I would assume that eventually the pump tube breaks open as you use your breaks.
Yes, but does the pressure keep going up until the tyre explodes?
No, it stops when it’s full, according to the video.
In the video he mentions that the pressure quits building after a certain point.
The video shows him stopping after a certain point, it does not show the pressure stop building as he continues riding. Perhaps it is still in development. The concept is quite nice, but what happens when, as Stephen surmises, the tread wears down and the pump tube wears out? does the tire begin to leak air? Obviously you will need to replace it but how soon after the pumping mechanism is rendered inoperable, and how long will it take to wear that down? It seems to me that, self pumping or no, this tire will have the same, if not shorter, operation length as a regular bike tire.
