Schwalbe Procore in Plus Tires?

Here is my initial video showing the Procore system setup in a plus tire.
It performed well at first and seemed like it could be the ultimate setup for running ultra low pressures on a tubeless tire without the risk of burping or rim strikes.

Here is the video showing why I am no longer using this system.

I don’t think that the system would perform any differently in non plus tires, since it appeared to be related to the double chamber valve stem, but I would love to know if others have experienced the same problem. Let me know below in the comments or via email: RideAlongside@gmail.com

Thanks for watching.
