Bought these to give a US company a fair shot. After 20K miles I had to replace two that developed a bulge rendering them unsafe. The remaining two I'll likely have to replace in the spring as they are very noisy.
About 1/2 the way down to the tread bar so certainly this was not a good buy for me. The dealer I talked with about them indicated they had quit selling Coopers due to problems and awful customer service so I didn't even attempt to pursue any warranty claim.
I won't be buying Cooper again. The are definitely the worst tires I've ever owned. Driving wise they were fine initially but for longevity they are a complete failure.
