[Land-speed] Tire Valves

[Kirkwood]

Thanks, Dale. Makes a lot of sense. So the same force wants to bend the
rubber stem over, no? Why do you want flexibility at LSR speeds?

The faster the wheel spins, centrifugal force increases. The centrifugal
load  on the center pin of a Schraeder valve can cause the valve to
partially open. Having a quality metal cap with a gasket will reduce (not
stop) air escape through the valve stem.
