    OK, so the video’s a bit vague on detail. If I ride my semi-flat tyre on a wet road will it get pumped half full of water? I must admit that I am intrigued to see how the non-return valves on the tread surface will work. Once it get’s to the pre-set pressure, does it blow off every few minutes like a truck with air brakes?
    I personally have no problem pumping my tyres with a handpump or a track pump, it’s the only upper body exercise I get 😉

      There is a filter in the pumping mechanism that prevents any moisture from entering the tire.

    Johann: I bet that’s at least … half … false.

    This may be the most fredtastic thing ever invented.

    Right now, the sticking point is that they only think they can make the lumen reasonably wear and puncture resistant. I can’t see how this could possibly last more than a hundred miles of urban commuting.
