Why are there some rubber spines next to the new tires of the bike?

The same is true for most of the new tires in cars.

These little spines don't have much of an app. When making tires, soft rubber is injected into the mold and pressed, often the injection amount is slightly larger than the practical amount (to ensure that the amount is sufficient), and the excess rubber or gas is squeezed into the space of the small holes prepared in advance, leaving many small punctures after hardening.

It is a burr and will not affect the quality of the tire.

The reason for the occurrence of burrs is that when the raw rubber of the tire is heated, the rubber expands, and the excess rubber runs out of the small holes of the mold, which is basically the form of new tires.

It is a burr, some manufacturers will remove it, some do not, but it does not affect the quality of the tire.

Burrs are caused by the expansion of raw rubber when the raw rubber is heated, and the excess rubber runs out of the small holes in the mold, which is basically the case with new tires.

That's called tire hair.

Tires have a certain fluidity before vulcanization, and the tires on the market are formed by heating and pressurizing in the mold, and the pores are formed in order to discharge the air inside the small holes on the abrasives when pressurized, and the higher the level of the abrasive design, the finer and less hairs will be. Of course, the hair on the tread has generally been cut off before leaving the factory, only some small hairs on the sidewall. You can cut it off, or you can leave it alone.

Basically nothing to do with use.

It's really hard to find the answer, and I've learned it.

What a thorn, I didn't make it clear. Non-slip bar.

It is useless for the tires themselves, which are formed in the mold when the tires are built, and the hairs are located.

It is the feeding hole of the mold, which is used to pour rubber.

It can be used to judge whether the tire is a new tire, the tire hair is easy to be rubbed off during use, the tire with tire hair is a new tire or a quasi-new tire, and the tire without tire hair is an old tire.

It is not very useful, mainly to judge the newness of the tires.

Commonly known as fetal hair, it is useless, only new tires have, and it will fall off when rubbed on the ground, so it is mainly used to judge whether it is a new tire.

1. It's useless.

2. The reason for the production of tire hair is that the tire is a rubber product. At the time of molding, a high-temperature vulcanization process is used. There are many vents in the mold, and the fetal hair is formed after the liquid rubber runs into the vents.

Those are tire hairs, which are produced by abrasives during the production of tires, and there is no problem with normal use.

It's useless, it's just the vent when casting.

In fact, this is used to determine the degree of wear.

As long as you are careful, you will also find that next to the tires of the newly bought large trucks, the old drivers will drop a few small tapes, which are actually the same as this. You can protect the tires during driving to avoid some small things, such as stones, from hitting the tires directly.

The rubber vulcanized residual rubber tank avoids the deep groove with less rubber and breath-holding settings.

Making tires can be described as a production process, and I think many of them have been found to be large.

Most of the tires will have erected "tire hair" on the shoulder, so I believe that some people will ask, why do tires appear in the process of making "tire hair"? Is tire hair a must? Why do some tires not have "hair"?

Below, Xiaobang will take you to find the answer from the tire manufacturing process.

In fact, in the process of using tires, tire hair is not of much use, and it can even be said that there is no need to exist at all, so why is there still tire hair? How did it come to be?

In the production process of tires, there are many vents in the mold, and the liquid rubber enters the vents to cool down and forms tire hairs. For example, the reason why Michelin tires do not have tire hair is because they have trimmed the tire hair, which has made the tire look more beautiful.

Now, in order to make the appearance of the tires produced by many tire manufacturers more beautiful, they have trimmed the tire hair, the tire hair is not much use for the tire itself, and it doesn't matter if it is trimmed, so when consumers buy tires, they don't need to care whether they have tire hair, just pay attention to the performance and formula structure of the tire itself.

Two methods; Method 1: Expose to the sun. Method 2: Paint the tires with alcohol. Principle; 1. Drying in the sun can make the rubber composition stable and no longer emit smell. 2. Alcohol is volatile and can be mixed with rubber gas to take away rubber odor.

Yes, who said no, but aren't car tires also bad, bicycle vacuum tires are also available, but generally sports bicycles are used more, roads and mountains, if you are a civilian, you can accept a tire? Road and mountain, **Can you take it? There are things, but you are not the Tao or you don't have there!
