The car was bought for 1 year and 3 months, less than 20,000 kilometers, is it a quality problem for

Hello, judging by the use of your tires, it should be normal. None of your tires have cracks on the sides, indicating that you are driving on a poor road surface, or that there is something corrosive on the road you are driving on. Of course, it's not too clear to see.

The general tire warranty period is one year, you can go to the 4S shop to reflect this situation and let the tire manufacturer identify it and give you an appraisal report, I hope I can help you, thank you.

The quality of car tires is a bulging tire, and the ** you provide is obviously a scar caused by external forces, which is not a quality problem.

The most common thing about the aging of tire rubber is that the surface of the tire is cracked and there are many small cracks, which is called tire cracking. Because tire rubber requires a certain hardness, there is a process called vulcanization in manufacturing. Vulcanized rubber increases its hardness, but it deteriorates over time.

Therefore, the general service life of tires is about 3 years.

So the simple point is because tires need enough hardness, but everyone knows that the characteristic of rubber is soft, so when producing tires, it is necessary to improve the hardness of tires through a process, which is called vulcanization. It is bound to improve the hardness of the tire, but after a long period of use, the tire will deteriorate, and this phenomenon is called "cracking".

The reason why tires need to be replaced after six years is mainly because the natural aging period of the natural rubber used in the manufacture of tires is 6 years, and after 6 years, a large number of cracks will gradually appear in the tires, or the previous small fine lines will gradually become a piece. However, a lot of cracks does not mean that a puncture will occur, and it can still be used depending on the situation. Generally speaking, in the case of urban road surface and low driving speed, cracks will not affect driving safety.

Then, the basis for replacing tires is mainly as follows.

First of all, there are indeed too many cracks and they appear on the sidewall. The parts of the tire can be mainly divided into: tread, shoulder and sidewall. Of the three, the tread is the strongest, while the sidewall is the weakest.

So, if there are a lot of cracks on the sidewall, then the weakest part of your tire is badly damaged, and then it really needs to be replaced. Otherwise, when the tire pressure increases in summer or when the tire pressure increases, the sidewall is easy to bulge, which affects driving safety.

Secondly. Irregular cracks. Small cracks on tires are usually evenly distributed, but if several cracks are on one side or section of the tread, it is not only necessary to replace the tire as soon as possible, but also to check the parts of the wheel attachment.

Tire wear can be a reflection of a failure in the vehicle's driving system, just as a person's shoe soles are abnormally worn, and that person's legs, feet, or walking style must also be problematic. Further, even if you change a pair of shoes, if your physical problems do not change, the new shoes will not last long and will break. The same goes for tires.

The abnormal wear of tires can be divided into: 1. Tread wavy wear, indicating that the dynamic balance of the wheel hub and the transmission shaft is abnormal, and it is necessary to calibrate the dynamic balance together with the wheel hub after the new tire is installed. 2. Abnormal wear on the inside of the tire means that the camber angle of the front wheel is too small or the toe value of the front wheel is too small, and the four-wheel alignment needs to be re-performed.

Abnormal wear on the outside of the tire, on the contrary, indicates that the camber of the front wheel is too large or the toe value of the front wheel is too large. 3. The tire tread is extremely worn, indicating that the tire pressure is too high, and the tire pressure should be adjusted in time.

Finally, whether the tire crack increases needs to be replaced or not, and the specific problem is subdivided, but it can be determined that the crack is increased, and it is necessary to ensure that the vehicle is inspected daily before use in the future. Keep a close eye on the tyre's pressure, tread depth and vehicle height.

I think of course it is needed, because such tires affect safe driving, and it is best to replace the tires every two years.

Of course, because there is a risk of a puncture at any time, and it is necessary to replace it with a new tire immediately for safety reasons.

I feel the need for it, because these tires affect insurance driving, and the tires are changed every two years.

