What is the name of the tire inflation nozzle?

The nozzle used for inflating tires is called a tire valve. Additional information is as follows: Tire valve: The tire valve consists of three main parts: the valve body, the valve core, and the valve cap. It serves as a one-way valve (check valve) for inflating or deflating tires with gas or liquid, while maintaining and monitoring internal pressure. For tubed tires, it is installed on the inner tube, while for tubeless tires, it is mounted on the rim. Structurally, it can be divided into two types: rubber-metal valves and metal valves with rubber pads. The former is used for inner tubes of car tires, while the latter is mainly used for inner tubes of truck tires. The internal structure of tubeless tire valves is the same as that of ordinary valves.
I often encounter insufficient tire pressure when driving and need to inflate the tires. The specialized component used for inflation is called the valve stem. The name is quite vivid, resembling a "mouth"—when the air pump presses down on it, inflation begins. Over my years of car ownership, I’ve found that valve stem maintenance is crucial, especially ensuring the small cap isn’t lost. Without it, dust can enter and cause air leaks, leading to low pressure that accelerates tire wear and compromises driving safety. Every time I wash my car, I check the valve stem’s condition by applying soapy water to see if bubbles form, which indicate a leak. When inflating, it’s best to use a standard pressure gauge rather than relying on guesswork. Follow the recommended values on the car door label to significantly extend tire lifespan.
The component used for inflating tires is called a valve stem. I've encountered many friends who confuse its name. It is typically made of metal or plastic and contains a small internal valve that must be pressed down to allow air in during inflation. After prolonged use, the valve stem is prone to aging and deformation, leading to slow leaks and affecting tire performance. I recommend regularly checking tire pressure—using an accurate pressure gauge is more reliable than relying on experience. In summer, tire pressure increases due to heat, so measuring it in the morning when the car is cold yields more accurate results; in winter, the opposite happens, and pressure drops, so it's best to check monthly. If the valve stem is severely worn, replace it with a new one. Choosing high-quality materials can prevent frequent issues, saving both money and hassle.
