herniated tyre/inner tube protruding
bit of newbie advice required - I've had my racer for 4 weeks and I
notice that there's a bulge on the side of the front tyre near the wheel rim, about 7mm across, where the inner tube is bulging and peeking out slightly through a small hole in the tyre. Is this likely to be a regular occurrence? And should I be getting a new tube and tyre post-haste, or is it something that can be lived with for a while? The bike is due to go back to the shop I bought it from, who do a free 4 weeks after purchase checkup/tune. M |

The bike is due to go back to the shop I bought it from, who do a free 4 weeks after purchase checkup/tune. It's most likely been caused by the brake block rubbing against the tyre sidewall. It should never happen if the brake is properly adjusted. It could be extremely dangerous. Take it back to the shop, and if they don't do a quick free repair complain loudly. |

Or there is a fault with the tyre. It could be extremely dangerous. It IS extremely dangerous given that the inner should be holding about 100psi - depending on the tyres - if you don't have them that hard you may get the tyre bottoming out on potholes, another possible surce of your tyre problem. Take it back to the shop, and if they don't do a quick free repair complain loudly. It needs a new tyre not a repair. If it doesn't go bang in the meantime you can re-use the inner. If you /have/ to ride the bike to your local bike shop (LBS) reduce pressure and ride carefully. -- Phil Cook looking north over the park to the "Westminster Gasworks" |

I would question the "extremely dangerous" bit. I had a front tyre fail like that on a tandem going downhill on a fireroad at some speed. Stopping was interesting but not unduly difficult. The bang though as the herniated tube burst was impressive. That was a tyre related problem but as someone else said, brake blocks rubbing the sidewall are the usual cause. -- Tony "Anyone who conducts an argument by appealing to authority is not using his intelligence; he is just using his memory." - Leonardo da Vinci |

Would you like to try it again on a tarmac road? Sudden deflation of a tyre on a road bike (racer) is no fun for the rider, especially when it involves a bend and a hawthorn hedge. :-( -- Phil Cook looking north over the park to the "Westminster Gasworks" |

The bang though as the herniated tube burst was impressive. That was a tyre related problem but as someone else said, brake blocks rubbing the sidewall are the usual cause. It would be extremely dangerous if it blew out on a bend at high speed, but of course the chances of that happening are slim, and if you'd have to be a nutter to ride fast at all with a tyre in this condition once you knew about it. Still, Maurice, change the tyre ASAP. The inner tube won't need changing but have a close look at it to see if it could do with a patch. ~PB |

Take it back to the shop, and if they don't do a quick free repair complain loudly. I've had a look, and the brakeblocks are well away from the tyre, so I don't think it's that. I do recall a couple of week backs having the front wheel go down a narrow crack which was running parallel to the side of the road. It probably took some damage on the side of the typre as it went in (and out) of the crack. It was the kind of crack my MTB wouldn't have noticed, and was a bumpy introduction to just how much more care is needed on narrow tyres! M |

And should I be getting a new tube and tyre post-haste, Yes. or is it something that can be lived with for a while? The bike is due to go back to the shop I bought it from, who do a free 4 weeks after purchase checkup/tune. If the brake is misadjusted - that is, if the brake pad, when you brake, touches the tyre rather than just the metal part of the rim - and it came from the shop that way (i.e. you haven't messed with it) they should pay for the new tyre. -- (Simon Brooke) http://www.jasmine.org.uk/~simon/ :: Wisdom is better than weapons of war :: :: Ecclesiastes 9:18 :: |

M Get it into the shop asap, if it's a faulty tyre they owe you a new one, if it's due to someone not installing the brakes correctly then you need a new tyre and a new bike shop. Of course you may have caught the tyre on something and there's a chance it may be a accident. Laters, Marz |

I had that once. I noticed it one day, decided it would last to the weekend. The next day there was a bang in the car-park (audible in the second floor of the adjacent building, where I was), and when I went to leave in the evening the tube had blown out through the hole. Fix it ASAP is my advice. regards, Ian SMith -- |\ /| no .sig |o o| |/ \| |
