I think we are mixing up a number of things here.
The label on the trailer tells you how it was equipped when it left the factory. If you want to change to more capable tires, so much the better. The factory sticker is no barrier to that.
As Padgett has pointed out in another thread, tires labelled Load Range E are only Load Range E if they are inflated to 80 psi. If they are inflated to 65 psi, their load-carrying capacity is still Load Range D. And by the way, LR-D is plenty for a TM.
I run my LR-Ds at 60 psi instead of the max 65 psi. At 65 psi, they are too hard and shake things apart. At 60 psi they still have plenty of load-carrying capacity, but are a bit softer.
The wheels (aka rims) are stamped with a max pressure rating, but in my limited experience, the stamp is on the inside of the wheel - the part you can't see when the tire is mounted. But you need to know this rating before you start putting high-pressure air into them. We have had some forum members who were surprised when their wheels were stamped 50 psi.
