Go with Michelin XPS RIBs in 16". You will need new rims, and 6 lug drums to make it work. (That TT started out with 14" tires as well)
This was my solution in 2006 to constant tire failures. It was expensive, but worth it as I have never had another problem
Aside from this being almost 2022 and not 2006 when my boat trailers were spitting out 14" GY Marathons like Chiclets at a hockey game, your "sage advice" is not only very costly, but may likely require lifting the trailer suspension.
I can't think of a great reason to go through this for a single popped tire.....or even a marginal reason to do this on a basically new trailer, that, loaded to it's max gvw will have 16-1700lbs on each tire.
30% + factor of safety based on worst case scenario seems like more than enough. 100% factor of safety as you're proposing is the definition of overkill when I just looked it up in the dictionary!
Edit: I forgot, OP never even confirmed or even posted his suspicion as to the cause of the blowout. Yet you're recommending upgrading the entire undercarriage to what is under my trailer with a 13klb gvw.
Why not just recommend tandem duals, you know, for "safety?"
