How deep is the side scratch of a car tire to replace the tire?

If the side of the tire is scratched 4 mm deep, it is recommended to replace the tire.

Because the thickness of the rubber on the side of the tire is often no more than 1 cm. In addition, if the scratch is not serious and does not damage the cord layer of the tire, it can be used even if it exceeds 4 mm. However, if the cord layer inside the sidewall has been injured, even if it is no more than 4 mm, the tire needs to be replaced, otherwise there is a risk of a puncture.

Notes:

In fact, there is no fixed number on how deep it is allowed, after all, different brands have different requirements for the thickness of the side of the tire. If the scratch is not serious and does not damage the cord layer of the tire, there is no problem in continuing to use it. Of course, if you are still not at ease, we can go directly to the auto repair shop to fill in the missing part and rebalance it.

However, if the cord layer inside the sidewall has been injured, it has to be mentioned separately, and basically it cannot be continued, otherwise there will be certain safety hazards.

In general, the problem of scratches on the side of tires is directly related to driving safety, but don't ignore it.

The side of the tire is scratched by 4 mm and must be replaced.

First of all, the thickness of the rubber on the side of the tire is often no more than 1 cm. Once this part is damaged, the probability of injuring the meridian layer is very large, once the meridian layer is damaged, the structure of the entire tire can not be guaranteed, and the tire may burst at any time.

It should be noted that the most extreme side scratches cannot be as deep as 4 mm. Generally, a visible opening is likely to exceed 4 mm. At this time, change the tire quickly, otherwise it is very easy to have a puncture.

If you can see a scratch on the side of the tire with the naked eye, one thing is for sure, the scratch is not shallow, and may even endanger the structure of the tire.

Therefore, you can touch the scratch first, and you can feel many things with your hands, including how the scratch came about, whether it was caused by a sharp object, or some kind of blunt object. Scratches from blunt objects can create an uneven surface, and some debris such as broken stones can be felt inside the scratches.

This can be touched, if it is injured by a sharp weapon, it is likely to be injured by some sharp roadside debris when driving, this kind of injury is generally small, but it will be cut deeply, and it is likely to have damaged the meridian structure in the tire. If the scratch is not deep, you can ignore it or repair the tire. If the scratch is deep, it is still recommended to replace it.

How deep are the side scratches of the car tires, and the need to replace the tires is based on the normal use of the tires, as long as there is no puncture, the tires do not need to be replaced. The general process starts from discovering the problem and raising the problem, and after discovering the problem, make assumptions about the answer to the problem according to their existing knowledge and life experience Design the first plan, including the selection of materials, design methods and steps, etc. After reaching a conclusion, it is also necessary to reflect on the whole process of the general methodological steps of the experiment: asking questions, making hypotheses, making plans, implementing plans, drawing conclusions, expressing and communicating

The most commonly used methods in science include observation method, experimental method, investigation method and data analysis method

Observation is a basic method of science Scientific observation can be made directly with the naked eye, with the help of magnifying glasses, microscopes and other instruments, or with the use of cameras, video recorders, video cameras and other tools, and sometimes it is also necessary to measure Scientific observation should have a clear purpose; Observations should be comprehensive, meticulous, and realistic, and recorded in a timely manner; Be planned and patient; Think positively and record in a timely manner; To exchange views and discuss The design of the experimental protocol should be carried out closely around the questions and hypotheses raised When studying the influence of one condition on the research object, the experiment carried out under the same conditions except for the different conditions is called a controlled experiment General steps: find and ask questions; gather information related to the issue; make assumptions; design of experimental protocols; Conduct experiments and record them; analysis of experimental phenomena; Conclusion Investigation is one of the common methods of science When investigating, we must first clarify the purpose of the investigation and the object of the investigation, and formulate a reasonable investigation plan During the investigation process, sometimes because the scope of the investigation is very large, it is necessary to select a part of the survey objects as samples During the investigation process, it is necessary to record truthfully The results of the investigation should be sorted out and analyzed, and sometimes the statistical methods should be used to collect and analyze data is also one of the common methods of science There are many ways to collect information Go to the library to consult books and newspapers, and visit relevant people, The form of information includes text, **, data, and audio-visual data, etc., and the information obtained should be sorted out and analyzed, and answers should be found from it.

