Thanks so much for the Claudio correction. Two weeks in a row he's said that and had me shouting at the telly! ;)

Opinion: A Cry for Help
"Casings that can’t be torn: Hate to break it to you, but rubber is not armor. Same goes for polyester and nylon. There are a number of fabrics available off the shelf that don’t abrade, and that can stop shattered glass, sharp knives, micro-meteorites, and bullets. Rubber is the heaviest component of a wheel. The only place it should be used is for the tread and to seal the tire. A tubeless tire should never suffer a sidewall tear." To say that fabrics are available that don't abrade is incorrect. All high-performance fabrics will be susceptible to abrasion to a greater or lesser extent which is where the rubber coating comes in on the outside. These high-performance fabrics (Vectran, Aramids, Dyneema etc) are also so expensive that we'd be looking at tyres being significantly more expensive than they already are. This might be fine for racing but for me I don't want to spend £100 per disposable tyre to mitigate against the risk of a side wall slash which happens rarely to me (following a phase experimenting with too-light tyres). In the case of a side wall slash nowadays I'm prepared to fit a tube and sidewall sleeve (toothpaste tube & duct tape) and enter limp-home mode. Also, in terms of density rubber is barely any heavier than any of these high-performance fabrics although they obviously use more rubber.
