I have a similar truck, 2010 F450 with the stock tires 225/70R19.5G. Door sticker says 85 front and 75 rear. Fully loaded (15,000 lbs) my front tires carry 2950 pounds each.

I run at 90 front and 85 rear which gives me a comfortable ride and a margin of about 20-30% below the weight capacity of the tires.
