I saw a Semi load of furniture burn to the trailer frame.
Because there was a flat tire on his back duels,he either didn't know he had.
Or if he knew but kept driving til it ignited,& caught the trailer floor on fire.
We all know burning rubber is one of the hardest fires to put out.
However not knowing you have a flat,is a lot different then brakes hanging up.
I know I could feel the drag in the winter months when my brakes were frozen going out on my route.
