The replacement of car tires mainly depends on mileage and service life. The tires are replaced once every 3-50,000 kilometers of comprehensive road conditions, and the time is 5-8 years.
The tire is rubbed against the ground for a long time, which makes the rubber age, and if the tire still has cracks, it is undoubtedly necessary to take replacement measures, otherwise it is easy to produce potential safety hazards. It is usually recommended that car owners need to be inspected every six months or so after using it for about 5 years, if it can continue to be used, then continue to use, if it is seriously worn and has a poor sense of balance, it must be replaced in time.
Usually there is no clear time regulation for tire dealers, it is recommended that it is best to use it for more than three years, at most about five years, and the tire should be replaced if the mileage is maintained at 3-50,000 kilometers.
Hope it helps, thank you.

Generally, the time when tires need to be replaced is the new model paper. 3 to 50,000 km or 3,5 years. All need to be checked and replaced.
In your case, the new car is only 6000 kilometers away from a little cracked, which is a bit abnormal, is it because of the road conditions or because of his indicators? Of course, this tire is generally not guaranteed.

This crack is not a problem with the quality of the tire, it may be a scratch left by something sharp when you run at high speed or high speed. It's not a big problem, and for the sake of safety, it is recommended to swap the rear tires, after all, the front wheels are steering wheels, and they should be kept intact. It's okay if you don't change it, and you can observe it every 100 kilometers or so, it's a bit too official, anyway, if it's my car tires.
I don't think it's okay at all.

If there is a small crack in a new car tire, you need to determine whether the small crack is on the tread or sidewall of the tire. If on the sidewall, you need to see if the small crack has been damaged or hurt the internal cord fabric material, if the sidewall has been damaged, it is not recommended to repair, if the crack does not hurt the cord material, then you can continue to use, but you need to regularly check whether the wound has expanded, whether the cord has been damaged, if so, please replace the new tire in time.

Seeing the crack in the tire, in order to drive safely and ensure that the vehicle is in normal condition, it is recommended to replace the problematic tire. After all, safety comes first!
-
This is not a natural crack, it should be a scratch of a stone, the problem is not too big, if it is the front wheel, it is best to reverse it with the rear wheel during the safety period.
-
If it is, I'll replace it. For safety!

No, you don't. Tires are made of rubber. As long as it is made of rubber, it will age for a long time, and the tire will harden and break.
Usually, old tires are exposed to sunlight and rain. Although they have good driving habits and little wear and tear, this aging will still occur in about five years. Due to the longer time the spare tire is in the trunk, the aging will be slower.
However, as long as the tires become hard and cracked, they should be replaced over time, let alone at high speeds. As the grip of aging tires becomes less gripping and the braking distance becomes longer, the vehicle's braking is not easy to control. Broken tires are easy to drive at high speeds**, which is a very dangerous thing to do.
Therefore, for safety reasons, we still need to replace the tires as soon as possible.
<>If you want to drive at high speeds, Mr. Hao will not hesitate to replace it. Four tires don't cost much. If the wheels **, the damage will be significant.
Due to high-speed driving, tires heat up quickly, expand hot and cold, and aging tires are more likely to burst. When the temperature rises, it is estimated that the gap will become larger, if you don't run at high speed, two people get married with their sons, and their married life is not satisfactory, do you want to divorce? It can be used for a while, and it is better to change the two front wheels, which is safer.
Don't make fun of the wheels, the wheels can't turn. Safe driving is the most important thing! As long as the tires harden and crack, they should be replaced over time, let alone at high speeds.
As the grip of aging tires becomes less gripping and the braking distance becomes longer, the vehicle's braking is not easy to control. Broken tires are easy to drive at high speeds**, which is a very dangerous thing to do. Therefore, for safety reasons, we still need to replace the tires as soon as possible.
Replace two front and two rear tires. Buy two new tires and replace the front wheel, the rear wheel remains the sameIf you are often driving at high speeds, simply buy four new tires and replace all the wheels in place at once. If you run into the city a lot and can't reach the high speed, don't do anything.

