What is the method for inflating a tubeless tire that won't hold air?
2 Answers
Vacuum tire inflation method is: 1. Seal the rim, lift the tire and repeatedly strike the ground to make the tire bead fit tightly with the rim; 2. Use an inflation device with a large air output. When the inflation speed exceeds the air leakage speed, under the pressure, the tire bead will gradually close with the rim. The characteristics of vacuum tires are: 1. The surface of a vacuum tire is a layer of high-quality rubber. After inflation, the surface tension increases, forming a certain pressure on the inner surface, improving the self-sealing ability of the puncture; 2. It will not be affected by the heat of the brake drum during driving; 3. Maintain driving stability and low friction, which is convenient for shock absorption and increasing speed.
Recently encountered a tricky situation where the tire simply wouldn't hold air. After some troubleshooting, I learned to first check if the valve core is clogged or cracked from aging. A valve core tool costs just two yuan - unscrew it and test airflow by blowing through it. If the valve stem base is leaking, the entire valve needs replacement. The most troublesome issue is rust/deformation on the wheel rim edge. Applying specialized tire sealant lubricant can help, but requires tire removal. Once, I managed to reseat a stubborn tire bead by hammering the tire edge with a rubber mallet while using a high-power air compressor at maximum pressure. If all else fails, professional tire shop service becomes necessary.
