Expensive at

1/10" or
so with REMA patches works but only for 3-6 month, then they hiss
through
and I get a slow leak. I can ride home but it's annoying.

Somehow that never worked for me - I've heard of people soaking a
patch of
denim in rubber solution, but I've never tried that (yet).



Canada started making their money out of plastic. Works the charm for a
temporary patch in a slit tire.


so does a US dollar bill


True.

I dunno about that. Something like this 2" x 6" patch?
http://www.gemplers.com/product/9D/Rema-6L-x-2W-Oval-Tube-Patch
It requires cold vulcanizing fluid 7A or G50T.
http://www.gemplers.com/product/7A
http://www.gemplers.com/product/G50T
At 10 patches for $25 plus chemicals, talc, shipping, and taxes,
methinks using $5 Canadian polymer banknotes might be cheaper.

Notice that the instructions at:
http://www.gemplers.com/tech/tube-repair.htm
are for an automobile tire inner tube. For bicycle tubes, methinks it
might be best to apply the rather large patch on a rounded mandrel
with a diameter slightly smaller than the bicycle tire, instead of the
traditional flat surface. That should prevent any wrinkling,
stretching, or excess tension on the patch when installed and
inflated.


Has my memory gotten that bad or wasn't the point of this discussion about tears in the sidewalls of tires and not large tears in tubes?


About tears in the tube caused by side wall failures. Meaning they
aren't punctures but slits. Not a problem to fix a thin tube but with
thick tubes the patch then becomes the weakest member of the stack-up
.... and eventually fails. The failure is probably because of the
inevitable movement in the rubber while riding.

I read it as fixing the thick expensive inner tube. The original
question:

was unclear as what was being patched. The mention of leaking air was
sufficient to convince me the question was about patching the tube,
especially since patching the side wall of the tire is not
recommended.


Customer complaint telephone call just now. It seems that we cheating
lying *******s sold a woman a Rema patch kit for $2 last summer and then
yesterday it utterly failed to seal a vinyl air mattress.


Did it fail, ahm, how shall I say, in the middle of "something important"?

That sounds discouraging. I have ordered another thick tube yesterday.
Found it on EBay for $11. It would be nice not to have to throw away
so much stuff after just one event.


Self sealing inner tubes have started turning up on shop shelves -
they're not all *THAT* much more expensive, I just CBA trying one.



I got sick and tired of those. Especially after a green gooey mess on
the garage floor.

Recently I saw some things in the LBS that appeared to be "tire
liners" I guess you might call them. I didn't enquire but looking at
them in the packaging they seem to be about the width of a flattened
out tire carcass. The packaging said something like "never have
another flat".

Something like

Does any of that help prevent flats?

It could be worse.

In the small southern U.S. town where we once lived, we made friends
with a young guy who made rustic style furniture. We bought several
pieces from him.

He told us about a woman who came in asking for a custom pedestal dining
table. He took the job, but carefully explained to her that a pedestal
table would never be as rigid as a standard four-legged table. She
insisted the pedestal was what she wanted, so he built it.

After taking delivery, she brought it back and demanded her money back
because it wasn't rigid enough. He refused. So she went to the bank they
both happened to use, and the bank manager actually transferred the
money from my friend's account to the woman's without his permission.

The small town south is really something!

They sure do. I my area I would never ride a MTB any farther than a few
miles without tire liners. I have thick tubes plus liners. The main
reason is this stuff:

On the road bike only thick tubes and puncture-resisting tires which
have this sort of liner built in (well, a thinner one).

I don't know. This happened just before we moved out of state, so I
never heard the final result. He certainly should have sued!
