flat yet no leak?!(11 posts)

flat yet no leak?!wolfereeno

This has happened twice this week. Overnight my tire went totally flat. So I took the tube out. Pumped up, ran under water and saw no leak. I remounted tube and pumped to 120 psi. Tested again. No leak. Rode 60 miles - no probs. Next morning totally flat. What's going on?

Thx

got to be a leak.Check the tube in a pot not under a faucet!
You will see a slow leak.I would just replace the tube!Check tire for a thorn.Sometimes you can see where the leak is on the tube and check the are on rim and tire better!

SOMETIMES THE VALVE WILL LEAK ONLY AT HIGH PRESSURE!

i think it the valve...it no leak when u ride b/c the metal get hot expands locks out air but when it cools..it leak..right? do u have a long stem valve w/ a remaveable head? those things suck for holding air in..have even had them shoot off when i open to in flate b/c they losened while riding

CO2 leaks out completely after a couple of days but it is not your case.

Dont you like to know why your replacing something.
Its like a puzzle!At least I like to now why something is broken and why I am replaceing it.Rather than just mindlessly throwing parts at something until it works.

New tubes are under 5 bux.... how much is your time worth? And how much of it have you spent in frustration trying to find this hole?

Get a new tube and be done with it. Just check the tire for any glass or thorns and the rim for burrs and change out that tube.

Some things aren't worth the headache of fixing...

Do you have valve extenders?
