Goodyear Marathons have a mixed history. Some folks have no problems, some have lots. Google "Goodyear Marathon", and you will find lots of stories about tread separation.
I, and a friend of mine who had them on the trailer for his 22 Pathfinder experienced it first hand. Both of us experienced blisters on the sidewalls and tread separation at highway speeds. I had one that the tread peeled completely off and it still held air. We made it to a rest stop about a mile down the road and put on the spare. Between the two of us, we went through about a dozen Goodyear Marathons in a period of two or three years. He lives in Lauderdale, I live in North Florida, so neither of us knew the other was having the same problems until we both showed up at the same place with our boats and compared notes. It was a vicious cycle because they would fail with less than 5000 miles on them and we were both getting them replaced under warranty. We were both running 14" tires on single axle trailers.
I replaced mine with bias ply tires and haven't had a catastrophic tire failure since. Both fenders on the trailer to my SF 20 are pretty beat up from the "marathon" of abuse.
Now, It's possible that I've figured out why my Marathon's were exploding when others have run them without problems. When I switched to bias plys, I got uneven tread wear. Seems my axle spindles were splayed with a little toe out. I'm guessing that the stress that showed up as uneven tread wear in the bias plys was contributing to the more impressive failure of the Marathons. I've since replaced the axle, but I won't own any more Marathons.
I ran Goodyear marathons on the trailer to my flats skiff and never had a problem. They were 13". When I bought the boat, the trailer ate tires like crazy. Same problem with the axle spindles and tread wear. I had already replaced the axle before I put the Marathons on it.
But enough about Marathons. Don and the others are right. I run bias ply tires and replace them every 4 years whether they look bad or not. I'm not sure why you would pay more for radials for a trailer.
