Replacing a tire valve stem is a relatively simple process that can be completed in a few minutes. A valve stem is a small, rubber or metal tube that extends from the tire and allows air to be added or removed. Over time, valve stems can become damaged or corroded, which can lead to leaks or flat tires. Replacing a valve stem is a quick and easy way to prevent these problems.
There are two main types of valve stems: snap-in and screw-in. Snap-in valve stems are the most common type, and they are simply pushed into place. Screw-in valve stems are less common, and they are threaded into the tire. Both types of valve stems are available at most auto parts stores.
