I think some of the tire inflation, disagreement, is due to talking about many different types of tire use. What works for cars, trucks, DRW trucks, motorhomes, and trailers, is not comparing apples to apples.
Most put the proper tires on their tow vehicle, and adjust as needed for load. I see some people buying way more tire than their trailer needs, then reducing pressure, way below max, when they should have just purchased the proper tire needed for the load, and aired for the load.

I agree. My old Komfort, with 11,360 GVW, was placarded for D tires. At about 2550 lbs per tire, that put the tires UNDER the GVW; the rest is carried by the truck. Fine for most, but too close to the limit for me and, after I lost a tire in the 2nd year and another failure in the 4th year on the 2nd set of D's, I went to E's and ran 70-75 psi almost exclusively for the next 9 years and 2 sets. There were a couple occasions that I was running heavier than normal (extra ice, food and water) and I'd inflate to the full 80 psi. Using my temp "gun", the E's at 75 ran at least 5 degrees cooler than the D's ever did, and they were always inflated to 65 psi.
My current KZ, 860 lbs gross lighter at 10.5k, had D's and I replaced the original tires with a set of Endurance D's. So far, they're working well. I'd've gone with Carlisles to save some money, but Discount didn't have any and had none in their entire national inventory at that time. I was time-critical in that we had a camping trip planned and I only found the bad OEM tires (2) about 3 days before leaving.
