Latex innertubes more puncture resistant?
So are latex tubes actually more puncture resistant than butyl tubes? Recently I have gotten at least one flat every time I ride in the rain. I have tried 6 different brands/models of tires and I have suffered at least one flat with each one. These are punctures from small sharp stones (don't get me started on whether the are flints or not!) that get embedded in the tire and cut through to the tube. I am going crazy. I need to find a good performance oriented tire 700x23 or 25 that survives wet weather with the types of sharp stones all over the place here. Or if latex is more resilient, maybe it will do the trick. Solutions that increase rolling resistance significantly are not an option. Joseph |

Joseph My winter tire - Vittoria EVO-KX. 7000 km on the first rear, two glass shard flats. 9000 on the front, still going strong. Second rear 2000 km and fine. They do like a little extra pressure, compared to usual rain/winter tires. Excellent rating for crr in Le Cycle. Lately I've been using the Vittoria Pave EVO CG which I like for the extra wide casing. I've got about 2000km on them (the rear is soon ripe for replacement) and they are great except both times it rained I got a flat. I guess the positive way to look at it is I rode 2000km with only 2 rain days! (I usually use another bike in the rain.) I'd expect the Pave to be at least a bit tougher than the KX, or do you suppose it's just a bigger casing and that's it? Joseph |

Joseph Dear Joseph, Latex tubes resist pinch flats better than butyl tubes because latex squashes more than butyl before it splits. In other words, a stiffer butyl tube of the same thickness will split before a squashier latex tube if you drape them over an anvil and hit them with a hammer. Neither kind of rubber stands up to cutting flints or piercing thorns. Bicyclists have complained about flints for over a century. Even on solid tires, round-the-world highwheel-riders hated flints: "Thomas Stevens crossed the Austrian frontier the morning of the 28th of May, expecting to reach Vienna in about three days. The roads about Munich are described as abominable stretches of loose flints." --Outing magazine 1885 http://www.aafla.org/SportsLibrary/O...5/outVI05t.pdf Complaints about flints increased after pneumatic tires appeared: "The surface of the road however improves [in Brittany]. He [the rider] must keep to the route Nationale, or he will fall among the flint stones east of Chinon. . . . Would that the roads were strewn with this rock [probably limestone] instead of the flint that covers them from this point on to Chinon, for a viler road I have not found in France!" --Outing magazine 1897 http://www.aafla.org/SportsLibrary/O...outXXXI03g.pdf "In parts of England the flint roads play sad havoc with your tires, and a special tire is largely used for touring in those localities." --Outing magazine 1898 http://www.aafla.org/SportsLibrary/O...tXXXII03zc.pdf "The roads are full of sharp little stones — the French call them 'silex' — and punctures are plentiful." --Outing magazine 1899 http://www.aafla.org/SportsLibrary/O...utXXXIV03h.pdf Most threads about flint-flats end up recommending thicker tires with built-in Kevlar belts or tough plastic tire liners.

Latex innertubes more puncture resistant?
Hi Joseph,
If you want to talk about tubes then tubes. If rather you want to talk about tires then the worst puncture tire that I bought and had numerous flats was hutchinson carbon comp. My bike came with irc red storm never got a flat. Right now I am using continental ultra. A week ago I hit a stone in the rear tire. It poped like a bullet out from under the tire "twang." The tube developed a slow leak and I just replaced it rather than try to fix it. I don't know if it punctured or the stem seal is bad or what. For that one I am not blaming puncture. I kind of like the continental ultra for the ride and the price. I tried some of the forte' road tire by performance bike for my peugeot which runs the older 27 1/4" rim, the tire however is 27 1/8", I don't believe any big difference, these tires are good riding tires. I haven't had a flat on the performance bike brand tire yet. Talking about tubes, I was using the performance brand tube. I flatted about 20 miles from home. I pulled out my brand new tube from my saddle pack (6months in the pack), and installed it on the bike and proceeded to pump it up. It wouldn't hold any air. I kept trying, thinking it was the pump, I checked if the pump was the problem. The pump wsa ok and then I kept pumping and listening for air escaping. I couldn't hear anything, and the tire was not inflating even the least bit. So I finally removed the tube from the tire again (the new tube) and it had numerous 1 inch long splits in the seam. I don't know why, but I walked in my stocking feet to the nearest bike shop and - it turned out to be Performance bike about a mile away. They gave me a replacement tube. Since then I changed out for continental tubes. Haven't had a flat on the continental tubes yet. wrote in message ups.com... So are latex tubes actually more puncture resistant than butyl tubes?

I dunno about the tubes, but some friends of mine who ride tandems tell me
their longest lasting tires are alligators or gatorskins, or something like that. You might want to look up those terms. I think the tires have extra strong casing. |

Joseph I remember a long time ago, someone was marketing a latex tube that they claimed was more resistant to punctures than regular tubes. They showed pictures in their advertising of a sharp object stretching their latex tube and penetrating a standard tube. They were expensive and our limited testing was inconclusive. The other issue was having to pump up the tires before every ride. Chas. Chas. |

I remember a long time ago, someone was marketing a latex tube that they claimed was more resistant to punctures than regular tubes. They showed pictures in their advertising of a sharp object stretching their latex tube and penetrating a standard tube. I used to use the Air-B butylized latex tubes (the advantage of these over regular latex is that they leaked down slower, but still more than regular butyls). I stopped using them because, on several occasions, when I flatted the tube ripped open in one long rip. I think they are more fragile than regular butyls and thus I do not want to risk a sudden flat which could cause a crash. |
