shouldnt they be “closed” laterally for aerodynamics, to block dirt and snow from getting stuck inside? guess these will collect dirt 100 times more than regular tires no?

In another comment it was mentioned that there will doubtlessly be "sidewalls" on actual airless tires, and that the exposed ones shown on this page are just for show. I admit that makes a lot of sense given your point about dirt/rocks entering in and effecting the absorption effect of the honeycomb.

They will have walls, this is just a demo model to show the internals.