The car tires have been around for 6 years, and the wear is not bad, but can they still run at high speed with many cracks? How to say it, in fact, according to the degree of damage, then it is possible to run high-speed, but from the degree of safety, it is not possible to run high-speed, because the speed of the vehicle on the high-speed is very fast, like this hand-yard wear and tear of such a serious tire, at such a speed on the high-speed driving, then what problems will occur if it is not even, so it is better not to see, tell because the driving speed on the high-speed is very fast, then once in the state of high-speed driving, Once there is an accident with this tire, then the whole car will have an accident, which will cause great damage to our safety, so this tire with such severe wear cannot run at high speed. <>

Like this wheel, which tire is finished, it has been 6 years, the wear is not bad, but there are a lot of cracks, and there is no problem in driving on the normal highway of my Peizen, but it can't run at high speed, why do you say that? Because our normal highway speed is not very fast, but at high speed, then our vehicle is very fast, then this tire, it has a lot of cracks, maybe under high-speed driving, then once the tire bursts, then it will cause a huge ** for the personnel on the car, not only that, but also a danger for other vehicles on the highway, so this tire crack so many can not run at high speed, Because it is a very dangerous behavior. <>

In our normal highway driving, this tire is no problem, but at high speed is not necessarily, because the speed of high-speed driving is very fast, before high-speed driving, then no one can guarantee that the tire can still work normally Once the tire bursts, the whole vehicle will suffer a serious accident, when the accident is not only one car, even other vehicles on the highway will suffer from the impact of the accident, so the harm is not experienced, This happens to people who are just a car and even a lot of people. <>

In general, if the tire is so badly worn, then we should not run at high speed, because the tire with so many cracks will be prone to accidents at high speed, and the number of people affected will not be a car, and many people will cause major accidents because of an accident in a car.

Not recommended, because the situation of tires is very prone to accidents, and it is possible to crash and die at high speeds.

I don't think so, because the strength of this kind of tire is already very low, and it is easy to get a puncture when running at high speeds.

I think definitely not, because this tire is already on the verge of obsolescence.

Cracks, stickiness, hardening, softening, chalking, discoloration, and mildew are a manifestation of the aging of all rubber products, and automobile tires are no exception. So to what extent do tires need to be replaced?

First of all, starting from the material of the tire, the main body of the tire is rubber, and the longest storage and anti-aging time of rubber from natural latex to ethylene propylene and nitrile will not exceed 10 years, and the average service life of various rubber products in use is 3-5 years.

Tires carrying the weight of the vehicle are often responsible for slowing down the cushioning effect, and they also have to resist corrosive rain and cleaning fluids from car washes. Therefore, the aging of tires will be greatly reduced.

Generally speaking, the life of tire wear is 3-50,000 kilometers, if the tire has not reached the wear limit and mileage, but the service life of the tire reaches 5 years or a large number of cracks on the side, it is necessary to replace the tire.

Tires are the feet of the car, and the car wants to drive safely and work stably, which is closely related to the tire. Although there are many types of tires, but mainly in size, appearance and structure differences, the basic materials are rubber, and rubber materials are very good in terms of plastic elasticity and other properties, but a very important situation is easy to age, compared with metal parts, the life is relatively short.

Many car owners in the inspection of their vehicles, they found some abnormalities on the tires, such as obvious cracks on the tires, and the number is very large, see this situation, many owners think that the tires may burst, or will be leaking, consider to replace the new, so crack tires need to be replaced? The auto mechanic tells you the answer.

There are actually a variety of cracks on the car, the most common is actually a small crack, although the number of small cracks is very large, but it is very shallow, so the impact on the tire is not large, the cause of the appearance of small cracks has aging factors, but more is not well maintained, especially often driving in the water or muddy road, or the tire is in direct contact with water, and then the car is parked in the sun, the tire itself is black, the heat absorption is very fast, the temperature rises quickly, Under the effect of thermal expansion and cold contraction, many cracks will naturally occur.

