What is the Front Axle Capacity (GAWR-Front) of your Ford Chassis? I'm not a betting man, but I'd bid high that it's 5000-lb. At 75, your tire size supports 2560 Single. 4620 total, safe for a full load of 5000.
Now, what's the Rear Axle Capacity (GAWR-Rear)? I'll bid that it's 4300 (dual at 62-psi) time two, or 8600 GAWR-Rear.
All Thor is doing is reiterating Ford's recommendation for a MAX-loaded copy of your chassis. Which is loaded lighter. Adjust pressure to actual load as noted above.
And Desert Captain is SO RIGHT. Beyond wildest imagination. Just had all new tires installed, and the shop "sidewalled" them. 80-psi all around. In contradiction to written pressures I'd given them, based on load. Up on a high bridge, in crosswinds, we almost lost it. Just about couldn't keep it on the road. Stopped right after. Sure enough, 80-psi front. Dropped them to 65-psi. That's per the weight chart and we have 4600 on the front axle, way more than you do. The controllable drive returned with the 65.
We've told you how this works and why. You pays your money and you takes your choice.
