There are several scratches on the tire, do you need to replace it?

It's better to replace it, otherwise it won't last long even if it is repaired. It's also a delay.

The car's tires include spare tires and must be checked regularly every month. During the inspection, the surface of the tire should be observed for cracks or scratches. It is best to wear gloves and reach to the inside of the tire to check for suspicious marks.

If you find the slightest suspicious point, you should immediately ask the car dealer to do a detailed inspection. Don't be reluctant to throw away faulty tires. If you find that the surface wear of the tire is abnormal, you should think that there may be a problem with the toe-in adjustment of the wheel and need to be repaired.

The outer edges are worn.

If you look in the direction of travel, there is a large amount of wear on the outside edge of the tire, indicating that the tire is often in a state of insufficient inflation, that is, the pressure is insufficient. If possible, inflate at the "highway" standard, i.e. add another 30,000 pascals to the normal standard. It is important to know that under-inflated tires are very unfavorable for driving in rainy conditions, and the grip will be significantly reduced.

Convex and corrugated wear.

If it is found that the two sides of the tire landing part are convex and worn, and the tire perimeter is also corrugated worn, it means that the shock absorber, bearing and spherical coupling and other parts of the car are seriously worn. It is recommended that you check the suspension system for wear and tear before replacing the tires. Otherwise, even changing the tires won't help.

The surface is evenly worn.

Once the tire pattern has been worn dry, it means that the life of the tire has reached the end of its life and must be replaced. In addition, the pattern also has the effect of draining the water on the road, so it is an important part of maintaining the grip of the car. If the wear has reached the standard depth of the tire pattern (usually mm, or 2 mm for tires with a width greater than 175 mm), it should be replaced.

The center part is worn.

If you notice severe wear on the center area of the tire's landing section, it is a sign that the tire is often overinflated. Be sure to check whether the pressure gauge is accurate, adjust the pressure, and know that you only need to overinflate the tires when driving at high speeds or heavy loads.

Cracks on the side of tires.

This is often caused by poor maintenance, or driving on rocky roads and construction sites, so that hard objects come into contact with the tires, causing damage to the inner layer of the tires under heavy pressure. Immediate action should be taken, and if the repair is not good, the tire should be replaced.

Wear on the inside of the tire.

The inside of the tire is worn, and the outer edge is burr-like. It is common to see some old cars with poor suspension systems, which sink the entire body. This indicates that the tyre is deformed and the symmetry of the two tyres has been compromised.

If possible, it is best to replace all the shock absorbers, spherical couplings and other accessories. However, if the cost is too high, you may want to ask a professional mechanic to adjust the angle between the front axle and the tyre.

1.First of all, you need to see if the opening has damaged the inner cord layer of the tire, if the sidewall has been damaged to the cord layer, it needs to be replaced. If the wound does not hurt the cord layer, it can be used continuously, but it is necessary to check regularly whether the wound has expanded and injured the cord.

If it has expanded to the position of the ply layer after a long time, please replace the tire with a new one in time.

2.If the side of the tire is scratched, it must be replaced at a depth of 4 mm. Because the thickness of the rubber on the side of the tire is often no more than 1 cm. Once this part is damaged, the structure of the entire tire cannot be guaranteed, and the tire may burst at any time.

Why do you need to change a tire after it is scratched? Because the sidewall is the weakest and most stressed place of the whole tire, if it is not replaced in time, it is easy to have a puncture when driving at high speed, which will cause serious traffic accidents.

Hello landlord! No need to change tires! Your position is the rubber protective layer on the front of the tire, and it is also the thickest position of the tire, so it's okay at all.

These injuries don't seem to be deep, but your tires are too badly worn, and the stripes are almost worn out, so it is recommended to replace them if you often run at high speeds.

This injury is not a big problem, and if it is not a long-term high-speed run, it is not recommended to replace it.

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

The tires are very thick, so this hole is so big.

There is nothing wrong with minor scratches on the front of the tire.

If your car is an ordinary car, the car uses radial tires, the structure of radial tires is to form the main body of the tire with more than a dozen layers of metal mesh, and then wrap a layer of rubber on the outside of these metal mesh.

The front of the radial tire (the part that touches the ground) rubber thickness is very thick, but the side due to the limitation of the tire structure, the thickness of the rubber layer will be much thinner, if the sidewall is damaged, the probability of hurting the radial layer (that is, the metal mesh) is very large, once the radial layer is damaged, the structure of the entire tire can not be guaranteed, the tire may burst at any time, especially the faster the speed, the higher the tire pressure, and the gas pressure is easy to cause devastating damage to the metal layer.

Therefore, when your radial tires can be clearly scratched by the naked eye, please replace the spare tire immediately, and then drive your car to a regular repair shop to change the tire.

If you're driving a large passenger or freight vehicle, you're using bias line tires. These tires are not as fragile as radial tires and are resistant to strong rubber and metal layers even if they are visibly scratched. 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.

The side of the tire is the weakest part of the tire, no matter how deep the side of the tire is scratched, for our driving safety, the tire should be replaced in time. But if we're on the road and the tires don't scratch the cord, we can consider continuing the drive for a while. Once it scrapes to the side of the cord, there is a high chance of a tire blowout.

The problem of scratches on the side of tires is directly related to driving safety and cannot be ignored.

The cord layer is meant to play a strong role, so once it is scraped to the side of the cord layer, there is a high chance of a puncture. Secondly, the durability of heat repair is better, and the sidewall of the tire is easy to bend and deform when rolling, which will cause the repair material to fall off in the long run, so when the lateral damage is serious, it should be replaced in time. Many car owners will wonder if there is a wound on the side of the tire that cannot be used or repaired.

Another thing we need to know is that the side of the tire is the weakest part of the tire, unlike the front, the bottom of the tire is strong.

It should also be noted that the scratches on the side of the tire cannot be repaired even if they are not damaged and the cord cloth layer is not repaired, because the tire needs to bear fatigue loads in the process of work, and it must be in a state of constant deformation and retraction, even if the repair is marked as glue, it will fall off for a long time after sticking it to the area. If the side of the tire is scratched, the tire pressure is abnormal, and the tire pressure is too high, which will hurt the wound; Tire pressure that is too low can cause tires to bend and fatigue more, which can lead to flat tires.

Scratches on the side of the tire can not go up to high speed and can not drive for a long time, because both high speed and long-term driving will make the tire temperature high, resulting in high tire pressure, weak tread, more likely to be injured, when the sidewall pressure is too high, it is easy to cause a puncture. Seeing this, I believe everyone knows the severity of the side scratch of the tire, so it is best to check it once a month, because when we stop on the side, even if the side of the tire rubs against the side of the road, it is difficult to detect. Therefore, it is very necessary to regularly check the side of the tire, including the appearance of scratches, aging, etc.

Tires need to be replaced when they are scratched on the side and there are obvious cuts or visible defects; The replacement standard is that the sidewall scratch area is large, the sidewall has obvious defects, the sidewall is seriously worn, and the tire sidewall is dented and there is air leakage.

There has been cracking on the side of the tire, and the cracking is so large that it has affected the driving of the car, so that it can be replaced. The replacement standard is that the scratch has affected the normal operation of the vehicle, and has caused the tire to leak, and the tire pressure has also decreased.

The degree is already very deep, you can see the interior, it must need to be replaced, mainly related to the vehicle, there are some vehicles with relatively large weight, once scratches occur, they must be replaced, there is no clear standard.

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.
