So 40,000 pound GCWR on E rated tires?

UH.......don't think all 40K will be siting on the 6 tires. I tow 33K combined and my rear tires are inflated to 65 with reserve at that psi. Fronts are at 80 but little extra weight would be added if any since a 40K combined would be with a gooseneck hitch at 15 percent pin at 6K. My pin is 5,800#.
