I wouldnt for a moment want anyone to misread my diligence to dodge debris as flat prevention but it is where it all starts. In my thread about weird flats earlier this year I opened with an example of my kind of weird....a tiny, barely visible piece of wire that could only be found with feeling. It was a wire of radial tire belts on the roadside. I had made it home before it went flat and here was this puny wire in the sidewall.
