Goodyear Endurance Tire Pressure
Recently, I had 4 E rated Goodyear Endurance tires mounted on my 5th Wheel to replace the less than stellar Castle Rock Chinese tires that were on my camper originally. My EEZ TPMS showed Three tires ...

Yes, the original tires were Load Range D tires.
Recap: You got new tires because you wanted the GY brand. Your original tires were ST225/75R15 LRD. GY Endurance is only manufactured with a LRE in that size. Both the LRD & LRE (any brand in that size) conform to the same load inflation charts. So, no problem, at 65 PSI both will provide 2540# of load capacity. The LRE will provide 2830# of load capacity when inflated to 80 PSI. Your wheels are rated for that load and PSI. Make sure your valve stems are good for 80 PSI or greater. Steel ones would be best.
Usually people purchasing new trailer tires go up a load range to provide a higher percentage of load capacity reserves. Probably all RV trailers with a build date of 2018 or later will have tires that conform to the RVIA recommended minimum load capacity reserves of 10% above vehicle certified GAWRs. Using a ST trailer tire’s full load capacity potential is hardly ever going to damage the tire.
Tire industry standards (USTMA) fully supports the OE tire load capacity with this statement. “Replacement tires MUST provide a load capacity equal to or greater than what the OE tires provided”. So, it’s your option to use any inflation pressure between the minimum acceptable 65 PSI, all the way to the tire sidewall maximum permissible PSI.
