Aluminum rims. I am going to take the spare in and check to see if a pressure is listed before I order tires

You are basing your statement on what engineering or wheel design knowledge.

Based on your statement you are claiming a 15x6 passenger rim rated at 45 psi would be OK to use with a 100 psi trailer tire.

Definitely NOT SAFE

I agree, and for an example....
I purchased three 15x6 x 5 on 4.5 rims last year. Two aluminum for the axles, and one steel for the spare.
The aluminum rims were noted on the site I purchased them from as 2150 lbs and when received they were clearly marked with the same load rating. However, there was no max psi noted on the site, so I contacted the manufacturer and they stated 80 psi max. When received, they were not marked for max psi, or at least I could not find a marking.

The steel rim was noted on the site and clearly marked on the rim as having a max load of 2600 lbs with a max psi of 60.

So, it is clear that all 15" rims are not equal in psi or load ratings.

And it is not just the differences between steel and aluminum.

Dexter makes many steel rims; for two examples in the same size; one is marked for 1820 @ 50 psi max, another is marked at 1820 @80 psi.
