After reading many posts, I think all Chinese tires get lumped together. My trailer came with bias ply Duros and all of them developed sidewall cracks in less than a year from manufacture. The tires were kept properly inflated and covered during off season.
That was my experience, I thoroughly think they would have failed on the road if I had not replaced them. Duro replaced them with like tires which I promptly sold on CL with full disclosure and I put on Denmans before they were made in China and went out of business. No issues in 3 years with them.
While I can't judge all Chinese tires, the Duros sure made me skeptical.
