How to deal with air leakage from the tubeless tire valve?
3 Answers
Before installation, clean the debris at the valve installation hole position on the steel rim and polish it smooth. Cut a section from the old inner tube with the valve, and then cut out a circle with a radius of 2 cm around the valve. Place one circle on the valve and install it on the steel rim, then fit the other rubber ring over the valve outside the steel rim.
Fixing air leaks in tubeless tire valves isn't actually difficult, and I often handle it myself. First, spray soapy water around the valve stem - the bubbling spot shows the leak source. If it's leaking at the core, just replace it with a new valve core costing a few dollars, using only a small wrench as tool. Regularly check that the sealing ring hasn't aged or cracked, otherwise it'll leak again soon. For severe leaks or base damage, the entire valve stem needs replacing - inexpensive but time-consuming, usually a 30-minute job at repair shops. Don't forget regular tire pressure checks; catching slow leaks early makes driving safer and saves fuel too. After years of driving, I can quickly solve these minor issues. For anything beyond DIY skills, always seek professional help - safety comes first.
When the tire valve leaks, I was a bit nervous last time, fearing a tire blowout. It's recommended not to move the car immediately; first, use a tire pressure gauge to check if it's actually leaking, then find a safe place to park. When taking it to a repair shop, the mechanic usually removes the valve core to check for damage or looseness. Replacing it with a new core solves the problem, and the whole process is straightforward. For novice drivers, it's better not to attempt DIY repairs; instead, go to a reliable 4S shop or auto service center. They have all the necessary equipment to accurately locate the leak. Also, remember to maintain your tires regularly; a well-sealed valve can prevent such issues. Safety comes first when driving, so fix any leaks promptly and avoid waiting until you're on the highway where it could be dangerous.
