Is It Necessary to Replace with Aluminum Alloy Valve Stems?

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.
The owner of the wheel modification shop previously told me that aluminum alloy valve stems mainly depend on personal needs. The rubber ones that come standard with regular cars are sufficient for normal use and can last three to four years without issues. However, if you enjoy aggressive driving or frequently carry heavy loads, metal valve stems offer better stability and durability. I personally upgraded my sports car with a set of aluminum alloy valve stems with tire pressure monitoring, which look much cooler than the black rubber ones. In reality, the difference isn't significant for daily driving; the key is to check the condition of the valve stems during monthly tire pressure inspections. If cracks appear on the rubber ones, it's time to replace them, and upgrading to aluminum alloy at that point offers the best value for money.
I insist on using aluminum alloy valve stems for both cars at home. Rubber ones tend to harden and crack in winter, and last year I spent over 200 yuan fixing a leak caused by one. The mechanic mentioned that many car owners overlook this small component, which actually plays a crucial role in maintaining stable tire pressure. Aluminum alloy conducts heat quickly and is less prone to deformation when brake discs get hot in summer. A simple wipe with a damp cloth during car washes keeps them shiny, unlike rubber ones that attract dust and turn yellow. At around 70-80 yuan per set, the price is reasonable, and the peace of mind is worth it. I highly recommend them to detail-oriented car owners, especially those in colder northern regions.
