Beef ribs wow

[IcedGotti]

So I tried my hand at beef ribs tonight.  I used my standard rub and added a little brown sugar to the ends of the ribs.  They tasted amazing however they where not as fall off the bone as the pig ones are that I make.  Is this normal or should they have rode a little longer.  Everything I saw told me they where done but not the tenderness I expected.  Smoker stayed 225 the whole time also so not much temp change per PID.

I had the same experience when I made them once and I wrapped them back up in foil with a little apple juice and cooked them for another 4 hours and they were very tender then.  So, my recommendation is to cook them for a little longer.
