It plainly states in that article that they don't have tubeless tires because of the expense of upgrading to new style tires and rims. Certainly I read it and I did read that the cost was the deciding factor... but the other poster wrote "why do you suppose that every other rubber tired vehicle has changed to tubeless?", which I was responding to: It seems to me that if a significant number of vehicles have not converted to tubeless, for financial, or whatever, reason that to blatantly argue that "EVERY OTHER RUBBER TIRED VEHICLE HAS CHANGED" is simply an example of ignorance of the subject. Hardly a statement that someone that was really familiar with the subject would make. If your argument is based, as most here appear, to be that you have an old bike for which conversion would cost more than the worth of the bike why the hell don't you argue THAT instead of using the phony arguments that they would be difficult to repair if you got the same sort of flat that would also make a tube tire worthless. The dumb-ass comment that you could fix one of these slashed open tires with a candybar wrapper is pretty inane. Or the claim that they don't get as good a performance when even the testing shows the theory of rolling resistance being less on a tire with less mass to e true as it is in every other case. I made no argument. I simply called attention to the fact that the individual that stated "why do you suppose that every other rubber tired vehicle has changed to tubeless?" simply didn't know what he/she/it was talking about. An expert in misinformation, one might say. Look, I've been riding for 40 years. I've had a lot of flats. I have never successfully repaired a slashed tire with either an innertube section or ever found a candybar wrapper that would possibly hold anything together against the inflation pressure of a high performance tire. slash ~ verb common 1. cut with sweeping strokes; as with an ax or machete Do you mean that someone attacked your bicycle with a machete? Or did you really use the term to exaggerate your description of the tire damage and make it sound much worse then the actual? As a sailor I could also repair sails with heavy needles and nylon string. I'm pretty sure you could sew up a tire well enough to make it home against inflation pressure but again - that would work equally well with a tube or tubeless tire. As a Sailor (live aboard for more then 10 years) I might repair a sail with needles and thread but string is what you tie up Christmas presents with. Since Joerg complains of sidewall slashes from the way he rides I could understand his arguing against it. But 10:1 his sidewall failures are punctures that a tubeless setup would allow him to continue riding. |

I have never successfully repaired a slashed tire with either an innertube section or ever found a candybar wrapper that would possibly hold anything together against the inflation pressure of a high performance tire. I don't think anyone is proposing a dollar-bill or candy bar wrapper boot as a permanent fix. They do work as a temporary fix until you get home. I've stuffed dollar bills into numerous tires with sizable slashes and gotten home. Sidewall cuts are not very relevant in determining whether you go tubeless or not -- except that going tubeless doesn't let you off the hook for carrying a spare tube. And yes, your repair would involve stuffing a tube and a boot inside a goopy tire with a really tight bead, but then again, maybe you got to avoid five other punctures that you didn't have to fix (who knows), so I don't see that as a huge disincentive. Again, it comes down to whether flat-avoidance and increased performance (at least under some circumstances) outweighs the expense of tubeless and inconvenience (adding sealant, stems, dealing with goop). Joerg would be a poster child for tubeless with all of the goathoads in his area. Tubeless is perfect for that sort of small, sealable puncture. -- Jay Beattie. As for performance, with a nice set of clinchers and latex tubes, its really hard to do much better performance-wise. |

I have never successfully repaired a slashed tire with either an innertube section or ever found a candybar wrapper that would possibly hold anything together against the inflation pressure of a high performance tire. My worst flat repair was on tour in North Dakota. It was the odd-sized front tire of my daughter's Terry bicycle. The cut in the tire was well over 1/2" long. I used a standard patch on the inside of the tire, plus duct tape, plus cardboard to ride something like 10 miles to a motel. There were no tires that size available for hundreds of miles. We had to contact Terry Bicycles to have one air-shipped out to the next bike shop on our route. So in the motel I sewed the tire back together as well as I could, and re-did the boots, etc. And my daughter rode that repaired tire for well over 100 miles to that next bike shop. So that's what happened with at tire with an inner tube. I don't know what would have happened with a tubeless tire. In particular, I don't know how well a patch would adhere to the inner surface of a tire that's wet with sealant. -- - Frank Krygowski --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus |

If one wants "goop" in their tires there is no need to convert to tubeless as, if I'm not mistaken, they still sell sealant to inject into the tubes. I remember when "Green Slime" first came out and folks were running about and worrying about whether they were injecting enough, or maybe too much, and bragging about never having another flat tire. Today, try going on the next club ride and announcing that, "I just put green slime in my tires", and see the reaction you get :-) |

I'm not looking forward to dealing with the goop. Frank, don't you remember "Green Slime", a sealant that one could inject into bicycle tubes and sealed leaks? I believe first marketed in the late 1980's some time and still being sold. Given that the primary advantage that is being touted for these NEW tubeless tires seems to be leak prevention it seems that the slime, that is sold, both for tubeless and tube tires, would accomplish the same thing much cheaper. Just inject it into the existing tube and ride away. No special rims, new tires, or anything. And, if you decide you don't like it just change the tube. Amazon is selling a 8 oz tube of Green Slime for $4.41 and the company recommends a 4 oz dose per tire. or some $2.20 per wheel. Match that Tubeless :-) I remember reading, years ago, glorified descriptions in the bike magazines that all seemed to promise "no more leaks" just as the tubeless folks do today. |

Avoid Mr. Tuffy liners at all costs. If you do use liners, use a thicker inner tube because the liners tend to cause flats where the two ends meet. I've used Tuffys for years, commuting in cold (but generally above- freezing) wet weather. Never had a problem such as what you describe. Inner tubes were normal thickness. They do make the bike more sluggish, but it's worth it in nasty weather. |
