I wonder how long the linkage between rim and the rubber will be able to take the alignment forces.
As it is airless, how will they handle different terrain? When you drive on sand you want lower pressure, on the other hand lower pressure means higher fuel consumption, so when you don't need the lower pressure, because your driving on roads, you'd fill up the air again.
On the other hand I guess the linkage might provide some additional traction in soft sand, so you wouldn't have to make it too soft.
