Automobile basic knowledge (13) how to identify retreaded tires?


汽车基础知识(十三)如何识别翻新胎?

Hello everyone, see you again

汽车基础知识(十三)如何识别翻新胎?

In the column of the previous issue

We mainly talked about the types and models of tires

Then I saw someone in the comment area asking: Where is the production date of the tire

汽车基础知识(十三)如何识别翻新胎?

The cardholder who asked this question must be an old driver

Finding the production date of the tires will not only help you avoid buying tires from stock

It also avoids buying something even worse – retreaded tires

So in this issue, let's talk about the problem of retreaded tires

I'm sure you're just like me

Determine whether a tire can continue on the road

It mainly depends on the depth of the pattern

As a result, many profiteers began to buy back used tires

Engrave the pattern a little deeper

Then it continues to flow into the market and sell for money

Cardholders who read my last article should know

There is actually a lot of padding underneath the crown of the tire

They play the role of supporting the tires

For a tire that has been scrapped

The rubber pattern on it is almost worn out

Carving the pattern further down is likely to damage the filling

Tires can become very fragile

It would be very dangerous to put on such tires on the road

But on the other hand

A tire that is normally worn and scrapped

The internal padding (cushioning, ply, etc.) is not damaged

It's just that the rubber on the outside is thin

If you think of it as a completely useless scrap

It's a shame indeed

So what should be done?

"

Don't throw away the worn old tires, dip them in egg liquid, wrap them in breadcrumbs, and fry them until they are golden brown on both sides.

"

Hahaha just kidding

Of course you can't do it that way

For a regular tire retreading plant

They will first be on the tires that will be subjected

examine

Re-rounding

polished

Scraping

mend

Thickened

Embossed

The process is very comprehensive and takes a lot of time

Do this out of the retreaded tire

Although the service life is not as good as new tires

But the security is still guaranteed

Nowadays many regular tire manufacturers

For example, Michelin, Bridgestone, Goodyear, etc

Both have retreaded tire business

If you want to buy this retreaded tire

It is still recommended that you buy it from the official channels of big brands

Their retreaded tires will meet a certain standard

And can enjoy the original factory warranty service

The quality produced by private workshops is relatively unassuming

Having said that

In the end, it still comes down to how to identify inferior retreaded tires

汽车基础知识(十三)如何识别翻新胎?

First of all, the first method, which is mentioned at the beginning, is to find the production date

On the side of the tire

You can find four digits like this

The last two digits indicate the year

The first two indicate the weeks of the year

For example, 0610 in the image above

Represents the 6th week of 2010

Other than that

Everybody knows that

There will be an indicator below the tire pattern to indicate the degree of wear

If the tire is retreaded using the first method above

Then this indicator will definitely be gone

The pattern is deep but the indicator is not visible

That's definitely a retreaded tire

And finally

It's judged by the color

Many retreaded tire manufacturers will wax their tires

Makes tires look shiny

If you touch this type of tire with your hand, you can see that fingerprints are left on it

This is not the case with normal new tires

Furthermore, the tire which I retreaded by the first method above

The pattern will also be uneven

Very poor workmanship

At this time, you need to keep your eyes open and distinguish well

Well, that's all for the retreaded tires

Everyone is welcome to discuss the precautions for buying tires in the comment area
