In fact, there are all kinds of really good reasons for inflating bicycle tyres to the lowest you can get away with short of snake bites. Right, and then you get a pinch flat or snake bite which is often unfixable in the field. All it takes is one pothole. No thanks. Do you not carry a tube? You can squeeze one in next to the heart-lung machine, rope, winch and iron rail segment used for pounding in chain-pins with found fence nails. There should be room in your pannier somewhere. Yeah, I thought snake bite meant something else out there. Like through the rim or something. I guess a spare tube is a cop out or something. Myself, I carry two and I've hit a pothole before where I needed two. |

I carry a tube. That is generally used for other riders. Since adopting thorn-resistant thick tubes plus liners I no longer have flats. However, a pinch flat would ruin $15+ worth of tube every time and I don't want that to happen. It is also a royal pain when on a tight schedule. "Sorry for being late, folks, but I hit a pot hole and got a flat. So lets get started with the meeting". Why risk a pinch flat when it can easily be avoided? After all, we also don't run our car tires underinflated. Or at least shouldn't. -- Regards, Joerg http://www.analogconsultants.com/ |

Years ago, our club used to run a family oriented picnic and bike tour of the local metropark. The picnic featured several bike-oriented games. One was to deflate your tire, then pump it up to the target pressure you chose, without the use of a gage. As I recall, there were guys who got within a couple percent of their target. -- - Frank Krygowski |
