valve stem caps, threads and the stems themselves were not designed  to be

It was my understanding that the centrifugal force of a  tire spinning at 
very high speeds would cause the valve stem to push  inward and release air, 
especially on a stock Pantera Campagnola rim where the  valve stem points 
directly to the center of the rim. This is why they  came with metal caps that 
sealed the stem. That's also why they need to be  metal stems. This is the 
one of those old Pantera factoids that make sense but  who really knows!
