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
