I also have Goodyear Endurance ST20575R14D tires on my 3,750 GVWR Jayco. I've been thinking about lowering my tire pressure down from 65 psi. My problem is bouncing, especially on concrete interstates.
If I subtract 12% to account for hitch weight, I'm down to 3,300, which would be 1,650 per tire. Goodyear's Load/Inflation table for these tires shows 45 psi will carry 1,640 lbs. I'm thinking of going down to 50 lbs to see if that helps on rough roads.
For what it's worth, my trailer has a Lippert 3,500 lb single axle. I think these lightweight single axle trailers are prone to bouncing on rough roads.
