I'd be worried about the weight when it goes through mud.

re: stiffness, I thought that too then I thought about it and reckon an air filled tyre would look like that too ... perhaps.
tuning is probably done by drilling holes in the side walls!!
and as for filling with mud, dust, stones etc, I an sure thin flexible sidewalls to cover the holes would sort that out.
I wonder if there is a problem with the metarial tiring so over time they get softer until they collapse ..... but if it can be made to work, it would be really super - no more punctures = not carrying puncture repait kit, tyre levers, spare inner tube(s) and pump!!

Here is what pneumatic tyre looks like: http://www.youtube.com/watch?v=hiiPiNX90tw" onclick="window.open(this.href);return false;
On the other side if you check the airless tyre clip starting around 2:08, you will see that tyre doesn't conform to the ground at all and gets deflected off every tiny stone.
