    Maybe a weakness? Was it an old tube?
    Over inflation? What PSI was it?
    Hows the tyre looking?

    That looks like an overpressure to me, or it's a flaw in the tube wall

    A few years ago I went through a period where I could coma back to the bike and find the tyre flat with the tube looking much like this. It once happened just after I had left the house.
    I couldn't work it out, blaming poor tubes, until one day in the garage I heard a strange noise. I looked about and found the tyre being forced off the rim with the tube gradually being exposed. Once enough of the tube was poking out it of course was pinched twixt rim and tyre and so burst. I still have no idea what the cause was.

    was it a specialized tube?

    I had one blow up in my hand as I was fitting the wheel back in and it was only at 40psi

    If part of the tyre bead isnt seated properly and/or it slips over the rim you get a nice explosion even if not overpressured ... Done it once in my garage :shock: Ouch :evil:

    check the tyre bead aswell cos i've had a couple come through the sidewall and the tyre has let go of the rim before

    it worries me that I had to get 110 psi in the other week to get the tyre to seat

    I hid round the corner of the shed with the pump

    I got continental explorers with the anti puncture side walls and they are propper hard to get on and even harder to seat
