Although made by Cooper, I believe they are still manufactured in China in Cooper's plant in Rongcheng City. They have a pretty good reputation for a "third tier" tire by the trucking industry. Many of the Chinese made tires are getting better and have increased their reputation amonst truckers in recent years and many RVers are using them with good results too. If you are thinking about buying them and are getting a good price from your tire dealer, I think you'll be just fine.
(With that said, for me personally --at this point-- I still prefer tires from the Japanese and South Korean manufactures like Toyo, Yokohoma, Sumitomo, Hankook, Kumho, etc.)
