Lower to the ground does not always equal better fuel economy.

No. Load carrying capacity has no relation to rolling resistance - except to say that as the load goes up, the rolling resistance goes up. But if you keep the same load (like replacing the tire on a particular vehicle), then as the load carrying capacity goes up, the rolling resistance goes down ever so slightly - all other things being equal.
