Brazilton KS | Are you sure you have read all the appendices of the load charts? "Free rolling" is worth a bunch. "Cyclical loading" is worth a bunch. low speeds are worth a bunch. The weight that is not on the tires doesn't count, of course. The bottom of the Firestone load chart adds 85% for cyclic loading, low torque, and 10 mph maximum, with 5% increase in inflation. That takes a 73-44-32 16pr to 28,000 lbs per tire.
