Tubeless and airless? There's hope

I’d like to see this implemented in MTB tires, with special care place on grip and stiffness. I’m sure they could have different versions of “sponginess” or something. I know there are things you can shove in your tires now, but those are largely crap.

I would have a lot of questions. A car is a car… on a bike, each rider is different… Rider weight would play a role… terrain… how easy to mount… sidewall… lots of variables…hmmmm Interesting concept
