Haven't had a blow-out, but did have a tread separation that took out the fender, bent the steps and damaged some underbelly stuff. Insurance took care of it without question and no hesitation. After replacing the tires, we continued to have tire wear issues on one tire. At the advice of our RV tech guy, we had it aligned and that was part of the problem. We then upgraded from D load range tires to F. A G load range wouldn't fit our rig. Since that we have had ZERO problems and this has been 4 years, when with the last set of D range tires, we continually had problems every year. If you have ever read Roger Marble's RV tire articles on his blog -
rvtiresafety.net, Chinese made is not the issues - over weight, improper care - including driving over the recommended speed, alignment, etc. are the issues. Note - I sent Roger pictures of our tires and the damage and from that he made the tire separation diagnosis. He's a great guy and great resource to have. Take his advice.
