To answer your question:
Coming back from Florida last month, I had two blow outs within two weeks.
My trailer is 5000 pounds, and we had probably another thousand pounds in it.
I never felt either one of them.
The first one I was going sixty and the only way I knew it blew was seeing the black shreds flying up when I looked in the mirror.
I drove five miles on the single one on that same side before pulling into our overnight campground where I changed it.
The second one was on I-95 and I was going seventy and heard the pop, but never felt any sway. I stopped as soon as I could and changed it.
Those were the first blow outs I ever had in twenty years of pulling trailers
