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...

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?
I do it for the additional margin or extra capacity. The tire is only as strong as the air it contains. I want the full load carrying capacity of the tire even if I don't need it.
When my rig is banging into potholes on I-81 I want the trir to be as sturdy as possible.
I have had to blow outs caused by potholes. However moving to a heavier maximum inflated tire has resolved my issues inflated.
I'm less concerned about wear and longevity than I am about a total failure due to impact. I want zero flex.