Need. Because the life of the tire is coming to an end, it is very dangerous to continue using it, so it needs to be replaced.
-
Yes, because the distance traveled by this tire is relatively far, and then there are particularly serious cracks on the surface, which will also affect the normal driving of the vehicle.
-
I felt that it needed to be replaced, because doing so would improve the life of the car and also make the car better, so I felt that it needed to be replaced.
-
I think you'd better replace it, because if you continue to use it, you might get a puncture.
-
It's better to change them all. Five-year-old tires have aged, and it is very dangerous to run at high speeds. Cracks on the surface indicate that it has aged.
-
If the tire is cracked, it cannot be used any longer.
Cracks caused by the natural aging of rubber. Generally, there will be some fine cracks after 3-5 years of use, if the tire is used for more than 5 years, the tire hardness is high, the tire noise is large, and the rubber properties are basically lost, and can not be used anymore, and should be replaced in time. If the tire has been used for more than 3 years, but there are some small cracks on the tread, which means that the tire is only slightly aged and can be used temporarily for about a year, but it is best to replace it if there are conditions.

If there are cracks and cracks in car tires, judge whether the tires need to be replaced according to the following methods:
1. The outer edge is worn, if you observe it in the direction of travel, there is a large wear on the outer edge of the tire, indicating that the tire is often in a state of insufficient inflation, that is, the pressure is not enough. 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 weakened;
2. Convex and corrugated wear, if it is found that the two sides of the tire landing part are convex wear, and the tire perimeter is also corrugated wear, it means that the shock absorber, bearing and spherical coupling and other components 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;
3. The surface is evenly worn, and once the tire pattern has been ground dry, it means that the life of the tire has been exhausted 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 tread, which is usually mm, and if the width of the tire is more than 175mm, it is 2mm, it should be replaced;
4. If there is wear, scratch or damage during driving, if it is found that it is timely and properly disposed of, does not affect other tires or causes minor safety accidents, and other tires are not affected by it, only the damaged tires can be replaced as appropriate.
-
A case-by-case analysis is required. If it appears on the sidewall of the tire, especially where the sidewall and triangle rubber are combined, be sure to replace it in time.
-
Cracks or cracks in car tires indicate that the tires have deteriorated. This has a certain relationship with the use of tires and the quality of tires. Under normal circumstances, a crack in a car tire alerts the owner to the need for replacement.
Is it necessary to replace it immediately? It is recommended that you go to the 4S store to ask a professional to take a look or test, and the final result will be provided by a professional opinion.

There are many reasons for tire cracks: length of use, poor driving habits, road surface causes (abrasions, scratches), natural aging or cracking of tires, the quality of the tires themselves, etc. Whether or not a tyre replacement is required depends on the situation.
So, what are the conditions of cracks that indicate that the tire needs to be replaced?
First, the tread loss is close to the wear mark.
Any brand of tire has a wear mark at the bottom of the tread groove, also known as a "warning line". Generally, the height of the wear mark on passenger car tires is millimeters (the minimum groove depth of legal tires), and the height of wear marks on truck tires is millimeters.
2. Tire cracks or bulges and other damage.
In daily driving, the owner will inadvertently run over the small iron pieces, glass ballast, iron nails and other metal foreign objects on the road, and the car will inevitably encounter tires that are punctured. Tire damage includes tread cracks, tread bulges, missing tread rubber, severe sidewall wear, and tires that have been punctured by foreign objects many times. Especially with bulging tires, there is a danger of bursting tires at any time.
As long as the tires are found to be damaged, the owner should go to a professional tire shop as soon as possible to check the tires of his car and replace them in time.
3. The length of the tire age.
The service life of tires is usually about 5 years, and if they exceed the age, they will begin to age, the main manifestation is surface hardening, and then cracks appear, losing their due elasticity, and if they continue to be used, they will lead to tread deformation and the risk of puncture. It is recommended to replace the tires in time in this case.

