These protrusions covering the tires are usually found in large wheeled vehicles such as trucks and tractors. Their length is 1-1.5 cm. Although it is thought to show the amount of wear, it has nothing to do with it.
It’s also found in bicycle tires, and we used to really enjoy ripping them off when we were little. As for what these little extensions, about which there are many claims, do…
These tiny pieces are formed by holes in the metal molds that give the tires their shape. So why do these holes exist?
- If you look carefully at the mold visible in the photo, you can see the holes in question.
During production, heat and pressure are applied to ensure that the liquid rubber forming the tire takes shape. With the effect of this, air bubbles form between the tire and the mold, which expands and fills the mold.
Thin channels must be left to allow these bubbles to escape. Tire pieces leaking from these channels turn into thin extensions in question.
So is there any harm in removing them?
These rubber pieces do not have any functional purpose. The tracks only indicate that the tire is new. Breaking them will not damage the tires, but it is not recommended to use tools such as scissors or knives to cut them.
In fact, not all tires have these extensions.
The reason for this is the use of a system that destroys these extensions during the production phase in some tire factories. Since this system burns some pockets, it may not be preferred by companies.
