Quick question about valve stems

[Proximity]

Since I'm going to be replacing one wheel (keeping the same tire), do I need to buy a new valve stem or can I use the same one on the tire?

well when you replace the wheel your gonna need a new valve stem or you can reuse the old one if you take it out.

but unless your new wheel comes with valve stems then yes. the tires dont connect to he valve stem just the bead which holds the air in.
