For tandem trailers having two or three axles, Rich Luhr's "Newbies Guide To Airstreaming" actually says that for short distances, you can simply remove the flat tire and drive without it. He says that Airstream says up to 100 miles!
Of course, that will stress the other 3+ tires and you must reduce speed to 30 MPH or less, but it would get you to where you can get help.
I wouldn't want to try it, but it is an option. As I wrote elsewhere yesterday, I plan to get a new set of five tires asap for the used tandem trailer I just bought.
I've also heard that a blown tire can cause a lot of damage to the body of a trailer, particularly an aluminum one.
