It's also a good idea to adjust your mirrors so that you can check out the caravan tyres when you look behind you.

That is a good idea..The only problem is US !! If we do not look often enough or carefully enough we could miss the puncture but it costs nothing to do and is a good thing to train yourself to do anyway... As I said the technology needs to be 100% before I trust it without Bands but every thing you can do to stop running on flat tyres and wrecking the tyre is a plus.
Hi,
I have had a blowout on a van but only noticed it because of the sudden increase in noise. We were doing about 60mph at the time and using a spring type stabiliser. The car van ratio was about 80%. What tyrons don't do is to extend the period between tyre changes. Also tyre compounds have additives in to reduce cracking and moisture ingress. However the compounds are only effective when the tyres are used regularly, which most van tyres are not. I use a pre-instaled sealant, and liberally wash the tyres in Armorall twice a year, and store the van on axle stands but with the wheels still in place, so that if she moves the wheels will take the load. The steadies are also down too. And we call this a hobby!

How did you know it was a blow out ???
Radial tyres tend to do down slowly. Over miles. The term blowout refers to an instant relese of pressure. With a pressure sensor equipped wheel set up you might have noticed this puncture 5,10 or 20 miles before your tyre became competely flat!!

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. I've had this happen twice, once resulting in dramatic but safe stop, and once resulting in an updide down position. Incidentally, BMW now say the average motorist has a puncture once every 93000 mls. I'm guessing I've had a few of someone else's.

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.

I'm not saying for a minute that pressures sensors would not prevent a blowout, but not many people, actually I don't know anyone, have this system. The point I picked up on is the fact that a tyre deflating slowly while travelling at speed is exactly what causes tyre failure. I agree that tyrons are a last defense but for most, their only defense. I presume when you say for you a blowout will never happen you mean you use the pressure sensors? By the way, both times I've had a blowout was at sensible speed on tyres with less than 1000mls wear. In the first case the sidewall showed some signs of savaging, in the second there was not enough tyre left to tell. What I would say is no system is 100% reliable.
I have a very different background to 99% of people here so I am coming at the problem from prevention. I have been working with data logging experts and most serious teams who race endurance raceing cars and bikes use pressure sensors, the only time they get problems is when a driver ignores the warning or has to travel to far on a tyre which is not designed for puncture resistance and have been punctured with carbon fibre fragments and de-laminates (this is the most spectacular type you see on TV). The sensor system used on the bikes we race has been 100% over the past 3 years and has stopped some possible serious injuries to the riders we support.
I have had some parts used by the teams and built a system for my own use and to buy this one would be too expensive (possibly
Sorry for a repost... I just want this in the main section.....

In the United States, FMVSS 138 requires tyre pressure monitors to be fitted on all vehicles built since 2003 so it's only a matter of time before a similar regulation or industry commitment finds its way over here to Europe.
Personally I think it is a good idea. It will almost totally stop incidents where a flat or blown tyre causes injury or damage.
Here is a link to the type of product we use.. We log each tyre indevidually in real time use sensor alarms to alert both the driver and pit wall as soon as possible.
