Our 20 inch rubber tire tube flap stands as a precisely crafted circular rubber component, occupying a pivotal position within the tire - inner tube - rim system. Every aspect of its design has been meticulously considered to guarantee top - notch performance and enduring protection for your tire inner tubes.
One of the most notable features of our flap lies in its unique thickness design. It is thicker at the center and gradually tapers off towards both sides. This innovative design serves several important functions. The thicker central section acts as a sturdy shield between the inner tube and the more pronounced or irregular portions of the rim edge. It can effectively absorb and evenly distribute the pressure applied to the inner tube, thereby reducing the likelihood of punctures or damage caused by sharp edges or protrusions on the rim. On the other hand, the thinner sides guarantee a smooth and snug fit around the rim, minimizing any gaps that might result in air leakage or improper positioning of the tire components.
The primary function of our flap is to protect the tire inner tube. During the normal operation of a vehicle, the inner tube is constantly subjected to various forces, including the pressure from the air inside the tire, the friction against the rim, and the impact from road irregularities. Without proper protection, the inner tube is vulnerable to punctures, abrasions, and cuts, which can result in air leakage and, ultimately, tire failure. Our flap strip acts as a reliable shield, creating a physical barrier between the inner tube and potential sources of damage. It prevents the inner tube from coming into direct contact with the rough or sharp surfaces of the rim, reducing the likelihood of mechanical damage and extending the service life of the inner tube.
Function of the tire flap
-
Protect the inner tube
The tyre flap serves as a protective barrier, preventing the inner tube from coming into direct contact with the metal or sharp components of the rim edge, and thus safeguarding the inner tube against being cut or worn.
-
Extend the service life of the inner tube
20 inch rubber tire tube flap can reduce the heat generated by friction during the inner tube inflation or driving process, thereby extending the life of the inner tube.
-
Reduce gas leakage
The tire flap works in conjunction with the rim and tire to create a sealed space. It fills in the minute irregularities on the rim surface, ensuring that the air pressure of the inner tube remains stable once inflated and effectively preventing air leakage.
-
Cushioning and shock absorption
When the tire sustains an impact, the cushioning strip can disperse the stress, shield the rim and inner tube, thereby enhancing ride comfort.
