What is the principle of tubeless tires?
1 Answers
Principle: Utilizing the principle of inflation and expansion, the internal gas of the tire is sealed by the outer tire sealing pad and the outer edge structure of the wheel hub, with the outer tire also serving as the inner tube. Tubeless tires are sealed as one with the wheel rim, requiring high manufacturing precision. Most are made of die-cast aluminum integrated wheel hubs, offering high positioning accuracy between tires and minimal radial runout of the wheel. Below are precautions for using tubeless tires: 1. Maintain the specified air pressure: Inner tube tires are made of high-quality rubber, offering good elasticity, strong flexibility, and a wide range of adaptability to air pressure. Even at high pressure, they do not feel as hard as conventional tires. Therefore, a pressure gauge must be used to check the air pressure. Unless punctured, tubeless tires generally do not deflate on their own. Hence, when inflating, use a pressure gauge to check and maintain the specified pressure, and never rely on touch to decide whether to add air, as with conventional tires. 2. Not suitable for overloading: Tubeless tires are wear-resistant but not pressure-resistant. Some heavy-duty trucks replace the steering wheels with tubeless tires while keeping the main load-bearing drive wheels as conventional steel-belted tires, ensuring both load capacity and driving comfort. 3. Avoid punctures: Tubeless tires should also avoid being punctured or damaged by sharp objects, and avoid contact with acids, alkalis, or oil stains, which can accelerate rubber degradation. Keep the tires clean to prevent rubber aging and extend their service life. 4. Not suitable for dirt roads: Tubeless tires perform well on asphalt and concrete roads, maintaining strong traction and stability even on wet surfaces. However, they have poor traction and stability on dirt roads, especially muddy ones. Motorcycles with tubeless tires are best used in urban areas and not on rural dirt roads.
