Tires, what pressure should I use?
Just had a set of Goodyear Endurance tires put on, load range D, same as the originals. GVWR is 2500kg (6700 lbs.), 1045kg (2800 lbs.) per axle, I guess the balance is the kingpins max. Original tires had a max psi of 50 which matches ETI's sticker. Last time I weighed the trailer it was 4600 lbs. with minimal in the tanks.
The Endurance sidewalls say max psi of 65.
Max load Single 975 kg (2150 lbs)
Max load Double 850 kg (1870 lbs)
The tires were from 61-63 psi from the tire dealer.
I put them at 65 psi but have no idea if it is right. Any idea what they should be?

I would keep them at 65 myself. I always have kept all trailer tires at maximum pressure, from 50-80 psi, as recommended by my tire shop manager. Always get good performance.

Bob,
Do you know your pin weight and is the 4600 number axle or total weight?

Dug out the CAT sheets.
Total trailer weight = 4360
Axles = 3840
Pin would be the remainder, 520 lbs.
This was on return from a trip, fridge had been emptied and had about 1/3 in the fresh tank. The other 2 would have been empty, or as close to it as I normally get. I've had the pin up over 700 in the past, depends on the state of the holding tanks.

I bought the Endurance in the spring and have about 8000 km on them. Have been happy with them. Run at 65 lbs

If the original tires had a maximum inflation pressure of 50 psi, they were Load Range C, not Load Range D. No Escape needs the capacity of Load Range D tires, and I've never heard of an Escape coming from the factory with them. Perhaps you meant only the same type and size (ST205/75R15) as the originals.
The Escape sticker says 50 psi because that is the maximum inflation pressure for Load Range C, and they follow the recommendation of some ST tire manufacturers of inflating to maximum allowed pressure. The Endurance sidewalls show the normal maximum inflation pressure for Load Range D.
Since the load on the tires is no higher than it was with the original tires of the same size, I see no reason to increase the inflation pressure unless the originals performed as if they were underinflated. Was there any concern with the original tire inflation?

The pin box can handle far more than that... the lightest-duty convention pin box available is rated for about 16,000 pounds of trailer and at least 3,000 pounds of pin weight.
But it doesn't matter, because if the gross vehicle weight rating is 2500kg, that is only 5500 lbs, and the GAWR is probably 2800 pounds each. The GAWR isn't likely 1045 kg, which is only 2300 pounds, I don't think Escape ever used an axle rating that low on the 5.0TA... although it might have been adequate.
My guess is that the GVWR is 2500 kg (5500 lb), and the GAWR are 2800 lb (1270 kg).
Whatever numbers are incorrect, the original Load Range C tires had much more capacity than required (3640 lb or 1650 kg per axle) so they didn't need 50 psi inflation, and the new Load Range D tires have the same capacity at the same pressure, and even more if pumped up higher.

I recently replaced our marathons on the 21 with Goodyear endurance as marathons are no longer available. I am running them at 62 lbs psi. . During the day in temps have been from 79 to 85 degrees air temp. Tire pressure will rise about two pounds. Running 63 mph on two lane roads, tire temp will go to about 95 degrees, I'm happy at 62 psi. The oracle has spoken.

The oracle has spoken good then I shall lower my pressure from 65 to 62 ⬇️

They do say cold inflation pressure, so must allow for increased operating pressure, which will vary with conditions.

You were certainly duped, Adrian. That was just Dave typing in an eerie voice.

An eerie voice well that's Dave's usual voice is it not? No not duped I really wondered whether I needed max pressure this thread is answering that question

Endurance
I recently returned from towing the Escape 21' from Eastern Iowa to Chilliwack and back on the new Endurance Goodyears I had put purchased to replace the well traveled Marathons the trailer came with nearly four years ago.. I ran the tires at 62 psi cold . I checked them twice during the 4,850 mile trip. At no time were any of them below 60 psi. When I checked them today they were at 60 psi on a 72 F degree garage floor and the air temp in the tire was 72 degrees also according to the TPMS. I liked the way the tires performed on this trip. Braking was excellent, did not have much rain but what we did was no problem. There was no appreciable Squat or Sidewall shimmy that I could detect. I think this is going to be a good tire for Goodyear. Time will tell.
