Latex tubes , Hold air longer and puncture resistant???
Looked at some tubes made by Air - B. The box describes them as
holding air 10 times longer than regular latex tubes. They also claim to be puncture and pinch flat resistant. Supposed to be lightweight too. Is this a bunch of marketing hype or??? Are latex tubes normally more puncture resistant? Thanks |

I'm not familiar with these tubes so I don't know what is different about them from normal latex tubes. Latex leaks air so fast that the normally used racing tires needed daily inflation. That latex is better in pinch flat protection should be obvious from the ability to stretch many times more than butyl rubber before it breaks. This is essentially what causes a pinch flat, the compression and lateral squeezing out rubber. On the other hand, there are a lot of bad reviews at: http://www.mtbreview.com/reviews/Tub...ct_23492.shtml Reading these makes me doubt that these people know what is happening. They talk of blowouts, which to me means "BANG". If you heard the bang then the tire was off the rim. So how can I believe this is tube related. Another writer claims the base tape cuts the tube. This is an old saw and an excuse for tire lift-offs that cause long blowout slashes in tubes. I don't know what to make of it but I don't care for latex tubes. My rolling resistance and weight is just fine and I can go on a four week bicycle ride without pumping. Jobst Brandt |

Hold air 10x longer? I don't know; both of mine blew up while I was
inflating them. Let's face it, inner tubes just aren't that exciting. Spend some time inspecting your tires for glass and crud before each ride if you want to reduce the number of flats. -Dion wrote in message ...

Hold air 10x longer? As I said, latex tubulars required daily pumping and my 700c x 25 tires make it a month without pumping. I call that at least 10x. I don't know; both of mine blew up while I was inflating them. I'm interested in how that occurred. Did you hear them make a bang? Let's face it, inner tubes just aren't that exciting. I call explosions exciting. Spend some time inspecting your tires for glass and crud before each ride if you want to reduce the number of flats. I think that is too late. If the tire isn't punctured by the time you get ready for the next ride, it won't happen. Flats occur in a short time after the sharp object engages the tire. Jobst Brandt |

Latex tubes , Hold air longer and puncture resistant???
I have a fair amount of experience with tubies using both butyl (Contis) and
latex (Vittorias) inner tubes. The latex leaked air rapidly ... it would be enough to notice (barely) after a long ride. Not so with the butyl ... their leakage was less in 48 hours than the latex in 3-4. I had problems with latex durability. I baby my tires, and rarely get road hazard flats. The latex tubes almost invariably failed adjacent to the valve stem (where it's nearly impossible to patch). I speculate that the repeated stress of pushing the pump fitting on the presta stem eventually led to the failures ... it sure wasn't something I road over when the failure zone is under the rim. That said, the latex tires seemed to have a slightly more compliant ride. But I got frustrated by the cost (now around $80 each) to replace a tire that had plenty of tread but I couldn't successfully repair. (That may be an indictment of my repair technique ... but I've never succeeded with these tires.) R / John "JP" wrote in message om... (Robert Box) wrote in message . com...

Based on my experience with tubular tires, I would say yes, definitely, except for one thing: the better tires have latex tubes, so maybe it's just that the better tires are more puncture resistant.
