Characteristics of vacuum tires: Bicycle tubeless tires are usually called "low pressure tires" and "vacuum tires", which are divided into radial tires and bias tires. Tubeless tires have high elasticity and wear resistance, good adhesion and heat dissipation. Especially radial tires, because the crown angle is zero, the vehicle changes little when driving at high speed, and they can maintain good driving stability and have less friction, which is beneficial to absorb vibration and impact and improve the speed.
Tubeless tires are much thicker than ordinary inner tube tires, and there is a layer of high quality rubber on the surface. After inflation, the external tension increases, forming a certain pressure on the internal surface, and improving the self-sealing ability of the breach. Once a tire bursts, unlike ordinary tires, the gas will not be completely exhausted in an instant, but will last for a certain period of time to ensure the integrity when driving at high speed.
