What Causes Air Leakage Between a Tubeless Tire and the Rim?
2 Answers
When driving continues after a tire puncture, the tire bead may detach from the outer edge of the rim due to stress, leading to air leakage. Here is relevant information: 1. Tubeless Tire: A tubeless tire, also known as a "low-pressure tire" or "pneumatic tire," is an inflatable tire without an inner tube. Tubeless tires offer high elasticity and wear resistance, along with excellent traction and heat dissipation properties. 2. Reset Method: Use a high-power air pump to inflate the tire. Tubeless tires and rims are held together by air pressure; the more inflated the tire, the less likely it is to leak. New tires often experience air leakage if not sufficiently inflated. If air leakage persists after inflation, it may indicate an improper seal between the tire and rim or a small puncture. In such cases, a tubeless tire anti-rust leak sealant can be used without damaging the rim.
I've been driving for over a decade and often encounter air leakage between tubeless tires and steel rims. The main causes are rust or corrosion spots on the wheel hub surface – if the seal isn't tight, air will slowly leak out. I remember one winter when I drove a long distance and found the tire pressure had dropped upon arriving home. After inspection, I discovered rust had formed on the wheel rim edge. After cleaning it thoroughly, the problem was resolved. Another common factor is aging sealing rings. If new sealing rings aren't installed when changing tires, the rubber strips may crack over time and cause leaks. I recommend carefully checking the wheel hub condition during every tire change, using a soft cloth and rust remover to clean the surface and maintain smoothness. If frequent driving on bumpy roads causes slight wheel hub deformation, it can also affect sealing performance – it's best to visit a professional shop for dynamic balance adjustment. Regular maintenance can save a lot of trouble.
