Wow, I have never seen that before, I went with the new Goodyears that are made in the US, they seem to be good tires but time will tell. I also went from C to D rating, the gvw rating on the trailer was more than the tires were rated for and I figured that as that trailer moves over bumps it moves weight from the tongue to the tires and back.

I just put the Goodride 225 75 15 E rated tires on, 9000 klm at 100 100 klm per hour most of the trip, rated for 75 miles per hour, and trailer was over 8000 lbs, tires still look awesome, towed good, ran them at 80 pounds. traiiler was over 8000 lbs
Will see how they are in the long run.

ST's are an economical solution to be able to get a tire that can handle a given load but without the cost of LT's... almost all of them are rated for a max of 65MPH and most of your stock STs on a trailer only barely cover the gross vehicle weight.
now slowing down when towing isn't a bad idea and you shouldn't be exceeding your gross, but the point is, most people are running them at their max ratings for both speed and load and most people don't tend to wear out the tread as fast so people tend to drive on them with greater age on them as well.
the only down side to LT's is finding a size that will work and the increased cost... everything else is a benefit.

Your fifteen year old tires cracked. I'd call that a win. If you like how they ride, Consider sticking with those and get some tire covers. They're still under $100 each in the US.

The Goodyear Marathons with white letters were made in the states. The blackwalls are made in China and have been a disaster. Issues are across the board on all kinds of trailers. This is a common discussion on the Bass Boat boards I am on and that crowd is RELIGIOUS about checking tire pressure. I ran my white letter marathons on my boat for 10 years and had a bubble form under the tread, but it never lost pressure. I did not want to go with "China Bombs", and I put Kumho 857's on and they have been good. They are now 4 years old, and my spare (original Marathon) now has a bubble under the tread and I'm thinking about going to Maxxis all around.

What is the cost of re tire'ing your trailer? Even every year? Wouldn't that be cheap insurance?

Some heavier duty trailers like my GN Horse trailer come from the factory with LT tires. Mine shipped from Sooner with LT235/85/16E. They have worked well and I replaced them with the same size Hercules Terra Trac IIs, they are 3 years old this year, and look great. I park on several inches of gravel that drains well and so far no weather checking at all and the seem to ride very smoothly on my trailer, much better than the GY wranglers from before.

As for trailer gross weight, dunno, four trailer tires rated at 3,000lb + each far exceeds the gross weight of most TT's and 10+% of the weight is on the truck when towing.
