|How long a tube lasts ...||Humma Hah|

|... the data are at last in, after more than a quarter of a century (years, not miles -- the miles are more like 15,000).
Schwinn thorn-resistant 26 x 1.75 x 1 3/4 tubes made in 1974 last until right about now.
I put them in about a week after getting two flats in 30 minutes due to picking up glass flats on my first century + ride. They've been on the bike ever since. The one on the rear has had 3 flats in that time, two due to nails plus a long sliver of glass on Tuesday. The tube on the front is a virgin -- no patches.
But the tire was flat again today. This time, the valve stem sprung a leak, evidently due to being wrenched about while putting 300 strokes of air into the tube via my tiny pump.
With a 150-mile towpath ride scheduled in under a month, I guess its time to spring for a new pair of tubes, huh? At 27 years old, they don't owe me much.

|I have two 1970's schwinn continentals in my garage. so there are 4 27 inch wheels. the tubes are original!!! they have been fully inflated for 30 years. probably have 2 miles on them together. |
as for my tubes, the longer i have them the more puncture resistent they are. most of them have at least 8 patches on them already. Looks like black snakes with cancer lumps
|Oh great, now I am feeling really good about the ride! ;-) nm||MB1|

|When the value of the patches exceeds the cost of the tube...||cory|

|For some reason I can't bring myself to throw a tube away until the patches overlap or the valve rips off. Last one I fixed had 13 patches on it. Got to be a point there somewhere where it makes more sense just to junk the things...|
|Well, the valve stem was debonding in this case, so ...||Humma Hah|

|... I just stuck a new tube on it. Should have washed my hands before hitting the keyboard, in fact.|

Simply amazing that you got that kind of service life out of them and were able to keep track! Prove's that there's not much reason to buy a tube unless you're in a hurry or you really shred it or damage the valve stem area.
Kinda like how long a light bulb will last if you leave it on continuously. My friends think I'm strange when I take a tube with a hole in it back to the "To be Patched" bin at home - even when people just toss them by the side of the road like the attractive lady did on the Climb to Kaiser. My pet peeve is the junk and trash that we bikers toss while on the high road to physical fitness superiority.
