Do all new tires have fetal hair?

New tires don't necessarily have hairiness. With the development of technology, many advanced manufacturers have solved this problem.

Hairiness refers to the raised rubber strip on the tread of a new tire, and the determining factor of its quantity, length or existence is the tire production technology. The length of fetal hair is generally about 10-20mm, and the diameter is about 0.6-1.2mm. ..

The formation of fetal hair is caused in the last step of tire manufacturing-vulcanization process. With the upgrading and optimization of the die vent by the manufacturer, the shortcomings of the original production process were overcome, and a tire without fetal hair appeared. For example, Cooper C 1 is a tire without fetal hair.

With the development of technology, many manufacturers have improved their production technology for the sake of beauty. It is no longer suitable to judge whether a tire is refurbished according to the original method. Now it is suggested to check the tire pattern and production date to reduce the error rate.

Moreover, practice has proved that the lack of fetal hair will not affect the tire grip and the direction of tire noise, because the role of fetal hair itself in these aspects has been ignored.

Finally, technology is constantly improving, so we should keep learning, and don't joke at a certain point because of experience.
