Hey guys, anyone have a rule of thumb/old wives tale for how much pressure you should run when using different types of makeshift patches? The MTB I’ve been riding has a slow leak which today got way worse (audible) and went flat in a couple of minutes. I don’t have any more patches, so I used a piece of tape over the pinhole leak, the finger of a nitrile glove over that, and more tape to hold the nitrile in place. I wanted a piece of a dollar bill, which is a lot tougher than the glove.
my understanding is when people use a dollar bill to boot the tire, they run it at full pressure.
im worried that my glove is less substantial and I should run lower pressure. I’m running 40 instead of 60 right now, riding home, the leak has slowed down considerably or stopped so far.
Obviously, I want to run as high of a pressure as I can to maximize the time before it’s too flat to ride, but maybe too high and the boot fails?

I have something that looks exactly like this and I hate it, messy and gets everywhere. Maybe it’s just old.
at this point I’m happy with the repair (25 miles) and am not going to take the tube out unless it goes flat. Don’t fix what isn’t broken.
The plan is to put another couple hundred miles on it to convince myself that it holds and then crank it up to 60 psi and see how it works there. I’m thinking about it more, and high pressure might help the nitrile glove seal. I bet it’s doing the heavy lifting not the tape, it’s a nice brand of gloves.
it will most likely fail eventually (maybe if the glove shifts), but it’s a good science experiment. It’s the back tire so no safety concern

bailing wire has been hard to find since bails went to twine....

Hmm. Instead of posting an unanswerable question that makes you out to be a jokster, why not spend that time getting a real patch? Walmart carries them in case you don't have a bike shop available.
But I'm always impressed with the bizarre stuff you make up masquerading as real to keep all of us involved.

Hopefully, all. The alternative is too sad to contemplate.

I'm showing my age When I was a kid I used to help on my uncle's farm and even then they bailed with twine. But the expression I always heard was baling WIRE, which you can still easily buy. It's used for all kinds of things, just not baling hay.

Hey Larry...
I carry a tube of super glue along with my vulcanizing cement tube in my little flat fix kits. Its just in case my unopened vulcanizing cement dries up in the tube.
I put one drop of super glue on the hole and place the patch over it. That gets me back home easy and then I just pull the patch off and patch new with vulcanizing cement. You have to keep the drop small because super glue is not flexible. I once forgot to re-patch after its use and 6 months latter, on another flat, found the super glue patch still holding.

Nothing wrong with improvising emergency repairs to get you home, many of us have done that... but once you get home you should do a proper fix. Carrying a spare tube is the best solution, far easier to deal with than patching a tube. Glueless patches are also good for emergency repairs if you don't want to mess around with contact cement.

I'm reminded of Newbomb Turk's joke in Hollywood Knights.
