I am a novice driver, I would like to ask how to distinguish the advantages and disadvantages of tir

Hello! Here's how you can tell if a tire needs to be replaced

Point 1: If the tire is aging (for example, there are countless small cracks in the tread groove or sidewall that are about to hurt the carcass), the tire needs to be replaced in time, regardless of how long the tire has been used and how much it has been worn.

The second point: if the depth of the groove left in the tire pattern is at or below millimeters (there is an indicator mark indicating this depth in the groove of the longitudinal straight bar of the tire tread), the tire must be replaced, because the drainage capacity of the tire has been greatly reduced, and the vehicle will be more dangerous to drive in wetlands.

For example, although the tire can still be inflated after being crushed by the lack of air, it is recommended to replace the tire with a new tire in time because the internal structure of the tire may have been damaged. In particular, it should be reminded that bulging tires should not be used any longer.

Whether it is recommended to replace the tires is recommended to refer to the above, which is not necessarily related to the number of kilometers and time used by the tires.

Generally, two situations need to be changed.

1。The lowest part of the pattern wear is lower.

2。The tires are deformed.

The former is prone to punctures and brake failures, and can be measured by yourself.

The latter is particularly prone to punctures, and the phenomenon is to find that the car shakes left and right no matter what speed it is.

Introduction: How to identify whether the tires of the car need to be replaced, if the tires of the car have certain scratches, then you need to go to the repair shop to replace the tires of the car. Because the tires of the car are bulging, then the car may easily cause a specified impact in the process of driving, and from the point of view of time, if a car tire is used for more than five years, it is recommended to replace the car tire to a certain extent.

Because an ordinary tire has reached the wear level in five years of use, it may have a certain impact on daily driving. And you can also go through the mark on the car tire, if the tire on the tire than a line on the mark on the tire has disappeared, then you can consider replacing the tire, because the tire is relying on that to carry out a certain anti-skid. <>

If that line has been worn out, then the impact on the tires is actually quite large. You can also go from the mileage of the car to ** whether the wheel car should be changed. If the mileage of the car reaches about five to 100,000 kilometers, the tires can be replaced, and the wear points of the tires can be carried out to a certain extent.

If the deepest wear point of a tire has caused a certain impact on the use of car tires, then it is recommended to replace the tires in a large way. Moreover, the car tire is also a rubber product, if the car tire is not used, the car tire will also undergo a certain aging, will become inelastic and there will be a certain crack and roll out, so it is recommended that the car tire be replaced in about five years.

The work of car tires also needs to be based on the real situation of the car, if the car is driven on some harsh roads, then it is recommended to change the car tires quickly. If the car tires are driven on the ground line of some benefits, they can still be replaced to a certain extent according to the real situation.

You can see whether there are cracks on the surface of the car tires, whether there are bulges, and if it is more serious, it should be replaced. The problem that needs to be paid attention to is that when you check the lead, you can go to the repair shop to lift the car up for inspection, so that you can check more carefully.

Be sure to observe the changes in the car's tires, if the tires have been swollen, and the bulging is very serious, then it needs to be replaced in time.

If the car tires are already bulging, or the cracks in the car tires are very large and have affected the use, it is necessary to replace the leakage. When replacing, be sure to find a professional company to return to Tongtong to replace, and pay attention to the quality of the slippery tire.

Problems that should be paid attention to when choosing new tires and how to distinguish between good and bad:

When choosing new tires, you can't just save money, go to a roadside store without qualifications to replace retreaded tires at will.

At present, there are few retreaded car tires in China, and it is necessary to buy cautiously when encountering particularly cheap car tires known as retreaded. It is also important to note that some businesses sell retreaded tires to consumers in the name of "ninety percent new tires" that have not been worn for a long time.

The sidewall certification mark is complete, including China's compulsory certification mark CCC, the United States Department of Transportation certification mark DOT, the EU certification mark E1, etc. Tires that pass these certifications have a basic quality assurance.

Other signs on the sidewall are complete, such as manufacturer or place of origin, trademark, specifications, precautions, internal materials, rims, production date, etc. Anything that can be marked should be a regular manufacturer.

