• But you can't put as much pressure on it as compressed air, you've got before photos, see what it's like inflated, if it's all good then it's all good, if it's not then get a refund.

  • Thank for your help, i installed the tyre tonight and everything so far seems good.
    I was maybe over panicking :)
    Tube is for 47c max, tyre is 50c. Inflated to 2.5 bars, it won't explode ? I did put 25c tubes in 28c without issue but once again, it for my kid carrier bike so don't want to get trouble.

    Overstretching tubes won't explode them instantly until you get to a much bigger stretch than that, but they can puncture more easily and deflate quicker when punctured.

    Put it this way.

    I fitted a 700 x 23mm inner tube on a 650b 47mm tyres as I took the wrong tube.

    I did not die.
