Chinese 'Hi-Run' Tires Quality ?

[gowansgary]

I had no choice but to get a set of "Hi-Run" Tires from Bejing, China when my old ones died in a very inconvenient place. I've put 4000 miles on them and they still look OK. Not all Chinese tires can be that bad as there are now 46 million tires made in China in the US ( including the "Primewell's" that came on my used Volvo). My research indicates that some Goodyear Marathon tires were lousy too.
Is there anywhere where I can find unbias tests on Trailer Tires?
Has anyone had a good or bad experience with this brand?
I don't want Chinese tires any more than the next guy, but I don't want to spend another $$$$ for different tires if these will be OK.
I was told that Carlisle brand is the ones I should get when these need to be replaced. Is that so?
Help.
