Thanks, Garth and brainsarescary.
After riding about 50 miles on that wheel and tire, I’m happy to report
that I did not experience another flat. I used the two-screw method, a
valve screw inside and outside the rim, and I filed down the sharp edges of
the valve stem hole with an off-brand Drem
Sounds like a problem with the rim or rim tape. I'd replace the tape and
inspect the valve hole for any burrs or things like that.

the Mavic rims I've been riding for the last 23 years came with plastic

Thank you, @Brian Turner
@Ian, I rechecked the tire carefully for splits and structural damage.
Nothing.
@Patrick Moore, tubes with 36 patches!?! I'm very impressed. That reminds
me of the Ship of Theseus paradox: if a tube has so many patches, is it
still the same tube, and if it is not, at w
I began having this problem frequently, about 5 years ago. Nothing else
about my skills or habits or rims changed from the previous four decades,
so I've concluded that there is likely a manufacturing issue.
Thinner/less/more brittle rubber at the base of the stem or something.

I had the same thing John P describes, tire rotating in rim, tugging the
tube along, causing the valve to tilt then tear at the base. I also had it
happen twice in a day until I decided I was running the tires at too low a
pressure. Increasing PSI solved the problem.

Hi.
If what is happening to you is what happened to me, your tire is rotating
on the rim.
This sometimes happened when I was using an undersized tube like Patrick M.
mentioned, but it happened a lot to me when using modern tires on older
rims, and less when using a tubeless compatible rim. Fl
#1: tubes degrade with age. My experience says "no," at least gauging "age"
by single decades. Pre-sealant I routinely rode tubes with up to 3 dozen
patches accumulated over many years and they worked as well as new tubes.
If a tube was 50 years old I'd look at it more than quickly and casually,

These type of flats are basically the only flats I've received in the past
decade or so - mostly because I am very particular and adamant about
checking my air pressures before riding. As such, it has caused me to
retain tubes for probably longer than most folks, and I'm assuming that has

Thanks, Ryan. Yes, the narrower tube got me home, but by that point it was
only a short 1.5 miles away. I'm not confident that the narrow tube will be
ok on a greater distance because I burned through three tubes of varying
makes and specs. I'm riding different wheels until I sort this out.

I'll be interested to hear what others say about this...I should check my
X0-1's inner tubes which has been plagued with mysterious flats and at no
time have I been able to find anything embedded in the tire or issues with
the rim i.e. protruding spokes. In a lot of cases, I would make it home
