How to deal with air leakage from the tubeless tire valve?

[VonLaila]

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.
