What is the replacement interval for tire valves?

Rubber tire valves have a lifespan of 3-4 years, while metal tire valves last two to three times longer than rubber ones. Over time, modified tire valves may develop air leaks. Below are the steps for replacing tire valves: 1. Before installation, clean any debris from the valve hole on the wheel rim and polish it smooth. 2. Cut out a section of the old inner tube containing the valve stem, making a circular cut with a 2 cm radius around the valve. 3. Use two rubber rings of the same size - install one on the valve stem before mounting it to the wheel rim, and install the other on the outer side of the wheel rim's valve stem. Then install the valve nut, and you may apply some sealant around the valve stem.
I've been driving for nearly twenty years, and let me tell you, the humble valve stem might seem insignificant, but it ages quickly and can easily leak air. I generally recommend replacing it every 5 to 7 years, or simply swapping it out whenever you change tires—it's the most hassle-free approach. Rubber valve stems are particularly prone to cracking, especially under high temperatures or in coastal areas with salt spray, which accelerates deterioration. Last time, my car nearly had unstable tire pressure because of a leaky valve stem. During routine maintenance, just inspect it for cracks and feel if it's hardened—these simple checks can prevent major issues. Safety comes first; replacing it costs just a few bucks, but neglecting it can lead to serious hazards. Regular maintenance is far more cost-effective than repairs, and checking before long drives gives extra peace of mind.
