Well, if weight really isn’t an issue, people do already make airless/ air-free bicycle tires. Foam rubber of varying density to simulate different air pressures. I had a friend who considered them some years back, but they *really* are not light. -- "Also . . . I can kill you with my brain." River Tam, Trash, Firefly I think that we should encourage Joerg to buy these things and learn for himself that weight is an issue. |

Not anything new: http://www.americanindustrialtire.com/foamfilled.htm See your local skid-steer equipment dealer Thanks. AFAIK that only works with tires that have large volumes but I'll inquire. -- Regards, Joerg http://www.analogconsultants.com/ |

Those who are serious about not getting flats make their own mr tuffys from old tires How do you do the overlap? It has to be cut because the radius inside is a smidgen smaller than normal. I was thinking about making my own Mr.Tuffy from a 2nd thorn-resistant tube that is slit open lengthwise on the rim side. I'll see when the new tube gets here next week. There should be enough compliance in the rubber so there won;t be any wrinkles. Hopefully. The othe issue is that the smallest these tubes come is 700 x 23/25mm and even 23mm is a bit large if there is a another thick tube in there. -- Regards, Joerg http://www.analogconsultants.com/ |

Have you tried these? https://www.schwalbetires.com/flat-less No personal experience, but I remembered seeing the ad somewhere. I have used tires like that and have them on there now. However, they are still vulnerable to thorns entering more towards the sides and then .... phhssseeeeeooouuu. As happened on Wednesday, twice. This was not a problem when Kenda still made the tubes that were several mm thick all around. Unfortunately unobtanium now :-( -- Regards, Joerg http://www.analogconsultants.com/ |

I don't know about smugglers but yes you can buy foam to use in tires. See https://www.youtube.com/watch?v=pgv4UiDQa74 http://www.accellatirefill.com/ and I assume other sites. Thanks. Tyrfil is what Andrew brought up and I'll contact them next week. I'd like to have a similar firm tire behavior as if it was pumped up with air to 110psi. Riding comfort isn't very important, durability is. -- Regards, Joerg http://www.analogconsultants.com/ |

Riding comfort isn't very important, durability is. I'll give you a prediction - you'll discover that weight is a big problem and that you can't get the tire to properly stay in place. |
