A good question: what are those blades or hairs on new car tires? The answer is quite simple
Anyone who has experienced the joy of fresh tires knows them. The blades or hairs on new car tires. But what are they doing there? Starting with the unofficial function: they show that the tires are actually new. Handy as a sales argument for a car. In reality, the blades or hairs have no function. It is a by-product of the production process.
A car tire consists of several layers of rubber with some other materials such as polyester and steel. In the factory, the layers are put together and put in a mould. The tire is heated in the mold to give it its shape. The air escapes from the mold through small channels. Melted rubber remains in both channels, and you can see that on the tire. Some people call them flubs. Oh, and plucking the hairs won’t hurt. Although those things are often still very tough. Ken Block can help you with that.
