Blow out on the truck or the trailer ?? Makes a big difference.
As other have said a actual blow out on a trailer can even be felt let alone cause a truck and trailer to over turn.
Having said that I've had actual blow outs on my trucks and trailers when I was on the road and even with a front tire blowout the combo was easy to get shut down even with a 22k trailer in tow.
Now if your worried about the Westlake tires on the Windjammer you can always sell them on CL or the local news paper add. Lawn service folks are always looking for tire or a set of tires for their trailers.
Then use that money and buy a better quality tire of your choice.
