There is no way I would use one of these kits except as a get you home device much like a space saver. Having spent 10 years as a roads policing officer I have seen the results of tyre failure on A roads and Motorways. If I get a puncture I get a new tyre, my life and others depend on that little patch of rubber. Incidentally the Police never repair tyres always replace.
