Mr. Tuffy bit my tube!
Okay, I have read previous comments where some people believe Mr. Tuffy
liners will cause holes in the tire tubes and others say this won't happen. Well, I am now a believer. My rear tube developed a slow leak and it turned out to be exactly at the curve of the Mr. Tuffy liner's forward tip. I can even see the line where the Mr. Tuffy liner pressed into the tube and the little slit it caused. It took awhile, but now I wonder about the other tires with these liners inside of them.

Pat in TX Pat: Never use Mr. Tuffys, or for that matter the Park tire boots, with a superlight tube. The problem you experienced will happen much more rapidly with a thinner tube than with a thick one (I guess that should be pretty obvious...). Anybody who claims this doesn't happen has been leading quite the charmed life! I'm sure Jobst can give us the details, but obviously there's a certain amount of movement/friction that occurs between the tire and tube. I've never found talc necessary for a normal installation, but suspect it might help if you have a Mr. Tuffy installed. --Mike Jacoubowsky Chain Reaction Bicycles www.ChainReaction.com IMBA, BikesBelong, NBDA member "Pat" wrote in message ...

Most 700x23c tubes are pretty thin anyway, and won't last forever.
I've had similar problem slow leaks at the seam of the tire liners.. Even with these slow leaks, the number of flats I experienced dropped way down. I did not want to stop using liners, so I tried other methods to prevent those leaks. One simple method is to reduce the pressure to, say, 100 psi instead of 110 or 120. Another is to add a cushion at the seam. At first I used the old folded dollar bill trick, then I switched to chamfering the liner's edge and covered it with a cut up piece of oldtube. I can't detect any vibration or out-of-round bumps while riding, and I don't have leaks at the liner seam anymore. |

: Most 700x23c tubes are pretty thin anyway, and won't last forever. : I've had similar problem slow leaks at the seam of the tire liners.. This is a 26" mountain bike tube, though, one made by Kenda (if that makes any difference). I don't get to ride this bike too much. It's a 1987 Cannondale without suspension. I do like to ride it when I can, but the Brooks B-17 is not yet broken in. In fact, it's trying to break ME in, I swear! From time to time, I think, "Get out the Cannondale and put in an hour on that saddle!" Pat in TX |

Use the liner in combination with a thorn resistant tube. They're thick
enough to avoid slow leaks. Thei weakness, though, is a tendency to stem failures. There's no perfoect combination! "Pat" wrote in message ...
