AFAIK, the same type tire recommendation was a left over of between bias ply and radials from when radials were the new thing.
Run both tires at the maximum rating of the less capable tire. Change out the lesser for a matching higher level tire when you can.

Update: I replaced the other tire too so now have two load range E tires on the Casita.

Weigh your rig and use the weight/inflation chart to determine PROPER inflation and add 5psi to what the chart says.

I have no idea of the weight rating of the trailer, however.... and especially with only one axle I would replace both wit the next size wheel diameter and the next size up tire size and Weight and speed rating...on heavier aluminum wheels, not steel. If you have15 inch rims go to 16s even 17s and D weight rating tire go to at least G rating, as long as they clear the fenders. Ride height increase of 1 inch will not affect anything. Michelin LT tires have long tire life ratings and warranties and uv resistance. I found out what the hot thin air desert sun can do on the right front tire, at 3500 ft last year.... And in 2002 to perhaps 2004 lost all four, not at one time, tires on two axles of a boat trailer. Cheap Goodyear Wranglers at the time, from sun and Armorall.

One axle with two different tire types/load ranges/tread design is a braking safety issues...especially a hard braking event on wet pavement. One tire with the better traction will lock up causing flat spotting... or control loss depending on situations.
Multiaxle trailers have a need for max sidewall pressure (stress from side scrubbing). A single axle has no side scrub issues and no need for max sidewall pressure in this situation.
The trailer came with load C at 50 psi which is a good fit for lightweight trailers. Now 80 psi tires are mounted. I use P tires on single axles for better long term wear and performance.
Using 80 psi can cause the tires to balloon the center of the tread and doesn't allow full tread contact leading to less braking performance. There are reasons for OEM C load tires on light weight vehicles.

If you don't want to weigh the trailer use its GVWR and divide by two. Now find your a tire pressure load chart and use that as a base and fine tune with a chalk mark across the tread. Pull the trailer in a straight line for a couple of blocks. Add or reduce psi for a even wear across the tread.
This is a old method we used when only a few tire dealers had tire load/pressure charts.
