Any steel ply tire is going to do a lot of damage if it fails. It is a balance between having GY repair you trailer under a warranty that does NOT include consequential damages out of goodness of heart or a tire that has been noted to have hardly any failures. A trailer that gets 4-6K in damage will never be like new again, so pick your poison carefully. In the past is has been G614's used near their max rates that had most of the failures.
After the fact is not always clear how the failure occurred. Many that claim a blow out may have actually been road hazards that damage the tire causing the failure.
None of this applies to Blow Max's, as they are truly china bombs like a lot of other poly carcass ST tires.
