I had a trailer tire explode almost as bad as yours, damn thing let go under a bridge.
I thought someone was shooting at me.
Everytime I hook up I don't move my trailer without checking the air pressure. Takes 2 minutes, a hell of a lot less time than changing a tire on the side of the road.
Don't forget to grease your axle bearings. Trying to match up bearings in podunk on a Sunday evening can get pretty interesting.
This kind of stuff is pretty easy to remember after you've been through it once.