If the side of the car tire is scratched about 4mm, the tire should be replaced. Hope.

Hello! If the side of the car tire is scratched by steel wire or nylon thread, the tire must be replaced! Of course, for safety reasons, it is recommended to replace it if the scratches are serious.

How deep the side of the tire is scratched needs to be replaced.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

The rubber compound on the sidewall is very thin, generally about 3-4mm, unless it is an airtight tire with thick sidewall rubber.

Normally, if there is a scratch on the sidewall, the owner needs to pay attention to it, because even if the crack is not deep, the crack may extend as the sidewall continues to curl.

The quality and stability of the "three major parts" of the car are related to our driving safety, so we must maintain them on time, but many people ignore the importance of tires. So let's take a look at what happens to the tires and remind us that it's time to change the tires?

Due to the different thickness of the sidewall of different brands of tires, the scratches are not serious, and the cord layer is not damaged, that is to say, the structure of the tire has not been damaged due to scratches, and there is no air leakage, which can not be repaired or replaced.

However, for the sake of safety, it is better to go to a regular repair shop to inspect and do a dynamic balance test on the wheel with scratches on the side. For injuries to the fracture of the cord layer, the tire is basically sentenced to death, there is no excessive repair value, and the reluctance to repair will only increase the potential safety hazards.

The brand, model, and use of the tire are different, and the thickness of the tire is also different, so it is impossible to say how deep the side scratch is allowed, it depends on the actual situation. Generally speaking, the rubber on the side of the tire is very thin, which makes it easy to puncture from the damaged area and cannot be repaired.

Tires that cannot be repaired: the sidewall has been severely damaged, the diameter of the hole penetrated by the crown is more than 6 mm, the bead is damaged or deformed, the rubber is corroded by chemicals, the tire is bulging, and the tire is damaged by lack of air.

The specific analysis details of the side scratch of the car tire replacement tire are as follows:

1. If the side of the tire is scratched to a depth of 4 mm, the tire should be replaced, otherwise there is a risk of puncture;

2. The cord layer is not damaged, even if the scratch depth exceeds 4 mm, it can be used continuously;

3. If the cord layer inside the sidewall is less than 4 mm, it should also be replaced immediately, because the risk of puncture is very high.

Use a knife or screwdriver to probe the wound to see if it is damaged to the cloth curtain (copy to see if there is any exposed cord), if there is no big problem, you can change to the rear wheel to use, if the exposed cord is best to find a professional master to repair (the sidewall is generally scratched very well repaired, the wound ZD grinding to the cord cleaned, coated with high temperature vulcanizing agent, and then filled with raw rubber vulcanizer vulcanized for half an hour).

Need to see if the mouth has been damaged or injured the cord fabric material of the inner hundreds, if the sidewall has been damaged, we do not recommend repairing it, if the mouth has not hurt the cord cloth material, then you can also ask to continue to use, but you need to regularly check whether the wound is wide, whether the cord is damaged, if so, please replace the new tire version in time. If it is clear that there is a leak or bulge, it is not recommended to continue the use of tires.

The side of the tire is scratched more than 1mm deep to be replaced:

1. Most of the one mm (mm) will not hurt the internal cord fabric material, and can be used continuously;

2. You can judge whether the tire needs to be replaced according to the following methods, if the wheel tire is aging (for example: there are countless small cracks in the tread pattern, groove bottom or sidewall, which are about to hurt the carcass), you need to replace the tire immediately, no matter how long the tire is used and how much it is worn;

3. If the depth of the groove left in the tire pattern is up to or below millimeters) (there is an indication mark indicating the depth in the longitudinal straight groove of the tire tread), the tire must be replaced, because the drainage capacity of the tire has been greatly reduced, the vehicle will be more dangerous to drive in wetland.

