Vacuum tires are tubeless pneumatic tires, also known as "low pressure tires" and "pneumatic tires". In recent years, vacuum tires have been increasingly used on bicycles, motorcycles, cars, buses, and trucks. Vacuum tires have high elasticity and wear resistance, and have good adhesion and heat dissipation performance.
Tubeless tires are often called "low pressure tires", "tubeless tires", and "bileless tires". They are divided into radial tires and bias tires. Tubeless tires have high elasticity and wear resistance, and have good adhesion and heat dissipation performance. Especially for radial tires, because the crown angle is zero, the amount of change is small when the vehicle is moving at high speed, and it can maintain good driving stability and low friction, which is beneficial to the absorption of shock and impact and the increase of vehicle speed. Tubeless tires are much thicker than ordinary tube-type tires, and there is a layer of high-quality rubber on the surface. After inflation, the surface tension increases, and a certain pressure is formed on the inner surface, which improves the self-sealing ability to the breach. Once punctured, it is not like The gas of ordinary tires is completely exhausted in an instant, and it will last for a certain period of time, ensuring safety when driving at high speed.
Tubeless tires require high manufacturing accuracy due to the integration of the tire and the wheel rim seal, most of which are integrated die-cast aluminum wheel hubs, with high positioning between the tires and extremely small radial runout of the wheel. The comfort and stability of motorcycles with tubeless tires are much better than those with ordinary tires.
