its common for that to happen. i work in a tire shop and we see it all the time. especially if you rub against a curb or have annoying kids in your neighbourhood. whenever you get your tires replaced its always a good idea to have new valve stems put in.
It WAS a slow leak until I left work at around 8 tonight. Nothing like changing a tire in the rain. I went Hulk on that. Even turned green and ripped my clothes!
