Why Tyres Have Tiny Rubber Hairs? Useless Or Crucial To Mileage - Purpose Explained
Tiny Rubber Hairs On Tyres: Have you ever noticed the tiny rubber hairs on new tyres? You probably have, as almost all new tyres have small rubber protrusions. However, many people don’t know why they are there. Are they useless, or do they serve a purpose? In this article, you will learn the reason behind rubber hairs on tyres, known as vent spews.
Manufacturing process
)
These are formed during manufacturing and are also called sprue nubs, tyre nibs, gate marks, or nippers. Many people assume they play a role in improving mileage or enhancing tyre performance, but this is a misconception.
vent spews
So, are vent spews useless? To understand this, let's look at how tyres are made. During manufacturing, raw rubber is placed into a molding machine, and air pressure shapes it into a tyre.
Tiny hairs
The mold has small vent holes that let air escape. Along with the air, small amounts of rubber also squeeze out, creating these tiny hairs.
Durability
Therefore, it can be said that the vent spews are the byproduct of the correctly manufactured tyre. They help to make tyres durable.
No functional role
Vent spews serve no functional role beyond the production stage. They don't affect the tyre's performance by any means.
