Tireman9, didn't see your post, but appears FE gave you the information you asked about...I saw it on the Sailun Tire site also. I was impressed with the Quality certifications that they had passed. My company has to meet the same certifications, which we do, to remain a Tier 1 Automotive Suppliers status, and I KNOW it takes a lot of work and very good record keeping (ie, training records being just one facet of the process), to attain these certifications. Thus the reason I was a little more impressed with these "made in China" tires than any others that I'm familliar with. Appears the Sailun tires do have very good quality processes in place and meet them, or the wouldn't get these certifications....