Once these small cracks appear, the aging of the tire will be intensified, because the small cracks will remain in the moisture, and the cracks will become wider and deeper due to frequent cold shrinkage and heat barriers. If the crack appears at the bottom of the tire, that is, the place where it is in contact with the ground, because the pattern is also very thick, there is no need to replace it at this time, and it will not have much impact on the tire, if it appears on the side wall of the tire, it must be replaced in time, the tire wall is the weakest place, and it is easy to have a puncture accident when the tire pressure increases, or when it encounters spikes.

For very deep cracks, then whether it appears on the sidewall or the bottom of the tire, it needs to be replaced, because the tire itself is divided into multiple layers, the outermost layer is mainly to play a protective role, a deep crack will directly lead to the outer layer to lose the ability to protect, the inner primer, belt layer, sealing layer are very thin structure, once into the sharp things, it will bring great damage to the tire, there is a possibility of a puncture accident, when driving at high speed, it will be very dangerous.

Tire replacement also needs to take into account the amount of wear, now the tires are integrally formed, in the production of wear reference, in the middle of the tire pattern, the grip of the tire and the pattern has a close relationship, whether the brake can be braked, the main thing is to look at the friction between the pattern and the ground, if the pattern is seriously worn, the wear marker has been about to enter the wear state, then the tire also needs to be replaced.

Less than two years after the new tires were replaced, the mileage was less than 20,000 kilometers, and there were such serious aging cracks, no matter how neglected the maintenance and the road environment was, it would not lead to this state. Most likely, it was a retreaded tire.

There are potential safety hazards in this aging tire, air leakage is small during driving, once the tire bursts, any old driver can not control it, it is recommended to replace it as soon as possible, life safety first.

The normal service life of tires is about 50,000 kilometers, and of course, there are tires that can be driven for more than 100,000 kilometers. The same tires, the same driving environment, the front wheel is not seriously worn, but the rear wheel is seriously worn, even to the extent that it needs to be replaced, which shows that there is no problem with the quality of the tire, so what is the problem? The most likely reason for this is the rear wheel toe.

The parameter is incorrect.

Wheel alignment of tires.

Including not only the alignment of the front wheels, but also the alignment of the rear wheels, the correct alignment of the rear wheels can not only ensure the stability of the vehicle, but also ensure that the vehicle has good handling, and at the same time can also reduce the wear and tear of the tires.

Rear wheel alignment includes rear wheel camber, rear wheel toe-in and rear-wheel drive force action line. Generally, the rear wheel does not need to adjust the rear wheel parameters if it is non-independent suspension, and the rear wheel parameters need to be adjusted if the rear wheel is independent suspension.

Rear wheel camber: The rear wheel camber is not a fixed value, and its parameters will change constantly depending on the road conditions. The purpose of adjusting the camber angle of the rear wheels is to distribute the dynamic load center between the wheels and the ground, thereby reducing the wear and tear of the parts and tires.

Rear wheel toe-in: Rear wheel toe-in and front wheel toe-in function the same, and the most likely possibility of serious tire wear is caused by incorrect rear-wheel toe-in parameters of the rear wheel.

The rear-wheel driving wheel line is to keep the two rear wheels parallel to the whole vehicle, and the driving wheel line is perpendicular to the rear axle and coincides with the longitudinal axis. The function of the drive line of action is to prevent the vehicle from deflecting.

After driving 20,000 kilometers of tires, the rear wheel is seriously worn, most of which is caused by the incorrect toe-in parameters of the rear wheel, and it is recommended that the owner adjust the four-wheel alignment of the vehicle as soon as possible to prevent the continuation of similar situations.

Tires wear out quickly, first of all, it depends on how many kilometers you have driven in the past two years, if you have driven 3-40,000 kilometers, it is normal! Secondly, look at the road surface, often bad roads or national highways cost tires! Third, depending on how brave you are driving, you often throttle hard, brake sharply, and the speed is fast, just on the ordinary road section, not to say the high-speed above, so that the tires must wear out quickly!

If you rule out the above possibilities, then go to the maintenance point to check whether you need to do four-wheel alignment, and it won't cost a few hundred dollars!

If the quality of the tire is fast, it is understandable, but you are too fast, do a positioning to see if it is a positioning problem.
