Your '17 Bighorn 39MB shows to have a 16000 gvwr with tandem 7k axles.
Sailun S637 is a all steel ply carcass commercial class tire. The ST235/80-16 G has 4080 lb capacity would be a great tire with plenty of reserve capacity on 7k trailer axles.
The Sailun S637 has been around since the '10-'11 era on commercial class regional service trucks and trailers as a LT tire. Later Sailun changed the tire LT designation to a ST to get around high tariff rates on P and LT class tires.
Their becoming the holy grail in the rv world for rv heavy trailers with 7k and 8k axles.
I have six S637 on a GN triaxle trailer since '12 when they carried a LT designation. With over 32k miles they should last as long as I'll be around pulling anything.
