I just pulled out my tires from storage (at home inside - not at a vendor), took off the caps to inflate and saw this: what appears to be all 4 valves missing from the stems. These were deflated before I put them away. It is not possible that these could have recessed into the valve stem right? They are screwed into the stem using the valve tool.
Does anyone have any hypotheses as to WTH happened here?
I'm sure they were not removed.
