“Ultimately YOU are always responsible for the tires installed on your vehicle.”
Never assume you can simply substitute the tires shown in a load & inflation chart. Using the wrong size tire - whether too big or too small for your vehicle - can lead to sudden tire failure.
The reference provided is generally very similar to what all of the tire manufacturers are going to say about replacement tires. It’s a tire industry standard.

Your tire installer let you down with your tire selection, in more ways than one. First is the size, it’s not even close to what the vehicle manufacturer had used for original equipment tires and certified on the trailer’s labeling and in its owner’s manual as being an appropriate fitment. A lot of people like to second guess OE tire fitments. That’s OK as long as they use replacements within the safety zone.
Your replacements require a minimum rim width of 6.5”. Your OE rims are most likely 6”. So maybe the installer said they would be OK? Safety is safety, either you do it or violate it.
There were better options for your replacements. They were probably more expensive but better and within existing safety standards.
