Why is there a little Mao Mao next to the tire? What's the use?

The "Little Mao Mao" on automobile tires is mainly found in new cars, especially the new cars just mentioned from the 4S shop, and there may be many Little Mao Mao on the tires. In fact, in the automobile industry, such as these little Mao Mao on automobile tires, there are also professional terms, which are usually called "fetal hair". For the fetal hair on the tire, it mainly means that during the tire processing, a large number of tiny fetal hair will be formed on the mold just after the newly produced tire is taken out of the mold. Generally speaking, the fetal hair can be shaved off when producing tires, but in order to save manufacturing costs, tire manufacturers have not specifically done this step.

As for the fetal hair on the tire, it actually has a certain purpose and can be taken seriously as a car owner. Automobile experts explained that in theory, car owners can judge the quality and aging degree of tires by pulling tire hair. If the fetal hair can be pulled for a long time and is not easy to break, it can be judged that the tire quality is excellent; On the other hand, if the tire hair breaks when pulling by hand, it means that the rubber quality of the tire is not good, or the tire is aging, reminding the owner to replace the new tire in time. In addition, automobile experts said that the fetal hair on the tire will not affect the driving safety, and the owner can rest assured of the fetal hair phenomenon.

Since the tire hair on the damaged tire will not affect the driving safety, will the tire hair increase the tire noise? At this point, it can be completely denied. Because the problem of tire noise is mainly caused by the tire touching the ground and rotating at high speed when the vehicle is driving at high speed, the pattern on the tire surface makes the air squeezed and then released, and this continuous squeezing and releasing process forms tire noise. From this point of view, the fetal hair on the tire will not increase the tire noise problem, and when the wheel runs at high speed, the fetal hair can be ignored, so it is not necessary to shave it off as fetal hair.

Check the tires you use carefully. When checking tires, it is necessary to check tires including spare tires and check tire pressure. Check for bumps, cracks, cuts, nails and abnormal tread wear. Using damaged tires may cause tire damage. Driving a vehicle on a road with potholes, rocks or other objects may damage the tires and make the vehicle inaccurate. Therefore, when driving on such a road, you must drive slowly and carefully. After passing these sections, check whether the tires are damaged, such as cuts, bulges, nails, abnormal tread wear, etc.

Always measure tire pressure. Tire pressure is a very important indicator in the process of tire use. It is necessary to ensure that the tire pressure is consistent with the pressure required by the manufacturer. Otherwise, whether the tire pressure is high or low, it will bring great damage to the tire life. If the tire pressure is too high, the pattern in the center of the tire tread will be more worn than the pattern on both sides. Moreover, when the tire pressure is too high, the contact area between the tire and the ground is small, and the car accelerates. Some tires that leave the ground and return to the ground will be deformed due to acceleration, thus showing fluctuations. When driving in this way, not only the tire resistance increases, which affects the acceleration performance of the car, but also the steering wheel vibrates and deviates.
