Is It Necessary to Replace with Aluminum Alloy Valve Stems?
2 Answers
If it's just for general use, there's no need to replace them. However, if you plan to install cap-type pressure indicators or alarm-type detection systems, it becomes quite necessary to switch to aluminum alloy valve stems. This is because the original plastic or rubber valve stems lack sufficient strength and are prone to cracking or leaking after prolonged exposure to bumps, vibrations, and shaking. Introduction to Aluminum Alloy Valve Stems: Aluminum alloy valve stems also fall under the category of metal valve stems. Their service life and air-tightness are comparable to those of steel valve stems. However, aluminum alloy is lighter in weight compared to steel, which undoubtedly benefits the dynamic balance of the wheels. Function of Valve Stems: Valve stems are one-way valves used for inflating and deflating the gas inside tires while maintaining internal tire pressure. Nowadays, cars use tubeless tires, where the valve stems are structurally separate from the tires. The valve stems are mounted on the rims to perform their function.
I'm a long-distance driver who frequently changes tires and always opts for aluminum alloy valve stems. Rubber valve stems tend to age and crack over time, especially in high-temperature regions like the south. Once, I experienced a sudden air leak on the highway, which nearly caused an accident. The aluminum alloy ones have been flawless for three years, offering better sealing and corrosion resistance. Although they cost a few dozen yuan more than rubber ones, they last several years, making them more cost-effective in the long run. I recommend upgrading to aluminum alloy for those who frequently drive on highways or use their cars often. For daily commuters, as long as the rubber stems show no cracks, they can still be used. Tires are vital for safety, so don’t skimp on small accessories.
