The vent spews

 

Have you noticed? When we buy new tires Whether it's a motorcycle tire or a bicycle tire, we will find the little rubber hairs on tire attached to various points and all over the rubber surface which many people especially children always pull and remove them every time.

Do you know what is the little rubber hairs? How it happened? Can we cut it? What effect does it have on driving? We have an answer for you.

These little rubber hairs that you see on every new tire. Technically, they are called vent spews which doesn't have anything to do with riding or the adhesion of the tire at all. Those little rubber hairs are a byproduct of tire manufacturing by rubber molding or steaming processes.

By this step, the raw rubber that looks flat and has no tread pattern will put in the mold by providing the appropriate pressure and temperature until it looks like a motorcycle tire that we are familiar with and the mold will have "small vent holes", rubber is injected and air pressure is used to force the liquid rubber into all the nooks and crannies. In order for the rubber to completely fill the mold, small pockets of air need to be able to escape because if there is air remaining in the mold, the tires may be in perfect condition.

The vent spews happened when the tire is pressurized in the mold. This is an important indicator that the air has been completely vented from the mold.

From the above can be concluded that vent spews can be pulled and removed. There is absolutely no effect when riding.
