The benefit of the E tire comes at those higher pressures...
I don't accept that. It is only true if you are looking for the added load capacity.
Since the LRD tire handles the load, the benefit of an LRE is the safety margin of running well below the tire capacity. The heavier carcass that gives the tire an 80PSI capacity, also increases the tires resistance to bruising and belt damage. Putting more rubber and belts between your trailer and various road hazards is a benefit.
Running the LRE at 65 or 80psi, or anywhere in between is a choice, and may affect running temp, tread wear, and ride. Those can be debated. But it is a better tire either way. Personally I run them at about 70-75, because I like to be a bit below the max rating, and I don't really need the full load rating.
I find no difference in ride quality. Not sure how I would notice that, since no one is riding back there, but things don't move around the trailer any more so than with the OEM LRD.
Cost is the only legitimate reason to stay with LRD, which was the trailer manufacturers prime directive as always. But the extra cost for LRE is so minimal, going with LRD would be penny wise and pound foolish in my opinion. Wheel rating notwithstanding.
