rotation would be same at any point of the wheel/tire.
So you're believing , that is bigger wheel will move mass rotation. I don't see how. The change(+_ 3-4 lb) would not significant, to compare to mass of the vehicle itself. Even more, the mass should almost compensating, by less rubber would use with bigger wheels.
He is jsut saying, when buying bigger wheels, if you buy lighter tires, with a slightly smaller diameter instead, the change won't be as drastic.
