Auxetic tires.
« on: May 29, 2015, 08:50:00 pm »
The main problem with bicycle tires is they stretch when inflated. This pulls the rubber apart when it is cut and allows glass to cut deeper.  There are ways to solve this problem by introducing particles into the rubber that are in compression. Gorilla glass works this way. However as usual nature has come up with something better. Auxetic materials get fatter when stretched or thinner when compressed. Use of these materials in a tire would introduce a compression force at the point of a puncture preventing further cutting. Don't hold your breath. I'm still waiting for spiralock threads for bicycles. The bicycle industry is around 100 years behind the automobile industry.
