ST tires made in china doesn't equate to junk tires just like ST tires made in the usa are a quality tire. The commercial grade all steel ply carcass 16" Sailun S637 load G is the holy grail for regional service haulers and rv folks pulling 14k + lb rv trailers.
Hell at one time all ST tires were all made in the USA by our top domestic tire mfg....and they were still krapz tires for road trailers.
Once any brand ST tire hits the streets under a rv trailer or trailers used in commerce it going to take 3-5 years before we can say their still a krapz tire or they can compete with a ST tire like the Sailuns or the Providers.
Time and miles of service will tell us if Triangle has a quality tire or just another old style ST class tire.