Tire appearance; Smooth appearance, clear handwriting, thin flash, rubber (the surface of the tire is like a thorn, it was cut off when it was sold, but the root is left) is a high-quality tire.

Observing the color and luster of the tire, from the point of view of the grain, in general, the groove is relatively shallow because the processing of inferior retreaded tires is not standardized. In terms of color, low-quality retreaded tires look brightly colored and shiny, while regular tires are relatively dark. The retreaded tires are dull in color and shine.

Generally, the new tires of regular manufacturers will be labeled, and there will be no problem when you buy them. In addition, when changing new tires, you will generally do dynamic balancing for free, and as for the four-wheel alignment, you can ask the master in the store if you want to do it.

To choose a tire, you must first choose the right type of tire that meets the specifications of the model, and you should also choose the type of tire according to your own needs, generally sports tires, winter tires, all-weather tires, etc. As for the worst main thing to see the strength and after-sales service of tire manufacturers, the quality of general big brands is first-class. If you have a lot of money, choose a foreign brand Michelin; If you want to be cost-effective, choose domestic tires.

These brands are all produced in regular factories and are also common on the market, so the quality should be stable and you can buy them with confidence. Like some unknown miscellaneous tires, it is better not to choose, after all, driving is a matter of life safety

Hello! When buying tires, you must first determine the specifications of the vehicle's original tires. Usually, the identification of car tire specifications is**r**, and the part is a number. (e.g. 205 55R16).

Michelin-branded tires maintain their excellent overall performance, while some focus on comfort and quiet, while others focus on sportiness and handling. You can choose according to your hobbies.

When choosing tyres, you need to consider the vehicle's performance (e.g., supercars, SUVs, small and medium-sized cars), driving habits (e.g., gentle driving or intense driving style) and hobbies (e.g

comfort, high tire noise requirements), driving road conditions (e.g., high-speed, gravel, winding roads, etc.) and climatic conditions (e.g., winter ice and snow), etc., and then choose the right tire for you according to the positioning of Michelin tire products.

<>1.Car tires are rubber products that have a gradual aging process over time. Usually the service life of family car tires is about 5 years.

After this age, even if it is not very useful, such as the spare tire is not used all year round, the toughness and tension of its rubber composition will deteriorate, and it can occasionally be used temporarily on the ground, but it cannot be used as a new tire. If you look closely at the surface of the tire, you will notice that there are tiny cracks in the grooves. The sidewall of a tire is where the most pressure is experienced in the entire tire.

When a tire is unfortunately scratched by a road tooth, it means that the tire is damaged or deeply scratched. At this time, the risk of puncture is extremely high. Another case is bloating.

2.The sidewall is often bulging and feels like a large pimple to the touch. It is easy to find that when the tire is bulging, it means that the metal cord on the inside of the tire has broken and relies entirely on the rubber to withstand the internal pressure.

Normal tires can pass through extreme road surfaces such as speed bumps or bumps, but damaged tires are under a lot of pressure instantly, and there is a danger of being punctured. When we usually check, we should pay attention to the tread pattern of the tire. The pattern on the surface of a normal tire is relatively clear.

If the tread pattern on the surface of your tires is worn out, and some of them are smooth, it's time to replace them. Otherwise, the tire will become thinner and more likely to puncture. This is actually quite understandable.

Just like the shoes we wear, if the soles are thinner after a long period of polishing, they will be more violent and easy to break, right?

3.When the tire tread is worn, it is easy to slip in rainy days, and the braking distance is too long, causing the vehicle to lose control. There will be traces of the wear limit on the tires.

Be careful when checking. There will be a little bump under the grooves on the tread, which is a sign of the wear limit, and this triangular sign is also displayed on the side of the tire. Look closely and you'll find Bibo.

Cracks refer to cracks on the surface of tires due to self-branching trillions of aging or external impact. If the clearance length is more than 6 mm and the weave inside the tire is visible to the depth, the tire must be replaced. Pay special attention to bulging, as tires are in danger of being punctured at any time.

