[AT] Confessing a complete lack of knowledge here

Larry,
Now, that may be true and since I didn't see the event, and the fact 
that the valve stem is located on the tractor side of the rim, making it 
harder to see and operate, might be a real factor.  I thought I would 
wait a few days and then check on the tire and then I'll investigate 
more thoroughly.  My uncle is beginning to get a bit feeble so my aunt 
does a lot of the "grunt work" .
