They need to be replaced, and the local tire stores seem to be having
an issue identifying the correct replacement. A brief web search has
also been unsuccessful.

Any advice on the correct replacement, or where to find the code for
reading the markings would be appreciated.

I'm using Yokohama 185R-14 steel belted radial light truck tires. The
model is Y356. I drive too fast for ST tires and these have worked
well for 3 years.
Discount tire sells them for about $100/ea.

Try tirerack.com - they have Kumho trailer tires that match what you
have. I've used their semi trailer tires and found them to be
acceptable, but I don't have any experience with the smaller ones.
They list them for $ 80.00 each plus shipping.

I'm in this game too -- trip to Uvalde coming up, cracks in the
sidewalls. Warning for others: two tire stores in a row have refused
to put car tires on a trailer, and there is no such thing as a 185 70
R 13 trailer tire. Tirerack.com and local gas station here we come.

Note Cobra also has a new maintenance sheet on their website
emphasizing adjusting the brakes, inspecting the hub, and inspecting
the brakes and replacing the shoes occasionally. John Murray
encourages me to do this. Boy, it's going to be a fun weekend, but
better than a blowout halfway to Uvalde.

But there is a 175/80 13 trailer tire. Slightly bigger diameter, but
that gets the back of the trailer a little higher, so you don't drag as
often.

I suspect that many of the failures involve heat build up due to low
inflation. A slow leak will do it.

It's a good idea to use an infrared spot thermometer to "shoot" the tire
tread and bearing hubs at each stop. Do it on the tow vehicle tires too.
This may well provide advance notice of a slow leak or overheating bearings.
They are available from about $10 (Harbor Freight and with a 1/1 spot) on
up - - much more expensive when the heat range goes beyond 1000 degrees or
so.

For road tires, you should be seeing 200 F, so a high heat range meter
isn't all that important.

When checking tire temperatures, expect to see higher temperatures on the
leeward side, the sun lit side, or the lower side of a cambered road. With
even inflation, usually the spread won't exceed 30 to 40 F (but I seldom
drive over 60 mph so YMMV).
