Your wheel rating at 3750lbs is odd, I believe, because that puts it somewhere between E-rated and G-rated. I'm assuming, however, that your wheels are adequate for your load. In that case, according to the Sailun chart, your psi could be higher than 80 or 3420lbs, but since your wheel is not rated for 110psi or 4080 lbs, I'm thinking 95psi is the max for those wheels.
