When I got home we were in a hurry to leave town for a couple days. For some reason I decided to pump up the tire before we left. I figured I'd fix the flat when we returned on Sunday.
Yesterday afternoon my tire was still fully pressurized. So I didn't mess with it. Was still inflated this morning, so I just went ahead and rode to work. Didn't lose any air on my commute this morning.
Weird.
I've seen that too, and ignored it telling myself that it must have been the valve not screwed down, but IME it soon goes flat again and there's a tiny hole somewhere. Nowadays, I take it off and check after a flat even if it seems to hold air.
