Flat Tire Conundrum

Walter Cronkite said:

Rear tire Mt. bike. 3 flats in last 2 weeks on street. No discernable
obstructions. Can't see or feel anything on tube or tire that would
have caused the flats. Sanded baby bottom smooth any possible rough
spots. Replacement tubes bought at different stores, different kinds.
So what are some of the possible overlooked unusual reasons for a tire
to keep going flat. Small punctures at 3 diferent places on tube.
Thanks.

Got rimtape?

Use a cotton ball and run around inside of tire. I'm betting on a
teeny-tiny shard (sp?) of metal or glass.

It's those damn terrorists again. Only big government can protect you. "In
Ashcroft we trust!"

Next time mark the tire's location at the valve before you take it off, then
find the hole in the tube and reposition everything based on the valve. You
should be able to get very close to the source of the problem.

If there's nothing there, suspect thorns or steel cable strands (do you run
over an old cable at the trail head?)

You can always "cure the symptom" with Slime.

Switch tire with front. See if problem moves.

There are plenty of wild answers out there, but it's probably the most
simple answer. Your flats tires were caused by small sharp objects you
rolled over that caused punctures in your tubes, then fell out, leaving no
trace of the culprit.

Three flats in two weeks is not unheard of.

Ah yes - flatted by Occam's Razor. 😉

.... If you're in the UK, refer to this months Mint Sauce in MBUK for an
explanation.

Nice idea, usually just use my fingers....really like the cotton ball
idea.

Peace,

The mind serves properly as a window glass rather
than as a reflector, that is, the mind should give
an immediate view instead of an interpretation of the world.
