Tyre popping off rim - oops!

    I went for a ride this morning and stuffed about 85psi into my rear Michelin 700X28c on the tourer.

    Got about 5 miles in and was aware of tyre rub. When I stopped the tyre was off the rim for about 2 inches on 1 side and the tube was poking through! I had to deflate it, reseat they tyre and pump it up to about 50psi with the hand pump.

    I was a bit surprised as the tyres are rated to up to 87psi on the sidewall.

    Perhaps I hadn't seated it properly when I fitted it or perhaps the tube wasn't located properly?

    Whatever the reason, it's a first for me.

    Try refitting the tyre with talc then running it along the ground half-inflated before pumping up.

    The middle bit

    I've had that happen 3 or 4 times on my Conti Contacts. Has only happened when i've been a bit enthusiastic with the track pump. Doesn't half turn heads when your rear tube explodes.
