The Lower Eastern Times Opening The Third Eye
Have you observed that when we purchase new tires, whether for a motorcycle or a bicycle, we often notice small rubber protrusions on the tire’s surface? These tiny rubber hairs are found at various points all over the tire, and many individuals, particularly children, tend to pull them off.
Ever wondered what these little rubber hairs are, how they form, and whether they can be cut without affecting driving? We have the answers for you.
The small rubber hairs, technically known as vent spews, are not related to the tire’s grip or performance. They are a byproduct of the tire manufacturing process, specifically during rubber molding or steaming procedures.
During manufacturing, the initially flat and treadless raw rubber is placed in a mold, subjected to appropriate pressure and temperature. This process transforms it into the recognizable motorcycle tire. The mold contains small vent holes through which rubber is injected, and air pressure is used to ensure the liquid rubber reaches all parts of the mold. To prevent air pockets from compromising the tire’s quality, these small vent holes allow trapped air to escape.
Vent spews occur as a result of pressurizing the tire in the mold, indicating that all air has been successfully vented from the mold. Importantly, these rubber protrusions have no impact on riding and can be pulled and removed without affecting the tire’s performance.
