valve stem leak HELP

[hisilver]

Aired down for some 4x4 today. When I aired up, one tire leaks through the valve stem now.
Tires and stems are one week old. I used needle nose pliers to turn the needle that sticks out
and that helped a little but it still hisses. What do I do, besides drive back to the tire shop?
Thanks

Head to the nearest auto parts or bicycle repair place and get some extra Schrader valves and a wrench.

You may get by by just tightening the one you have or just change it.

Maybe a bit of grit... punch it a few times to see it clears.
1-week old, take it back and get it replaced.

Earlier I was turning just the pin and by chance it was grabbing the thingy inside your
supposed to turn to tighten it. Learned something today

Thanks

They're not hard to replace. At least if they are the same as in AC systems. Just replace it. Or better yet, go back and have them do it.

Even if it is fixed now, I would go back to the store and have them replace it.
