I had a flat on Sunday - patched it and everything was fine. The next day it was flat again. Took the tube out and inflated it, put it under water, etc, and no leak was detected... Put it back on and it's flat again this morning!!! WTF?<br>
Should I just relpace the tube? I can't figure this out! Maybe it's the valve? I don't know.<br><br>
Any thoughts?
