We will have to agree to disagree. I believe 50 psi is WAY too much. 50 psi
is the maximum rated pressure, not the recommended pressure. I suspect the
load rating on the tires is about 1500 lbs each. At light loads, 35-40 psi
should be optimal. That should be a good balance between tire heating,
handling, and wear. Try looking at these web sites.

I disagree. Why would you run less pressure? I would run trailer
tires at max or near max rated pressure.
Trailer tires have different sidewall characteristics and you do not
want them acting like car/truck tires.
35-40 on a 50 rated tire is too low, IMO.
Correct me if I'm wrong.
