A common missconception about tires is that when you buy a tire you are getting a "New" tire. That tire could have been in a warehouse for years before you bought it. There is a number on all tires that tell you when the trire was made. Same could be said for the valve stem.....they could be very old. I have always wondered why when you buy a new tire....they alway sell you a new valve stem. Is that because the old valve stem "Needs" to be changed or are they just trying to make a little more money?

I don't have clear picture of what you mean. Did you take the old valve stem off the tire rim and then put a new stem through the rim? If not.....I think you need to do this.