Bulging occurs if the tire is subjected to a strong impact from an external force, causing the tire wall cord to break. If this situation continues, the risk of a puncture is high, and a tire change is recommended.

To see whether the surface of the tire is seriously damaged, whether there is an abnormal phenomenon of cracks and bulging, the life of the general tire is 3 5 years, and it can be decided according to the use of your own car tires.

You can see the degree of wear of the pattern, when the wear is close to the wear mark, it means that it is more difficult to change the tire, shouting to check whether the tire has reached the age of the Zheng ruler cover, and whether the surface is cracked.

If the tire is worn out severely, there is a bulge or crack, and the service life expires, you should go to the car repair shop to replace it in time.

When the wear marks reach the limit, n As we all know, tires have various numbers, words, grooves, etc., which indicate the parameters of the tire. But do you know how the wear marks of tires are formed? The first wear marks are on the sides of the wheels and are a small shape.

When the wheel is worn and touches the triangle cutting angle, the wheel must be replaced. Let's start with the wear indicators. If you kill the direction first, the front tread will be exposed.

You can see small rubber blocks that protrude into the groove. Wear indicator points. The height of the dot is in millimeters.

The depth of the tire pattern is as high as the small protrusions you see, and at the end of the day, it must be replaced. I'll teach you how to check with a cover digging one-dollar coin. If you put a coin in the ditch, the underside of this coin is about the same as the tread.

Then you should change the tires, but when you put in the new tires, it will cover about 1 4. This can be used as a standard to refer to. When the depth of the groove left by the tire pattern is below, the drainage capacity of the tire is greatly reduced, so it is dangerous to drive in wetlands.

In addition, damaged tires need to be carefully measured for replacement. For example, tires that have been crushed due to insufficient inflation can be driven with inflation, but the internal structure of the tires may be damaged, so it is advisable to replace them with new tires immediately. It is important to note that drum tires cannot be used any longer.

When many people maintain their cars, they pay the most attention to the maintenance of engine oil, brakes, engines, etc., and do not pay much attention to tires. Many people's car tires have been used for 6 years, or have run 80,000 kilometers, and they are still on the road, so it is recommended to replace them.

Tires rub against the ground every day and "deteriorate" after a period of time. Tires that have deteriorated in this way can no longer be used. It needs to be replaced.

So, how do you know if you need to change your tires? You'd better keep these four points in mind. See if the surface of the tire is punctured.

If your tires are less than 6 mm, in this case, the inner tube has not yet been affected, and you can replenish it immediately. If it exceeds 6 mm, the trachea is likely to be broken, and instead of continuing to operate, it will need to be stopped for inspection and replacement. It depends on the age of the tire.

When the tires are 6 years old or the car has traveled 80,000 kilometers, be sure to replace them.

Determine whether a tire needs to be changed by looking at the wear of the tire, whether the tire is bulging, the number of tire repairs, and the time of use. The best way is to judge by a raised line on the tyre, if the tire is worn close to this line, it needs to be replaced.

I think you can look at the tread depth of the tire, if the tread depth is less than three millimeters, then it means that it needs to be replaced, because the situation is already badly worn.

In fact, for many of my bridge pins, I don't know much about tires. Generally to distinguish the quality of a tire, you can first observe the tire pattern color and gloss, retreaded tires because the processing is not standardized, so the groove will be slightly shallow; The color of the retreaded tires will be particularly bright, and the regular new tires will be darker. Not only that, the logo of retreaded tires is re-affixed, and these signs can often be picked off by hand.

Therefore, when choosing tires, it is best for us to go to a large tire retailer like Tuhu and buy them through regular channels. At the same time, we must also learn to see the basic information and performance of tires by ourselves, we can pass the tire TUV Rheinland China-Mark (China Mark) certification certificate (it is jointly launched by TUV Rheinland and Tuhu Car Care Car Tire Performance Evaluation Certification System, and can only be obtained after passing the test), scan the *** on the code logo, to view the basic information and performance of the tire you choose. And using this as the basis for selection, not only can we ensure the quality of the tires we choose, but also allow us to quickly choose the tires we want, which is super convenient.

Hope to give a big thumbs up.
