Crasher, this will be my last post on this thread. We actually are both off-topic here. The OP asked about two specific brands of tires from Chinese manufacturers. Unless he asks for advice on other brands than the two he's considering, we're both doing him a disservice by harping on our own theories of what we think about RV tires.
That said, I'll make one last rebuttal to your assertion and then I'll go away.
Your friend had a blowout with a Hankook tire. So the conclusion is that Hankook makes a bad tire. He should should have put Michelins on his RV and then he'd never have the bad luck he is having and would once again love RVing.
The problem is that even Michelins can have blowouts. I had one myself with my Michelin XRV OEMs. Most times, it's the fault of the owner ...not monitoring proper pressure or overloading weight, etc. However, there's also just a bad tire to begin with. Yes, Michelin does have the occasional and not so occasional bad tire. Putting Michelins on your motorhome does not guarantee that you won't have a blowout. Look at all the problems with sidewall cracking and zipper blowouts that Michelin had several years ago. Many won't buy Michelins again because of that fiasco. There are dozens of threads on this forum as well as other RV forums of problems with Michelins.
I could say that Michelin will never fail and Hankook, Toyo, Sumitomo, etc. will always fail because they are inferior products. But I don't believe that. You do. So we can continue to go around and around on this forever. I'm not going to change your mind nor will you change mine. But I'll defer to you:
Michelins will never fail. Hankook, Toyo, Sumitomo, Yokohama, Samson, Sailun, etc. etc. are crap, will always fail, and give you continuing problems. Spend the extra on Michelins and you'll never have to worry about a blowout or tire failure and your RV enjoyment will always be a happy and positive one.
