If you have ever looked closely at the tires on your car, you have probably seen little hairs sticking out of the black rubber. Are they there for any safety reasons? Those little bits are one of the strange car features some people may stop to think about.
Located on the vertical part of the tire, these curious little rubber hairs are known as " vent spews (轮胎毛刺)" . They are crucial in the tire-making process. As the tread pattern mold (胎面花纹模具) is pressed into the tire' s rubber, the extra rubber requires a way to escape the mold.
Curiously, there' s no set number of hairs each tire will have. But the presence of tire hairs is universal. They are nothing more than remnants (残余部分) of the complex process that makes strong and durable tires.
Because they are found on the part of the tire rubber that doesn' t hit the road, and they have no impact on how well your tire grips(抓牢) the pavement in rainy weather. These rubber hairs also don' t have any impact on road noise or why your tires squeak when you' re driving. They are merely evidence of the new tire' s arrival in the world.
Tire hairs are naturally worn away during normal driving, and the presence or absence of these hairs doesn' t determine if a tire is safe. There is one instance, however, where the lack of tire hairs can matter. As a responsible car owner, you should monitor the health of your tires regularly.
A. Why do tires have hairs?
B. Tire hairs don' t have any effect on safe driving.
C. Are there any other interesting facts about cars?
D. They look funny, yet every new car tire has them.
E. It could be a sign that tires are worn, old and need to be replaced.
F. The exact number varies based on the design and size of the tires.
G. Because tiny-size escape vents are created throughout each mold, little tire hairs are born.
