Tubes are cheap. I can always find a use for an old one. I just don't get riding on tubes with 15 patches on them.

Maybe it's because I blow a tube about once a year across both my bikes and my kids' bikes and its just cheap to replace one. Maybe if I lived in a place with goat heads and cactus needles and nails everywhere and had a punctured tube every other week like some people it would get expensive to be constantly replacing tubes.

Does anyone here patch them until you can no longer see any of the original rubber?
Cheap is relative; tubes are $10 a pop (geddit??) and patch kits are $2, and I need that extra $8. That said, I replaced a tube last month after the 5th flat.

It was old. This is an actual thing that happens to rubber. I swear I'm not making this up. Rubber gets old and brittle. I could even feel the rubber near the seem rip was tougher and less pliable.

People, it's just an old tube that was undersized for the tire it was in. It had a weak spot that failed.
I've had bicycle tubes fail due to old rubber twice.

One just hissed when it was aired up with my compressor. Turned out the rubber near the valve separated.

Another one went bang as you described when I was filling it with my hand pump. Never got above 50 psi when that sucker let loose. Can't recall the location of the failure.

It must be a matter of how often flats occur.

For the once a year I deal with them (maybe) it's just easier to get a new tube.

If I had multiple flats a year...yeah I can see not wanting to buy a new tube all the time.

Tubes are not nearly as cheap as patches. Everybody has a different utility function for money vs time, I am at the extreme cheapskate end of the spectrum. I will patch a tube indefinitely many times, as long as it's an 'easy' patch job. If I apply a patch and it fails (see above carp about holes right on seams/ridges), or if a leak develops at the stem, or a new puncture is so close to a previous patch that a new patch would have to overlap, then I throw it out.

No...it was definitely a pinch flat.

(Numerous people who weren't at your house that day told me so)

Everyone sneers at the ancient "pinch test" for tire inflation but it has its advantages. (That and use a pump that isn't too easy. Most cyclists can benefit from the additional upper body work anyway.)

That said, I can over-inflate my tires with nearly all my pumps. Zephal HPs and HPXs can go very high if you are willing to so the work. My Specialized floor pump will get to 120 with no difficulty and the gauge can be rotated. Mine has lost its calibration,. I don't know if my 100psi is 100 but I set it to pass the pinch test so I don't worry.

Good practice - always do the pinch test after you pull the pump off. It's easy and the more often you do it, the more accurate your "gauge" gets. (Other pluses - that gauge isn't pump dependent and much harder to lose, even if you forgot to zip up your tool bag.

I patch tubes because it is simple to do and I don't discard a perfectly usable tube.

Are these fancy tubes? Is there a tube tax in your state that I don't know about?

Most websites have regular tube discounts on good brands, so whenever I order something I'll usually thrown in a few Vittoria, Continental or Michelin tubes for $4 or so...

I'm going to best you all, and say the air ended up outside of the tube because.............

It didn't remain inside the tube (or at least most of it did not).

You're welcome.

How do you know the room's air wasn't escaping INTO the tire?

I mean it probably didn't...but you weren't there, man! You know KNOW!

You should not have filled the tire with nitrogen. This is known to cause inert toobs to assplode.

If the rooms air escaped into the tire, wouldn't the OP be dead?

Not if he is a robot. Although from the his other post yesterday (taken after the wheel asploded, I assume), it looks like he might be a dead robot.

Don't mess with me on Weird Al lyrics. Because there's no killer app I haven't run. At Pascal, well, I'm number one. Do vector calculus just for fun. I ain't gotta *** but I gotta soldering gun.

Incidentally....good Weird Al songs to bike to...

CNR
Nature Trail to Hell (great for off road mountain biking)
Dare to be Stupid
I Love rocky Road (great for gravel biking)
You Make Me
Most of the polkas

Edit: *** is censored? g a t? An obscure slang for a gun? But not the word gun itself? Is this a government run website? Because this is how government runs stuff.

Seen Weird Al in concert 4 times, and he's definitely in my riding music mix.

Me too!

Did you catch last year's Ridiculously Self Indulgent Ill Advised Vanity Tour? Where he only sang his original non parody stuff? No costumes or the video screen on stage?

Saw him perform Albuquerque and The Night Santa Went Crazy live. Also saw him do Dare To Be Stupid performed like a Grateful Dead song

This year he's touring with a symphony. Seriously.

I missed that tour, and I really wanted to go (I literally moved about the time he came to where I was...last year sucked).

I will most definitely catch him the next time he comes through here though.

I pay ~$6/tube and 25 cents/patch. Patches also make finding the cause of the flat far easier. They tell you exactly where to look for that almost invisible tire wire or tiny piece of glass. And two patches at the same place or same distance from the valve? OK there's an issue with the tire or rim and you know where it is.

Many of my tossed tubes have half a dozen patches. $6 X (6) - $0.25 X6 = $34.50 I didn't have to spend. And if they saved me one incident of a tiny wire causing more flats than I had tubes (or CO2 cartridges - I presume those without time don't use pumps on the road) possibly a whole lot more $$s (or a spouse's resentment).
