Technically an owner is not violating the trailer manufacturers recommendations by using a replacement tire of the same designated size with a higher load capacity.
Here is one with a lot of load ranges. ST235/80R16 is a designated size. It provides a standardized load capacity for each load range. They are calculated at 5 PSI increments thru the whole set of load ranges from LRD to LRG. Therefore, the vehicle certification label is not compromised if it has that tire size designation..
If your OE wheels and their valve stems are rated for the higher PSI ratings necessary to take advantage of the increased reserve load capacities of a higher load ranged tire, go for it. You cannot overload the wheel without overloading the axle.
But, there is such a thing as "over kill". IMO, that's anything that provides load capacity reserves of more than 20%.
(Vehicle manufacturers do not mention brands on vehicle certification requirements. Maybe in a sales pitch or brochure but not on certification. Theoretically, the tire size designation on the certification label can be satisfied with any brand with the same size designation).
