Never heard of them except as OEM tires on Forest River's brands of trailers. If you have a tire, look at the DOT number and the manufacturer code (first two digits, which will be letters), and then look them up in the DOT database at https://vpic.nhtsa.dot.gov/mid/
I suspect you will find a Chinese manufacturer consortium (representing several factories). It's common to market tires from several different factories under a "brand x" private label. I think a company called Lionshead distributes them, and they are sold direct to OEMs and thru online outlets such a etrailer.com and Eastern Marine. Good luck on getting a warranty adjustment.
