Tire hairs, also known as hairs, have a specific function in the manufacturing process; find out more

If you’ve ever bought new tires, you may have noticed small rubber “hairs” on their rims. At first glance, these may seem like a quality indicator or a functional feature, but they’re actually simpler than they seem.

Let’s explore what these tire hairs actually are, why they’re there, and if there’s anything you need to do about them.

What are tire hairs?

Tire hairs, technically called ventilation vents, are small pieces of rubber that appear as a result of the manufacturing process. They have no practical function in the vehicle's performance.

Contrary to what many believe, they do not help with traction, sound control or tire durability.

Those "by” appear because tires are made by injection molding. During manufacturing, the mold needs to have small details to allow air to escape while the liquid rubber fills all the cavities.

These holes, called vents, ensure that the mold is filled completely, leaving no empty spaces. Excess rubber that escapes through the vents forms the small “hairs” that we see in the final product.

Should I be worried about them?

No! These hairs do not indicate the quality or condition of the tire. If you have just changed your tires and noticed them, you can rest assured. They do not affect the performance of the vehicle or pose any kind of problem. If you want to remove them, you can cut them off, but this is purely a matter of aesthetics.

In fact, for those who don't have the patience to deal with this, the good news is that these hairs disappear with use. Constant friction with the road causes them to wear down naturally over time.

What really matters when it comes to taking care of your tires?

While tire hairs are nothing to worry about, there are other signs you should look out for to ensure your safety and prolong the life of your tires:

  • Tread depth: It is essential to check that the depth is within the recommended limits, ensuring good adhesion and safety.
  • Irregular wear: It could indicate problems such as misalignment or compromised suspension.
  • Cracks or cuts: may be signs of deviations and represent risks.
  • Tire pressure: Maintaining correct calibration is essential for vehicle stability and fuel economy.

Tire hairs are an interesting but completely harmless curiosity. They’re just a visible reminder of the sophisticated manufacturing process behind something we use every day and don’t always take for granted. When caring for your car’s tires, focus on what really matters: regular maintenance, alignment, and safety. After all, your tires are literally the point of contact between you and the road – and that deserves attention!