Hello, the tires are cracked, it is better to replace them for safety. If you are not at ease, you can go to the 4S shop to do a professional tire inspection to avoid the danger caused by accidental punctures while driving.
-
If the tire is cracked, it means that the outer tire has been damaged, which can easily lead to the bursting of the inner tube. Therefore, it is important to replace the outer tire as soon as possible so that it can be safe.
-
Hello, if there is an obvious crack, be sure to replace it, this is very dangerous.
-
To be on the safe side, it's best to replace it with a new one.
-
Needless to say? It definitely needs to be replaced, because cars are easy to break down and prone to traffic accidents when driving at high speeds.
-
First of all, it is clear to you that if the tires are in the car, they must be replaced in time. Because, when the car is running at high speed, there are unsafe factors such as falling off the tires and even firing the inner tube.
-
The crack of the tire is on the tread of the tire, and the tread is a relatively thin place on the tire, so once such a deep crack appears, it is recommended to replace it in time to reduce potential safety hazards.
-
According to the current regulations in China, when the surface pattern of the tire is worn to less than millimeters, it is time to replace it. The wear marks on the tires are also set according to this standard. But in fact, this is only a minimum requirement, and at this point, the grip and drainage performance of the tires will be greatly reduced, and the safety will be worse.
-
Generally, the normal life of tires is five years, and there will be small cracks after about three years of use, if the cracks are not large and appear on the tire tread, it is a normal aging crack or wear, which can not be replaced, but it also needs to be checked regularly; If the crack appears on the sidewall, it is necessary to check it in time and replace it if necessary, because the sidewall is the most vulnerable part of the tire, and a puncture may occur if you continue driving. If the crack is too long and too deep, it has reached the standard depth of the tire pattern, which is millimeters, and it also needs to be replaced.

The quality is very good, there are branches in 32 cities across the country, and you can consult at any time if you have any questions.

3 allTires are seriously damaged and should be replaced in time. If the tire size and model are the same, you can change only one tire. Otherwise, a pair needs to be replaced.
Tires are the only intersection between the car and the ground, all the performance of the car will be transmitted to the ground through the tires, the impact of the new and old tires on driving is very intuitive, so don't always hold the "my tires can be used for a while" this kind of luck mentality, when it is time to change.
How to change the tire:
Use a jack to jack up the body.
Before jacking up the body, use a wrench to loosen the screws, because once the wheels are suspended, it will be difficult to tighten the screws. The jack should be placed on a flat ground and should not be unstable. Lift the body until the tires are off the ground.
When unloading tires by hand, it is best to wear gloves or wrap your hands in a cloth, as the stains and oil stains on the tires are not ordinary dirty, and it can be difficult to find a place to wash your hands after changing the tires in the wilderness.

The tire has cracked and cannot be used any longer. Rubber products have a service life, such as the sealing strip of the door, which will age after a long time, and the sealing will be loose and cracking. The same goes for tires, the service life of general tires is 3-5 years, and even if you are careful when driving for a long time, there will be surface hardening, cracks and other phenomena.
Such a tire has fulfilled its mission, and it is time to change. If you continue to use it, there is a risk of a puncture.
When the aging tire was inflated, it suddenly burst and flew out, hitting the driver's front door and nearly killing him. Chongqing Jiulongpo** reported the police situation. After the incident, the police immediately investigated the surrounding scene and found that the inflated spare tire had a large crack on the outer tire, the inner tube was ruptured, and the tire had cracks in many places.
According to the investigation, the police judged that it was due to the aging of the tires and the fact that the tires fluffed out after they exploded during the pumping process, which caused such serious consequences.
Maintenance of tires.
1. When checking the tire pressure, it is necessary to inflate the air-deflated tires in time to keep the tire pressure consistent, otherwise it will cause rapid wear and tear of low-pressure tires, increase driving resistance, increase fuel consumption, and cause failures such as direction deviation;
2. Avoid hitting obstacles, when the vehicle is driving at high speed, obstacles such as tire craters will cause serious extrusion deformation of the tire between the obstacle and the rim flange, which will cause the tire cord yarn and the air in the tire to form a bulge from the broken yarn, and in serious cases, it will cause the tire side to rupture and the tire to suddenly deflat;
3. Regularly do four-wheel alignment testing and dynamic balance experiments, which is very important, according to the survey, four-wheel alignment (such as outside, front, front, etc.) is not allowed to cause the phenomenon of eating tires, and it will also affect the life of tires.

First of all, it depends on what brand of tires you use, just my tire Magis. >>>More
Generally speaking, most car owners should be in 350,000 kilometers to replace the tires, not often drive car owners will be replaced with new tires a few years after a few years of regular replacement of new tires, of course, if you do not often drive, regular replacement of tires is absolutely the right concept, but if you often use the car (drive to work), in fact, every time you change a new tire, as long as you take good care of it, you can run 7 80,000 kilometers, or even more! >>>More
Hello, the new car is 8,000 kilometers, the air conditioner is not too cool because the air conditioner lacks refrigerant The reason will not be cool, yes, I hope to help you!
The new car has been run-in before leaving the factory, but in order to keep the mechanical system in the best condition and prolong the service life in the future, it is recommended that you drive your car carefully for the first 1500 kilometers and maintain it in stages. >>>More
