Bridgestone r250. I put them on a heavy boat trailer, replacing 235/80-16 "trailer" tires. Steel sidewalls and HEAVY rib tread. I don't see a downside. Trailer has been on crap Alaska highways, the alcan/cassiar, and all over Vancouver island on pavement and gravel.
The rv forums list r250s, xps rib, and bfg commercial as worthy trailer tires.
I don't buy that "trailer" tires are special in any way, other than that they are cheaply made, lightweight and fragile.
