Herein, what is a valve stem thread?

How does a tire valve stem work?

A valve stem is a self-contained valve which opens to admit gas to a chamber (such as air to inflate a tire), and is then automatically closed and kept sealed by the pressure in the chamber, or a spring, or both, to prevent the gas from escaping.

Can you drive without a tire valve cap?
