c.The total number of repairs for the entire tire shall not exceed 5 (including past repairs).

5.The distance between the sidewall opening and the toe opening: below, should be greater than 65mm; It should be greater than 80mm (except for engineering tires).

6.It is strictly forbidden to have notches, damages, cracks and other phenomena in the mouth parts of tubeless tires.

2) The repair carcass must meet the following standards:

1.The middle pattern is still more than 4mm.

2.Slight aging cracks are allowed.

It's not written by itself, but I have their company's equipment in my space**, you can take a look.

Friend, if you don't see the hook, I won't go back to your questions on the Internet in the future, from the perspective of doing business, I have lost, but from the perspective of personal cultivation, I should also do the same, but I hope to gain something from my work. Fort Dragon.

Refurbished tires are generally truck tires, first of all, the old tires are required to have no obvious hard injuries, in addition, the brand of the old tires is also very important Good brands are worth retreading, retreaded tires are also called top tires, this kind of tires can not be used in passenger cars, trucks can not be used in guide wheel trailers with more.

Summary. Hello, what kind of tire is it?

Hello, what kind of tire is it?

Yokohama.

Hello, retreaded tires are not recommended, because the current ones are vacuum tires, and there is no risk of a puncture in the retreaded Jianna tires Basically, there are two types of retreaded tires: 1: repair on the original old tires.

Burnish. Polished. From the new carved deep pattern retreading this kind of tire is more from in the very dangerous so it is also illegal in the market more 2:

This kind of retreaded tire technology is relatively high Peel off all the rubber outside the tire In the new rubber is used to get the new rubber up in the vulcanization furnace processing This tire safety factor is much higher than the above Due to the shortage of resources Countries are advocating retreading this kind of tire This market is relatively less The first retreader market is more, the cost Many users unintentionally or intentionally buy this retread tire has been greatly harmed, and the second kind of retread tire is expensive, the market is less, and the user contact is less, so it is not recommended to use Retreaded tires are not recommended to use easy puncture Hello, it is not recommended to use brand new tires, tires are one of the important factors in driving safety, if my answer is helpful to you, please set it to! Thank you! @2019

Now the state also has policy support for retreading old tires. At present, there are 2 types of tire retreading, which are divided into hot and cold retreading, so can the niece of a car tire retread?

First: the road transport has now overrun regulations and rectification, so that the profit of the owner of the truck declined, they in order to save costs, so a lot of retreaded tires to replace new tires, according to the current situation, a new tire can use 2, or even more than 2 retreaded tires, which can greatly save the cost of the car.

Second: because tire rubber is black garbage, even if buried in the ground for decades, or even hundreds of years, it will not rot, so in order to protect the environment of the earth, the state has issued relevant policies on waste tires, which can make them recyclable.

Nowadays, only truck tires can be retreaded.

Because their carcass material is steel wire, it is basically not affected to change the new tread after the surface rubber is aged and worn.

Don't be on the second floor, my factory retreads 50,000 radial tires a year, why can't you retread it? Do you have a bit of a basis for what you say?

After purchasing tire retreading equipment, some small rubber products factories purchase waste automobile tires from waste units, cut off the crown to expose the cord layer, and then re-vulcanize the tire crown through the vulcanization process to produce retreaded tires.

This type of tire has vulcanization marks at the vulcanization joint of the carcass, and the mold marks on the carcass side are uneven and easy to identify. At present, retreaded tires are all bias tires, and radial tires have no precedent for retreading in China. Retreaded tires are only suitable for use in low-speed vehicles and cannot be mounted on motor vehicle steering wheels.

As an important part of the car, the car tire is an important part of the car to bear gravity, traction, braking force, steering force and road reaction force.

In order to better protect the legitimate rights and interests of consumers and protect the safety of personal and property, it is recommended not to use retreaded tires.

Tires have a time of use, and the so-called retreaded tires can not be called real retread, the real retreads are actually the use of good carcasses for tire reconstruction, with strict process control, can save costs and social resources. The reputation of retreaded tires in the society is not good, but some illegal traders make profits for tire counterfeiting or do not have retreading technology and technology, there are great safety hazards, in layman's terms, it is easy to cause traffic accidents, it is recommended not to use.

Car tires are consumables, and if you want to change them, you have to change them in pairs. Those unscrupulous merchants only need to go to the repair point to buy old tires, and they can be made in pairs and twos. The time is fast and the cost is low, so why not?

Then let me show you how this professional retreads tires.

First of all, fix the purchased tires. Then make minor repairs, and then use special white tape to tie up the small repairs.

The second step is to pull up the white tape where it is tied, wait for new dents to appear, and then use a proprietary grinder to polish out the tire lines, as well as the dents, original logos, and symbols.

After polishing some details, a brand new tire is produced.

It is precisely because of the short time required for retreaded tires that many of these tires enter the market every day, but don't worry, I will say three points here to distinguish low-quality retreaded tires.

1. Inferior tires have light grooves and bright colors.

2. The tread of inferior tires is not round between the sidewall. There are signs of bonding. General signs can be cut off by themselves.

3. The tire hair on the tread and sidewall is relatively scarce.

Second-hand retreaded tires are undoubtedly the biggest safety hazard in the process of driving, picking up cheap and replacing new tires, perhaps from then on, every moment on the highway, are burdened with the danger of puncture, loss of control, and crash; It is important to know that more than 70% of highway accidents are due to flat tires.

**As long as the tires are properly maintained, there will be no punctures and other problems during the service cycle, and the cases of punctures on high speed are almost all because of the aging of the tires, abnormal air pressure, and the third point is that there is a problem with the replaced tires.
