80 PSI on Aluminum Wheels
I'm running 225/75/15 D rated tires on aluminum rims inflated to 65 psi. The only GY Endurance tires I find this size are E rated inflated to 80 psi. I do not know anything about these rims other than...

"According to Endurance owners the tire is stamped on the sidewall "inflate to xx psi"."
I bought a set this summer for my tandem axle boat trailer. I weighed the trailer and run 55psi instead of the 65 on sidewall. I will have to investigate further but I am fairly certain it says "MAX inflation 65psi".

In fact what is imprinted on the sidewall of a Goodyear Endurance tire is - "FOR MAX LOAD INFLATE TO XX PSI". In the case of my ST205/75 R14 Endurance that XX would be 65 p.s.i. which is how I run mine on wheels which previously wore off shore shoes in a C load range rated for 50 p.s.i. Some new Endurance owners seem to want to run less than full rated pressure but I wouldn't be one of them - mine run great at their maximum rated 65 p.s.i.

Please explain WHY you run full psi when your load may only require 55psi?
How 'bout - because I can. :W
The trailer tows better than it ever has before and contrary to opinion from those who've never owned a set it doesn't tow harshly at all when inflated to their maximum rated pressure, in my case 65 p.s.i. Best tires I've ever owned and in a few years I'll hope to also report no issues, unlike the stock, off shore, soft sidewall LR C tires, one of which self destructed ... just because it could. :W JMO, but as this all relates to the OP I see no reason to not run these tires at their maximum rated pressure as long as the rims on which they're mounted are also rated for that pressure.
