I ran the Sailun S637 "16" G Rated tire on my last SOB 5th Wheel for many miles coast to coast.
They were great tires, very heavy, well constructed tires that wore well.
I would have no hesitation purchasing Sailun Trailer Tires again.
Even though they are made in China, I have never heard or read about anybody having issues with them.
