Coming off the A7 [ Spain ] heard a pop looked in the mirrors, van tyres OK car tyres seemed OK then about 6 k further on over a speed bump and a nasty grating sound stopped to take a look, the jockey wheel had unwound itself, destroyed the tyre and tube and buggered [a technical term ] the rim, we know it was wound up ok because the previous night it had not been wound down as it was a one night stop so somehow it unwound itself, summat else to check each time we set off.

I don't think anyone did as it happened on the way down as well, but someone alerted us with a toot and point, so I have been giving it a little extra twist to lock it, but as we didn't use it that night I forgot to check it. We had been over several speed bumps already without mishap so it must have wound down.
On a lighter note, should I complain to the tyre maker? I usually expect to get between 24000 and 40000 miles from a tyre, this cant have done more than 40, do you think I should ask for my money back?

Has the actual wheel unwound or has the clamp become loose?
When we had our first Eriba we used to stop the handle unwinding by using a short bungee which was actually supplied by Mark at Eriba UK.
This stopped the handle swinging and unwinding in transit.

On one occasion in France our clamp was not tight enough and the jockey wheel assembly slid down and after about 100 km there were similar results to yours!

The handle unwound, that's a good tip about a bungee, I might try that mind you in 7 years with the last Eriba it never happened once.

I had the same thing happen twice on a new Eriba. Dealer checked jockey wheel and said that there was nothing wrong with it. Have used bungee cord on it ever since.

Doesn't the red handle do this anyway?
TonyP

No not really, Tony and it's a case of finding the best height at which to secure the handle. When on site the entire Jockey wheel assembly needs to be lowered and if the red handle is set too low in order to do the job of what the drainpipe bracket is now doing, it (the red handle) comes into contact with the main Jockey wheel securing bracket with the result that the Jockey wheel cannot be lowered enough so as to touch the ground. The drainpipe bracket actually slips between the space between the main Jockey Wheel bracket and the tube and whilst at first glance it appears that only a small amount of space exists between the drainpipe bracket and the red handle it does in fact make a lot of difference.
