RUBBER FLAP

1200R20 FLAP

Tire flap acts as a buffer between the inner tube and the tire casing. 1200-20 flap is designed to TBR inner tube which weighs 3 kg with the width of 235mm.

As the tire rotates and flexes during movement, there is a constant rubbing action between the inner tube and the casing. The liner protects the inner tube from being chafed or abraded by the rough surface of the casing. This is crucial because a chafed inner tube is more likely develop leaks, which can lead to a flat tire.

PRODUCT DETAILS

Tire liners, essential components of tires, are mainly composed of rubber and reinforcing materials. Rubber is the core material. It typically consists of a combination of natural rubber and synthetic rubber. And we use the first one. Natural rubber, derived from rubber trees, offers outstanding elasticity and resilience. This property allows the tire liner to adapt well to the dynamic shape changes of the tire during operation and effectively absorb shocks and vibrations generated on the road.

Except protecting against chafing, flap also plays other roles. It helps in maintaining the air pressure inside the inner tube. By providing a more stable and sealed environment, the liner reduces the rate of air leakage. Meanwhile, the liner, especially those made with elastic materials like natural rubber, can absorb shocks and vibrations. Last but not least, the combination of rubber and reinforcing materials in the liner gives it a certain level of resistance to punctures.

ensure safety

Reinforcing fibers such as nylon or polyester woven into the liner's structure add strength. When the tire comes into contact with sharp objects like nails or stones, the liner can sometimes prevent these objects from directly piercing the inner tube. This reduces the risk of sudden tire deflation and improves the overall reliability of the tire.
