Installing a boot in high-pressure road tires
I do most of my riding on CST Correre tires, but occasionally switch to Michelin Pro 4s for a lighter wheel and better road feel. I run them at around 105 psi.
I find the Pro 4s to be somewhat vulnerable to sidewall damage. Obviously a boot has got to be pretty smooth in order to avoid abrading the tube under high pressure. So far I've had good luck with a round REMA Tip-Top patch against the inside of the casing, topped off with a slightly smaller round piece of black friction tape. I hold them in place with automotive trim adhesive. I'd be curious to hear what you use for a boot on high-pressure tires. -retroguy |

I hold them in place with automotive trim adhesive. I'd be curious to hear what you use for a boot on high-pressure tires. I ride Conti Gatorskins on my road bike. Great tires except for the flimsy sidewalls which can cause premature failure of the whole tire. What I do is run very thick tubes with 0.120" or 3mm wall thickness. Important is that they aren't only thick towards the running surface but all around. I also apply some talc against chafing. Yesterday I swapped out a worn Gatorskin tire and the sidewall had threads chafed through and in some areas you could see through against the sun. Yet the tube kept it together. I run them around 110psi. Of course, being a mountain biker I don't really care about road feel. My road bike sees the occasional rough turf such a dirt roads or a mile of bush trail. If it's any comfort the sidewall problem also affects "modern" MTB tires. The cheaper 26" versions like Maxxis 1040N are great but you can't get those in 29" :-( -- Regards, Joerg http://www.analogconsultants.com/ In some narrow high pressure 700C tires getting a thick tube into them is nearly impossible or extremely difficult. I'd rather use something that is not too hard to repair/replace on the roadside if I have to. For ultimate puncture proofness joerg should use either solid rubber tires or fill your tubes with concrete. After all Joerg says that weight nor rolling resistance matters as long as you don't get flats. Cheers |

yeah yeah yeah keeps banging into edgy stuff running tires into cracks.
so buy a heavier tire already https://www.google.com/search?site=i...43.vefGAZOTvIs |

...So far I've had good luck with a round REMA Tip-Top patch against the inside of the casing That's kinda think isn't it? ...topped off with a slightly smaller round piece of black friction tape. Why? I hold them in place with automotive trim adhesive. You carry it around for that purpose? I'd be curious to hear what you use for a boot on high-pressure tires. AFAICT this is what glueless patches are good for. |

It avoids calling home for a ride or getting a taxi. I carry a folding scissor and a tyvec envelope. I get the envelope from the US Post Office (Express Mail or Priority Mail). The envelopes are free (no wonder the Post Office loses money). I'll cut a piece of the envelope that is twice the width of the cut in the tire. I'll place the cut piece of tyvec on the inside of the tire, covering the cut and extending beyond the beads on both sides. I'll mount the tire and inflate the tube. The tyvec is between the tube and tire. It is held in place by the beads. If it's sufficiently tight, the tyvec envelope section should be slightly narrower than the rest of the tire. This proves that the tyvec is holding the tube in place and not the tire. I'll use the scissors to remove the excess tyvec that extends beyond the rim. I've been able to patch 4 inch long sidewall cuts and inflate a 700C-23 tire to 115 psi. No problems. It's cheaper than using a dollar bill. |

Installing a boot in high-pressure road tires
Tyvek ? What are commercial boats made from ? The Rema does not wrap around tube in a U right, only glues to sidewall cut area ?
The U shape is DIY required. Try wraping around with bottom that is closed end at top tube against rim. Is held with air pressure |
