Two punctures in one day - one, in the arvo, on the trip to Kingsford
and one, at 0530, on the way back from Kingsford! Fortunately, I was carrying 2 spare tubes. Dunno why I was carrying two tubes but I am glad I did. Both punctures on the rear tyre. Serves me right for not checking the inside of the tyre after the first puncture cos I found a piece of glass embedded on the outside of the tyre the second time round - about 2mm long sitting flat and barely noticeable/"feelable". |

I don't like to feel tyres/tubes knowing the area is full of glass when I ride on those cycle ways, hate cut fingers. I only have a pump and a repair kit so its imperative that I check where the hole is and what the cause was, there is a limit to the number of patches in one's kit. |

I have sliced my finger once about two years ago but there is really no other way I know of to figure out if the inside of the tyre wall is clean. Nowadays, I tend to feel a bit slower and try to use the digits on left hand as the sacrificial digits. I only have a pump and a repair kit so its imperative that I check where the hole is and what the cause was, there is a limit to the number of patches in one's kit. How do you check for holes when you are on the road? I find it easier to just swap the tube and than do the hole repairs when I have some water handy to do the bubbling test. |

How do you check for holes when you are on the road? I find it easier to just swap the tube and than do the hole repairs when I have some water handy to do the bubbling test. I find I can often find a leak without water by running my hands very lightly over the inflated tube. The air coming out of the hole makes a hissing sound when there is a finger almost blocking the hole. Wetting your hand with a little water from a drink bottle helps. If I can't find it that way, it's a slow leak, and I just pump it up again to get me home. I do carry a spare tube, but I too have had two or more in a day[1]. Last tie I had a puncture though, the spare tube had been folded up in the seat bag so long that it had perished and split along the fold lines... sometime you just have to patch. Moike [1] a couple of years back I rode through a patch of bindi-eye seeds at Brimbank Park. Got two punctures at once. Replaced the tube, rode off through the rest of the patch of bindi-eye..... one more. It was after that I doubled the capitalisation of my bike by purchasing tyres with kevlar bands below the tread, |

I pump up the tube and run my wet hand over the tube to find the hole. Then I look at the tyre for the problem. Its not much use placing a new tube in if you don't check just to get another hole from the in bedded problem, checking it this way just pin points where to look with more accuracy without running your fingers all around the tyre.. |

My technique is to pass the back of my hand over the inflated tube - not touching, but as close as practicable. The tiny hairs on the back of the hand are extremely sensitive, and you can feel the air flow from even a very small hole. The other advantage of this method is that it works with noisy traffic passing close by. John |
