What should the PSI be in the trailer?
I have a trailer which has Sailun G rated tires. The maximum PSI of air is listed as 110 PSI. I was carrying 90 PSI but recently was told that the maximum PSI, that is 110 PSI is the amount of air I ...

The issue with all this dialing in and weighing is that it does not give you any added margin. I don't want my tires to be exactly at their capacity. I want a bit of additional capacity or safety margin.
When I hit a run of pot holes and rough roads I want my tires to be able to withstand the additional impact.
My G rated Sailun's are up to the challenge. Aired to 110 PSI I have lots of margin to withstand the rough roads. MY E rated OEM tires were not up to the challenge and I ended up with blowouts forcing me to seek a better tire.
G rated Sailun's aired up to 110 have resolved all my tire issues.
No charts or individual wheel weights required.
I had the same issue with my prior RV. The D rated tires were not up to the challenge, but E rated tires aired to the max resolved my blowouts issues once again.
In the end you can weigh and air to match some mystical chart if you like but I will go with the max. PSI method.
I am referring to RV trailers only. Most other trailers have totally different characteristics and aerodynamics, the max. pressure method may not apply
Do you run your 4 rear truck tires at their MAX 80psi?
I have at times run 80 psi on my last truck. Had a flat on my passenger outside dual wheel. I was glad I had my tires aired up.
I do agree I don't need to air the rears to max. But max air does not appear to hurt anything. Ride maybe a bit rougher, but the extra pressure did not effect wear. As mentioned in another thread I got 80K on 3 sets of Michellins.
