Inner Tubes

 What is Inner Tubes?

The rubber inner tube is the core component of a pneumatic tyre and is usually made of an elastic material such as butyl rubber in the form of a ring-shaped closed tube. It is installed inside the tyre and generates elasticity through inflation to support the weight of the car body, cushion the vibration and ensure that the tyre and rim fit and seal. With good air tightness, aging resistance and elasticity, it is widely used in automobiles, bicycles, motorbikes and other means of transport, and is a key component in maintaining the normal operation of tyres.

The role of rubber inner tubes

The main role of the rubber inner tube is to maintain tyre air pressure, form an elastic support body through inflation, carry the weight of the vehicle and cushion the vibration and impact during driving. It ensures that the tyre and rim are closely fitted to prevent air leakage, and at the same time reduces the friction loss between the tyre and rim to prolong the service life of the tyre, which is an important part to maintain the smooth running of the vehicle and to guarantee the safety of driving.
