Trailer service is the most severe service a tire can be put through. Trailer tires are drug sideways around sharp turns, so they have to be made stronger than ordinary LT tires. Most LT tires are not rated for trailer service, so you shouldn't use them on a trailer. There are a very few LT tires that are rated for "all position" service, which includes trailer service. For example, Michelin XPS is one of those LT tires rated for all position service. But the popular Michelin LTX is not
rated for all position or trailer service. So if I needed a 16" tire that is available in the XPS tires, I would put those on my trailer. But not the LTX.
For years, Cooper made the ST Custom Trailer Plus tires, and they were outstanding. But Cooper stopped production of their ST tires a few years ago, so I had to look for replacements. I've been very happy with Maxxis trailer tires so far, but they have limited sizes. I need ST205/75R14E or ST215/75R14D for my TT, and Maxxis doesn't make that size. Here are the sizes Maxxis makes in their ST tires:

The reason a lot of folks have trailer tire problems is the tires aren't rated for enough weight capacity for the wet and loaded trailer. If you can get 25% excess weight capacity over and above the GAWR of the trailer, and provided you keep the tires properly inflated for the load on the tires and don't overload the trailer, then you probably won't have trailer tire problems. Two of my trailers have Maxxis 225/75R15E tires that replaced 205/75R15C, and I haven't had even a flat on those Maxxis tires for several years, or on the Cooper ST tires before Cooper stopped selling ST tires. I just finished a 4,500-mile round trip with my cargo trailer that has several-year-old Maxxis ST225/75R15E tires without any tire problems.
