Has my memory gotten that bad or wasn't the point of this discussion about tears in the sidewalls of tires and not large tears in tubes? I read it as fixing the thick expensive inner tube. The original question: was unclear as what was being patched. The mention of leaking air was sufficient to convince me the question was about patching the tube, especially since patching the side wall of the tire is not recommended. Customer complaint telephone call just now. It seems that we cheating lying *******s sold a woman a Rema patch kit for $2 last summer and then yesterday it utterly failed to seal a vinyl air mattress. Did it fail, ahm, how shall I say, in the middle of "something important"? -- Regards, Joerg http://www.analogconsultants.com/ |

Somehow that never worked for me - I've heard of people soaking a patch of denim in rubber solution, but I've never tried that (yet). That sounds discouraging. I have ordered another thick tube yesterday. Found it on EBay for $11. It would be nice not to have to throw away so much stuff after just one event. Self sealing inner tubes have started turning up on shop shelves - they're not all *THAT* much more expensive, I just CBA trying one. I got sick and tired of those. Especially after a green gooey mess on the garage floor. -- Regards, Joerg http://www.analogconsultants.com/ |

The failure is probably because of the inevitable movement in the rubber while riding. Recently I saw some things in the LBS that appeared to be "tire liners" I guess you might call them. I didn't enquire but looking at them in the packaging they seem to be about the width of a flattened out tire carcass. The packaging said something like "never have another flat". Something like https://www.amazon.com/STOP-Flats2-M.../dp/B0026R9DLM also https://www.youtube.com/watch?v=d5iKj_cGH2Y or maybe https://www.youtube.com/watch?v=_phPq3uzUtU Does any of that help prevent flats? -- Cheers, John B. |

In the small southern U.S. town where we once lived, we made friends with a young guy who made rustic style furniture. We bought several pieces from him. He told us about a woman who came in asking for a custom pedestal dining table. He took the job, but carefully explained to her that a pedestal table would never be as rigid as a standard four-legged table. She insisted the pedestal was what she wanted, so he built it. After taking delivery, she brought it back and demanded her money back because it wasn't rigid enough. He refused. So she went to the bank they both happened to use, and the bank manager actually transferred the money from my friend's account to the woman's without his permission. The small town south is really something! -- - Frank Krygowski |

They sure do. I my area I would never ride a MTB any farther than a few miles without tire liners. I have thick tubes plus liners. The main reason is this stuff: https://upload.wikimedia.org/wikiped...idum_seeds.jpg On the road bike only thick tubes and puncture-resisting tires which have this sort of liner built in (well, a thinner one). -- Regards, Joerg http://www.analogconsultants.com/ |
