What to Do When a Car Tire Valve Core Leaks?
2 Answers
If you find that the valve core of your tire is leaking, the most likely cause is aging of the valve stem. In this case, you need to replace the old valve stem with a new one. This involves cutting off the old valve stem and installing the new one. The rubber washer under the screw is usually the cause of the valve core leakage. Therefore, before installation, make sure to clean any debris around the valve stem installation area on the rim. Next, cut a section from the old inner tube that includes the valve stem. Then, cut a circle with a diameter of about 2 centimeters around the valve stem. Place one circle onto the valve stem and install it onto the rim. Then, fit another rubber ring over the valve stem on the outside of the rim.
I've encountered leaking tire valve cores quite a few times, usually caused by dust accumulation or minor damage. As an experienced driver, I've found emergency solutions crucial: first apply soapy water to the valve stem to check for bubbles and confirm leakage. If there's a leak, buy a new valve core and replace it yourself. You only need a special wrench, which can be purchased cheaply online or at auto parts stores. Unscrew the old one, install and tighten the new core, then inflate for testing. After replacement, regularly check tire pressure and ensure the cap is secured to prevent dust entry. For prevention, park in cleaner spots with caps on and check tire pressure monthly. Don't underestimate slow leaks - they can completely deflate tires, creating major risks during highway driving. For frequent leaks or other tire issues, visit a professional repair shop for thorough inspection. Remember, safety comes first, and timely action is key.
