What is the function of tire hairs?
1 Answers
The function of tire hairs is to test the quality of the tire rubber by pulling them. Below is relevant information about tire hairs: 1. If they can be stretched long and are difficult to break, it indicates good rubber quality. Otherwise, it suggests poor rubber quality or expired products. 2. Tire hairs are formed during the vulcanization process of tires, where liquid rubber flows into the vent holes of the tire mold and hardens. Related information: 1. Tire hairs mainly occur when the vehicle is driven at high speeds, causing the tires to rotate rapidly. 2. The air inside the tire treads is compressed and then released, creating continuous "compression-release" noise. 3. The faster the speed and the heavier the vehicle, the louder the noise. At high speeds, the effect of tire hairs is negligible, so they do not increase tire noise.
