Why do my rims have 2 valve stems?

On some racing wheels, they use two valve stems so you can inflate/deflate the tire while a pressure gauge is connected to the second valve stem. So it could be for that.

What causes a tire valve stem to go bad?

Valve stem issues are another common cause of tire problems. The valve stem is the tiny protrusion from your tire that you unscrew when you need to inflate it. A damaged or corroded valve stem can cause air to leak out of the tire, making it go flat. Loose or dirt-clogged stems can also cause tires to lose air.

Can you drive without a tire valve cap?

When the cap is removed, the valve stem is exposed and can get clogged with road dirt, grease or ice. This can make inflating the tire difficult. A missing valve cap can also lead to a slow air leak over time, eventually resulting in a tire going flat.

Why won't my tires take air?

The most common cause of this kind of leak is small gravel stones or dry grass getting stuck between the tyre and the wheel. These flakes won't be enough to completely unseat the tyre, but they will introduce a route by which the pressurised air inside the tyre could escape to the atmosphere.

How does a tire valve work?

Air gets into and stays in your tires because of the inner workings of your valve stems. When you need to inflate your tires, you place the air pump onto the tip of the valve stem. Inside, the valve opens to let air in. Then, when you take the pump off, the valve closes and stays sealed because of pressure or a spring.
