Not much fun that! Would it be possible to replace the inner tube and tyre?
Had the same once inflating the front tyre on my mountainbike. At the normal pressure the aluminum wheel rim burst, metal fatigue most likely. Gave me a big scare, and made my change all the rims on all the bikes in the house.
When I first started caravaning, I was told to get a pneumatic jockey wheel as they were so much better than all the others, allowing the caravan to be pushed into position a lot easier on grass etc. I never had any issues with the normal type, so never bothered.
Then I got a motor mover, and was again told that a pneumatic one was better for the mover, as it gave it less work, which in turn saved your battery, so I finally got one. I can't say if it made the caravan any easier to move, as far as I could see, it was just another tyre to have to keep checking the pressure on and a dam fiddly one at that.
We have a small step/ramp from the road, down on to the drive where the caravan parks, and as the caravan goes in front first, the Jockey wheel has a little bump as it goes down this. I used it all summer with no problems, then one freezing cold night, I was returning the caravan to the drive, and as the jockey wheel went down the little step, it blew out, shattering the plastic rim with it. I actually always assumed that the plastic rim had failed by going brittle in the cold as it was about minus 10, and was that year when the temperature had not got above freezing for about 10 days. Anyway, what ever gave out left me with a caravan half across the road, in the dead of night, with no way to easily move it.
After that, I went back to the good old trusty wide plastic wheel for many years, and have not had any problems.
The only reason I bought this pneumatic one was because it was brand new, and cheap, plus at the time, I just wanted something to make the trailer easier to move round as I was building it, and then never got round to using it.:doh
Anyway, I have managed to get the old plastic wheel into the new pneumatic frame, so with a bit of help from Mr Heath Robinson, I have something that will work.