The tire includes the outer layer of rubber and the inner layer of steel cord fabric, and the more important part is the steel cord fabric. Due to the different types of tires and the inconsistency of wear, the depth of the scratches on the front of the tires needs to be replaced according to the specific situation of the tires being scratched, as long as the wire cord is scratched, it must be replaced; If you only see the wire cord, it is recommended to change it for driving safety; In addition, if the steel cord fabric is broken, there is a possibility of a puncture, and it is also recommended to replace it. If the front of the tire is scratched in a shallow depth, only a small piece of skin on the tread, and most of the driving environment is in the urban area, the tire can be repaired and does not need to be replaced.

However, if you often run at high speeds, it is recommended that you need to change no matter how deep the stroke is, because in the case of a very fast speed, it is easy to burst the tire with a little scratch, and there is a great safety hazard. The solution to the front of the tire being scratched:

1. Just a small piece does not affect the use, but you should pay attention to check whether there will be cracks near the scraping place, accelerate wear or bulge, etc., and replace the tire in time if there is;

2. If the front tire is damaged, replace it with the rear tire, which will be relatively safer if a puncture occurs;

3. It is best to go to a professional tire maintenance point to be tested by professional maintenance personnel and listen to the suggestions of professionals.

4. The tire can be replaced as a spare tire for emergency use.

5. Tire scratches can not run at high speed, and it is easy to burst after a collision in the case of fast speed;

6. It can not be heavy-loaded, and the load-bearing capacity of the tire is reduced after scraping off a small piece, and the load is easy to burst; The above is only for the situation that the front of the tire is scratched, because the sidewall of the tire is much thinner than the front, so it is best to replace it in time when the sidewall is scratched. In addition, the sidewall needs to bear the load, and it has been in a state of alternating deformation recovery in the process of work, so that it is easy to reach the fatigue limit of the tire, which leads to a puncture.

Hello friends, this ** situation is recommended to be replaced.

<> "Tires are one of the most important accessories on the vehicle, and when you use the vehicle, you find that there are obvious scratches on the side of the tires of the vehicle, which makes the owner very troubled. So how deep is the scratch on the side of a car tire to replace the tire?

In fact, no matter how deep the side of the car tire is scratched, as long as the side of the tire is scratched, the owner needs to replace the vehicle with a new tire in time.

Because the weakest position of the tire is its side, the side is not as thick as the bottom of the front, and there is no high strength of the belt protection; And the vehicle tires need to bear most of the weight of the body, if the side of the tire is scratched, the tire will have a higher risk of bulging, in serious cases, there may be a risk of puncture, seriously affecting the driving safety of the owner.

Therefore, once there is a scratch on the side, it must be taken seriously. In addition, it is best for car owners to develop the habit of checking the side of the tire every month, because when the car is usually parked on the side, even if there is friction on the side of the tire, it is difficult to detect, so it is necessary to check the tire regularly, and there are no scratches, aging and nails on the appearance of the tire.

It is advisable to replace the tires in a timely manner, no matter how deep the side scrapes. If the tire is scratched, check to see if the safety line is missing. If there is a missing wire, it must be replaced.

If there is no missing line, you can drive in the city. Generally speaking, the problem of abrasion on the side of the tire is directly related to driving safety, so don't ignore it. 1.

If the sidewall of a tire is scratched, be sure to replace the tire as soon as possible to avoid the risk of punctures at high speeds. 2.If the contact surface is damaged by more than 4 mm, the tyre must be removed and replaced as soon as possible, and both internal and external repairs are potentially dangerous.

3.It is not advisable to use the car before inspecting and repairing the tires (especially if the front wheels are damaged). 4.

It is recommended to disassemble the tire to check the internal puncture and fully consider the safety. If puncture is not recommended in this position, it needs to be disassembled and replaced. Car tires contain spare tires and must be inspected regularly every month.

When inspecting, check the surface of the tire for cracks or scratches at the same time. It is best to wear gloves and reach to the inside of the tire to check for suspicious marks. As soon as you notice anything suspicious, ask the dealer for a detailed inspection immediately.

Don't be reluctant to throw a defective tire. If you notice abnormal wear on the surface of the tire, it should be considered that there may be a problem with the wheel toe adjustment and that it needs to be repaired. Because the side of the tire is relatively weak, if it is a side abrasion, it is basically irreparable.

If used continuously, there is a risk of puncture, and there is a potential safety hazard. Millions of car purchase subsidies.
