Why Do New Tires Have Little Rubber Hairs?
Little rubber hairs on new tires, often referred to as “tire mold release hairs,” serve a specific purpose during the manufacturing process. These small fibers may be visible on the surface of new tires and are remnants from the mold used to shape the tire.
According to the International Tire and Rubber Association (ITRA), these hair-like projections are left on tires as a result of the mold used in the production process. The ITRA, an authoritative organization focused on tire safety and education, highlights that these hairs are not harmful and will wear off with use.
The presence of rubber hairs results from the tire manufacturing process, specifically during molding. When a tire is made, it is placed in a mold that gives it its final shape. During this process, a release agent ensures that the tire can easily be removed from the mold. This agent can interact with the rubber and leave behind small fibers as the tire is taken out.
The technical term for these hairs is “mold release fibers.” These fibers are typically short strands of rubber that remain on the tire’s surface after it is released from the mold. They are harmless and do not affect the tire’s performance or safety.
The mechanism behind the appearance of these rubber hairs involves the interaction between the mold materials and the rubber compounds. As the tire heats up during the curing process, certain components of the rubber can adhere slightly to the mold. This adhesion results in the small fibers sticking to the exterior surface.
Conditions that may contribute to the visibility of rubber hairs include the specific mold design and the type of release agents used. For instance, molds with more complex designs may leave behind more fibers. Additionally, if the tire remains unused for a longer period post-manufacture, these fibers can become more noticeable.
In summary, little rubber hairs on new tires are a normal byproduct of the manufacturing process. They result from the tire mold and are not indicative of any issue with the tire itself. Over time, these hairs naturally wear off as the tire is used on the road.
