When a tire manufacturer makes a tire, a machine will be used to inject rubber into the mold, and then they apply pressure to the material so that it is evenly distributed throughout the mold. These molds are designed with small holes in them to allow air to escape through them, preventing bubbles from forming.

So tire wool is nothing more than excess rubber passing through the vent hole, cooling and hardening. So many people in the industry call them spouts.

Tire hairs are not only found on the side walls of the tire, they are also found on the tread. The tire manufacturer will use our carbide tire hair cutter for trimming. Our tire hair trimmer have very high accuracy and long service life. If you have the corresponding needs, please contact us.
