What is a good practice to do when installing new tires?

When installing new tires, replacing the valve stems is a good practice because the valve stems are critical components responsible for holding air in the tires. Over time, valve stems can deteriorate due to exposure to heat, braking materials, and weather conditions, leading to leaks. By replacing them during tire installation, you ensure that the tires maintain proper air pressure, which is essential for optimal performance, handling, and safety.

Proper air pressure also contributes to even tire wear and fuel efficiency. Thus, replacing valve stems is a proactive measure that helps prevent future tire-related issues and ensures that the new tires perform effectively from the start.
