The black back tired tyre

Imagine you are riding a bike along a river on a flat cyclepath by a beautiful monday at the end of the afternoon. You realise suddenly that you go slightly up and down with a frequency that seems to match each rotation of the wheels of the bike.

1- You are sick and imagine things, maybe the moussaka at lunch contained strange spices and you have hallucinations...
2- Too much affective problems give you the hiccups...
3- a tyre is not a perfect circle anymore... ay! another hallucination

I stopped and checked what was up. Nothing looking strange at first sight... but what is that crack there?
the nylon fibers appeard visible where it should not have... the sceptics would say :"again a stupid young guy that blocked the wheel while braking" but no, the rubber is just swollen.

This must be another curiosity that only happens to me. Well that tyre must be 10 years old +/- and still not smooth. Ach! things are not as good as before ;) (C'était mieux aaaavant!)

i just imagine myself going down the hill at full speed and the nylon cracking all at once with the inner tube protruding and exploding like a chewing gum with me sliding on the ground a bit further...

KaMiKaZzZzZe

The brake full of oil... why wasn 't it stopping me? maybe i overfilled the gear box with oil... and the holes in the tyre (my finger could pass through it ;) the amount of broken nylon fibers was quite huge... how didn't it break earlier!!!!
