It makes me wonder if Lionshead is financially stable. Normally, on a recall, you do your utmost to get the tires off the market as quick as possible. I've never even heard of a cutoff date being implemented.
I might advise calling your trailer dealer, or Forest River.
BTW, we try to keep a list of recalled tires stickied here:
