Does the Original Valve Need to Be Replaced?
2 Answers
The original valve needs to be replaced if it shows signs of aging or damage. Here are some issues to pay attention to when changing tires: 1. Choose the right tire: The specifications of the new tire should be the same as the previous one and must match the tire on the other side of the same axle. 2. Replace the valve as well: The aging cycles of the new tire and the valve are different, and the valve may develop issues within the lifespan of the new tire. 3. Pay attention to installation direction and inflation. 4. It's best to install new tires on the rear axle of the vehicle: If more worn tires are placed on the rear axle, it can reduce the rear wheels' drainage capability, increasing the risk of driving in rainy conditions. Therefore, if only two new tires are being installed, they should be placed on the rear wheels.
As a veteran driver with over a decade of experience, I don't think the original valve stems necessarily need immediate replacement, but it's best to check them regularly and consider replacing them. The valve stem is that small valve on the tire used for inflating and measuring tire pressure. Many original ones are made of rubber, and over time, exposure to wind and sun can cause them to age, crack, or deform, leading to slow leaks and insufficient tire pressure, making the car unstable and consuming more fuel. I once experienced a sudden drop in tire pressure on the highway, which nearly caused an accident, and that's when I realized this is something you can't take lightly. During routine maintenance, take a quick look every six months or when changing tires. If they feel stiff or have cracks, replace them. Switching to metal ones costs just a few dollars, is simple and reassuring, and can extend the life of your tires. Don't wait until there's a problem to deal with it—fixing it then will be much more troublesome.
