With 5 trailers on the road and 28 tires on the ground I went to a better class of 14"/15"/16" tires. No more trailer tires.
The only trailer tire I'm aware of that has 8-9 years of very good service in the commercial side is the Provider from Taskmaster in the sizes I mentioned.
Tires like Goodyear endurance...Carlisle HD have been on the market for just under two years. Time and 25k-35k miles of trouble free service will tell the story.
Now if your trailer needs a 16" load G tires then the Sailun S637 all steel ply carcass is tops.
