QUOTE CRAIG......
"I'm intrigued by the fact you think blow outs are minimised since a tubelees tyre deflates slowly. This is exactly what causes a blow out. When your tyre slowly loses pressure when your vehicle is in motion, particularly at speeds of 50mph and over, the tyre heats up and gives the impression of being properly inflated. It eventually reaches the point where it resembles a ripe tomato and any sudden undulation in the road will cause it to blow itself apart."
When the tyre loses pressure a sensor would tell you and you can stop and change the tyre.... The whole point of pressure sensors! Yes the tyre does heat up but this is usually once the side wall is damaged, in the case of a van tyre,Tyre pressure will go up because of heat expansion. A typical racing tyre will go up by 9 or 10 PSI when the temp goes from ambient to 80 degrees C which is operating temp for a racing tyre. The ripe tomato shape is side wall damage and will have happened over a number of miles not instantly, it is this damage which creates heat which will seem to re-inflate the tyre. So a pressure sensor would have prevented you from having one of your vans from laying over to die.......SO yes blow outs occur but they could have been prevented well before they actually happened. Like I said Tyron bands are a sticking plaster and blowouts either instant or otherwise are, for me, never going to happen. I have been working in the racing industry long enough to know the system we use is 100% reliable but to buy would be hugely expensive for consumer use.
