  1. Fitting Tyron bands is a bit like selling fridges to an eskimo. Whether emergency services fit them or not, they would invalidate the warranty on private cars, because no car manufacturer would approve of an item which increases the wheel unsprung weight and its moment of inertia without intensive testing and, to my knowledge, no car manufacturer has ever got involved with Tyron bands. If emergency services do it, then they do so at their their own risk.
  2. Sounds all OK to me. Just put as much as you can in the car.
  3. Even the tread can do a fair amount of damage, never mind the bead. Also, even if the bead stays on the rim, that's no guarantee that the wheel rim won't get damaged, too.
  4. If the tread was 100% lost and the sidewalls were 20% gone then the tyre no longer had any lateral grip and it was immaterial whether the remains stayed on the rims or not, whether with or without Tyron bands. For what it's worth, chances are that the tyre beads would have stayed on the wheel rim even without them.
  5. I've always very quickly been made aware of a blowout. First of all, there was an almighty bang, followed by bits of rubber flying through the air, as seen through the rear view mirror.
  6. The wheel is still there, though, even if the tyre has gone. So long as you're going in a more or less straight line, the wheel will still do it's job. Only if you have a blowout while negotiating a bend can the lack of lateral grip of the wheel become a problem.

    Loading Tow Car

    Even if it were 300kg it would still have been unrealistic. When my car is fully laden, the payload alone is already a substantial chunk of the 300kg per wheel.
  8. All I can say is that I've experienced a couple of blowouts, both on the car and on the caravan and although it was a shock when it happened, I never had a feeling that this is the end. I wouldn't wish anyone to experience a blowout, but on the other hand I think the horrors of having one are grossly exaggerated. Besides, the whole concept of Tyron bands doesn't impress me because they can't, simply by virtue of their design, prevent a tyre from disintegrating as they have no means of restraining the tread, only the tyre bead, so I don't understand what benefit they can be.

    It's rare for a fully laden car to be noticeably heavier at the front than at the rear. Certainly nothing like the example that you cite. My own car has a max. front axle load of 1300kg and 1350kg at the rear. Having said that, the situation that everyone is looking at first before talking about caravans flipping over is the case of the 'tail wagging the dog' and that's the reason for the 85% (or whatever) weight ratio recommendation. This weight ratio has nothing to do with the car preventing the caravan from overturning, but to prevent the caravan slewing the car off course. That's going to happen long before the caravan is likely to flip over.
  10. As thefts are not an issue here, I don't bother to insure the caravan while it's in storage, so I can't say. I only insure the caravan while it's actually being used on the road.
  11. Assuming you are correct and all have Tyron bands as standard, then the video in youtube of a South Yorkshire police patrol car having a blowout and then going into a spin doesn't do much to instil confidence in their performance.
  12. Same applies here in Germany. While the caravan is in storage I only lock the door and that's it. No hitchlock, no alarm, no wheel clamp. Even the storage area is readily accessible to anyone with a minimum of determination.
  13. Funny you should mention that. I was parked with my Dethleffs on a city car park in Peterborough last year when a scruffy Ford Transit pulled up next to me and the person inside called out: "Arrr, tis a verry foin caravan uve got there, t'be shurrr". Fortunately, I was parked with the caravan only inches away from a wall at the back and my car blocking the way out front
  14. The video doesn't show how the Range Rover would have behaved under the same conditions if Tyron bands weren't fitted. That's what I mean when I said that no-one has ever proved that one would actually be worse off without them.
  15. It's true that Hobby are trying hard to polish up their image, but it hasn't reached the level of a Tabbert or one or two others yet.
  16. We're drifting a bit off topic here, but you were comparing what you call your 'ancient' caravans with no Tyron bands with your current one with them fitted. That's not a very fair comparison if I may say so. I can only repeat that no-one, not even Tyron themselves, have come up with conclusive evidence of the benefits of Tyron bands because they have never shown how the same outfit would have handled under the same conditions, with and without Tyron bands. At best, the bands can prevent the bead from dropping into the wheel well, although it's debatable whether even that happens with modern 'safety-hump' wheels. The tyre tread itself is not supported by the bands. Therefore, Tyron bands cannot stop the tyre from losing its tread and disintegrating. Based on my own experience with a motorway speed blowout on the caravan, I cannot rid myself of a feeling that someone is playing with legitimate concern that people have with the safety of their outfit and making money out of it without providing genuine proof.
  17. Their top-of-the-line model range is now called the Grande Puccini.
  18. The regulations that you have quoted have since been superseded by later amendments which require, amongst other things, mirrors on both sides. Otherwise, the field of view requirement that Honk kindly reproduced in his reply, wouldn't be fulfilled. The nearside standard mirror must also be adjustable from the driver's seat.
  19. I wouldn't rank Hobby in the top 3. They are by far the largest single make on the Continent, but considered fairly run-of-the-mill as far as quality is concerned. If you were going to include a Continental volume manufacturer in the top 3 then it would have to be Tabbert. If smaller manufacturers making really exclusive caravans were to be considered, then one would have to include Cabby or Kabe from Sweden in the short list.
  20. For a biggish caravan, the overhang in front and behind the axles is still going to be in the region of 3 metres, regardless of whether it's a single or a twin, so the second axle is not going to reduce stresses in the body structure by any appreciable amount. I too, have wondered why some go on about Tyron bands when no-one has ever produced any convincing evidence that one would be any worse off without them. I've also had a blowout while driving solo at over 90mph and there too, I had no problems in getting the car to come to a stop on the hard shoulder. I therefore wonder what people do to get themselves in such a mess when a blowout occurs.
  21. The ambient humidity of the air by far outweighs any local damp in the caravan structure (unless the caravan is already affected by damp to such an extent that it is beyond repair - such as flood damage).
  22. The plank of wood on two or four axle stands is a poor analogy as it doesn't take into account any suspension system. The body is so much stiffer than the suspension that for all intents and purposes one or two axles only 1 metre or less apart are not going to make any difference. The blowout that I experienced was at motorway speeds. I was in the centre lane when it happened, overtaking a lorry at the time, so it was quite while before I was able to pull over. I was then able to exit at a junction only a hundred yards or so ahead where I had to negotiate a bend in the slip road. Despite all, the caravan behaved impeccably, even though by the time I was able to come to a stop the tyre was already smouldering due to the extreme amount of flexing that it encountered.
  23. Which route would you be taking to get to Landau or Karlsruhe? One option would be Camping Freizeitzentrum Sägmühle in Trippstadt
  24. I really don't understand how panel distortion has any relevance as to whether the caravan is a single or a twin. perhaps you might like to explain your theory. Body design is the same regardless of the number of axles. As for the need for a motor mover, my 1800kg single need one just as much as a twin. There's no way thatone can move it by hand on a grass pitch. I've also not experienced any problems when encountering a puncture with a single that would warrant considering a twin as my next purchase.
  25. It's just as much an issue with a single axle. You'd be pushed to move a 2000kg single axle by hand on anything other than absolutely level smooth ground. Because of the higher contact pressure between the tyres and the ground, a single will sink into soft ground more than a twin, making it just as difficult to manoeuvre.
