Trailer axles??

OK ... IT'S STARTING TO MAKE SENSE TO ME. My dad told me if I got a flat, I could chain it up till I could safely fix it. I haven't had the opportunity to try that out , yet.

I think what MAC meant was that he likes the idea of having the extra tire there in case he gets a flat or a blowout for the immediate safety it provides. I've never had a flat or blowout on a trailer, but I had a GOODYEAR TIRE WITH 7,000 MILES ON IT BLOWOUT ON MY VAN AT 65 MPH, and it was thrilling - but not much fun. I feel a whole lot better knowing I have a spare in place when I tow my cruise missile down the highway.
