I would think 80 psi as rated on the tire.
The sticker on the trailer is for a different tire.Charles and Susan

I put E1 80psi tires on my trailer as well. I fill them to 80 psi because that's the air pressure that the corresponds to the max load rating of the tire.
However, you can get a chart from the manufacturer of the tire that will tell you what load the tire can carry at lesser fill pressures. They are specific to the manufacturer/tire so the sticker on your trailer is of no use to you anymore.
Such as this for example.
