What if the valve stem on a tire must exert a certain force on the air within to prevent any of that air from leaking out?
The valve in a tire valve stem is a Schrader valve, it is a one way valve that is spring loaded shut. If air is leaking out, it is usually dirty and the dirty is holding it open preventing it from sealing/ or never reinstalled properly during last service. There is a tool to remove the valve, for quick deflating/servicing. Use soapy water or cleaner like windex/fantastic to check if it's leaking. If it is it will foam/bubble up.
How do bellows valves work?
Bellow is similar to a hollow flexible hose. It functions like a vertical diaphragm (parallel instead of perpendicular to valve stem). It seals with the valve stem at one end, and seals with the valve body at the other end. Therefore, it allows a small relative move between valve stem and body, but prevents fluid from leaking across bellow surface. The move pushes seat or stem tip for valve to close or open. --SteveX

How do you change valve seals on a Hyundai elantra 2006?
Valve stem seals? Either you change the valve stem, or you change the valve core. Depends on where your air is leaking from. If it's the valve core, you simply take a valve core removal tool or pocket screwdriver with a valve core removal end (either one can be had cheaply at an auto parts store), uncscrew the old valve core out, insert the new valve core, and tighten it in. If you're replacing the entire valve stem, best to let a tire shop do this, as your tire will have to be dismounted, remounted, and balanced again.
Symptoms of Valve seals leaking?
If the valve stem seals are bad the intake valves will "suck" oil into the cylinders. One common indicator of worn valve stem seals is to take your foot off the accelerator for several seconds when going downhill, then watch for smoke when you step on the accelerator again. If you see a puff of BLUISH smoke, you probably have bad valve stem seals. The catalytic converter can become oil fouled so that would be another indicator that you might have valve stem seal problems.
