These are the two options I have locally to replace my 12 year old trailer tires and trying to find out if they are any good. If it matters my tire are 155 80 13s. 

I have no experience with Uniroyal "trailer" tires, but I do with their car tires. Several years ago I bought a set of Uniroyal tires for my wife's Thunderbird. After six months or so, the steel belts in two of the tires broke! I took the car back to the tire store and they replaced the tires. After a few more months, the belts broke on one of the new tires. This time neither the tire store nor Uniroyal would stand behind the tires. I'll never buy Uniroyal again. As a side note, neither of us have ever had manufacturer tire failure before or after. 

I would go with the Kumho's or the tire that replaced the Goodyear Marathons, can't recall the name.

Just wait and order Goodyear Endurance tires from Tire Rack and have them installed locally.

12 year old trailer tires.  Yikes.  
 

i tend to replace my trailer tires about every three years or so. I get whatever Load King or Trailer Master tires Walmart has pre-installed on wheels at the store.  Price ends up being about what a set of tires mounted and balanced would be separate.

Best trailer tires made imho. Not sure if you can get them in 13” size.

Thanks everyone I went with the Kumho tires and unfortunately due to an older odd size tire the two I listed were the only ones available. The Goodyear’s would be for my bigger boat, that is if I ever purchase one.
