My first reaction, is they probably aren't really all that dry, if they were at 55%. I would slowly raise the humidity till you get up to about 65%(by slowly a couple percent at a time over 2-3 weeks). If you bring the humidity up slowly, once you've established an equilibrium of the 65% (stops fluctuating for a couple of days) you should be good to go.
I also would try smoking one as they are and see how they taste, but that's just me.
