Folks, if you have the newer 2-piece metal stems (rubber base with brass extension) on your trailer, please take a look at my post HERE to see if your stem could possibly cause tire failure or a serious accident.
Bob, unfortunately there seems to be a valve recall every year. Same thing last year, only found out after a major blow out leaving the tire in shreds. But this post is a good reminder that it's one of those things we should check out before every trip.
