Your #1 point is just another example of why not to "roll" with the typical OEM chinese brand. Recent trends toward a quality constructed tire include models from Carlisle, Goodyear, and Maxxis. I'm surprised you pushed the proverbial 'envelope' with the Trailer Kings after being a member on here for nearly 3 years.

Remember too, after a tire failure, the other 3 tires will have been compromised even more and will likely have the same fate if they continue to be used (this includes the spare).

Personally, I would make it a priority to replace all 5 tires before any future travels with one of the forementioned brands. If your wheels support a bump up in load range, even better. Good luck.
