How to tell if it s time to change the tire

If the tires of the car are bulging and peeling, or obviously damaged, the tires of the car should be replaced if they are used for more than five years or more than 70,000 kilometers.

The production of automobile tires consists of a series of technological processes, the main processes are: raw material processing, batching, raw rubber plastic refining, rubber mixing, canvas calendering, tread extrusion, tire parts manufacturing, tire building, green tire shaping and vulcanization.

See if the wear limit has been reached, there are small bulges in the tire grooves, and the flat will reach the limit, if you don't reach the limit to see if there are serious trauma on the surface, bulging, whether the tire hits the ground crack is serious.

Wear and tear of the tire, whether there are cracks on the sidewall of the tire, whether the tire production date is 5 years

Look at the wear indicator points. How can you tell if a tire needs to be replaced? First of all, look at the wear indication point, beat the steering wheel to death, the tread will be exposed, and you can see the raised small glue dots in the groove, which is the wear indication point, and you must change the tire when grinding to the indication point.

2. Look at the production date. Look at the tire production date, the tire is a rubber product, even if you don't open it, put it in the garage, the tire will slowly age, lose its original elasticity or produce cracks, and the tire of about 5 years has begun to age. The production date is on the side of the tire, four digits, the last two digits represent the year of production, and the first two digits represent the weeks of production.

3. External intuitive judgment. In addition to the above two, it is also necessary to see whether the tire has problems such as eccentric wear, cracks, and bulges. Eccentric wear is the same tire, and the wear on both sides is inconsistent.

A crack is a crack on the surface of a tire that is naturally aging or is impacted by an external force. If the gap length is more than 5 mm, the weave inside the tire can be seen, and the tire will have to be replaced. If it is bulging, it is recommended to change the tire immediately to avoid a puncture.

Whether the tires should be replaced, the first thing is to check the use of the tires, if the wear is more serious, they should be replaced or new, and they should be replaced after a long journey.

1. Judging from the age of tires, experience generally believes that the life of new tires is 4 years from the beginning of landing.

2.Judging from the mileage, the general tires should be almost worn out after driving 50,000 kilometers under normal use conditions, or the sidewall is aging under long-term fluctuation and stress, so it is also recommended to update the tires.

3.From the point of view of wear, when the tire has been worn to the wear mark, it means that the depth of the drainage groove is not left, and the tire must be replaced immediately.

There are two aspects that determine whether to change the tire or not.

1. There is a wear warning line on the tire. Wear to that position indicates that you should replace the Trooper Ringing tire.

2. Tire damage, cracks and other conditions that affect driving safety need to be replaced with new tires.

<> "As a consumable product on the car, the tire has its service life. So the question is, how to tell if the tires should be changed?

1. Check whether the tire has cracks, if there are deep cracks, they need to be replaced immediately.

2. Check the tire drainage groove, that is, the depth of the tire groove, if it reaches and below, the tire should be replaced immediately.

3. Check the side of the tire, whether there is damage and the tire bulges, and replace the tire immediately if there is.

4. Usually the service life of the tire is 3 5 years, and when the service life reaches the limit, even if the tire is new, it must be replaced in time.

There are several situations to determine whether a tire needs to be replaced:

The tire tread is close to the tire wear mark, the tire is bulging or cracked, and the tire has expired.

The tire tread is close to the tire wear mark. Any brand of tires on the market will set a wear mark at the tire groove, the tire wear mark height of the general family car is mm, and the tire wear mark of the truck is mm.

Automobile tires are one of the important parts of the car, which is in direct contact with the road surface, and the car suspension works together to alleviate the impact of the car when driving, and ensure that the car has good ride comfort and driving smoothness; Ensure that the wheels and the road surface have good adhesion; Improve the traction, braking and passability of the car.

Bearing the weight of the car, the important role played by tires in the car is becoming more and more important. In 1895, with the advent of automobiles, pneumatic tires were widely developed, and the first samples of automobile tires appeared in France in 1895, which were single-tube tires made of plain canvas, although there was tread rubber but no tread.

We seem to pay little attention to tires when we usually use cars, so how long do car tires generally last, and what should beHow do you know if you should change your tires?

Generally, in the case of daily use, the life of tires can basically reach 4-5 years.

However, we cannot judge the principle of tire replacement based on this set of service life data alone. We also need to check the use and wear of tires at all times.

1.Tire wear:In the drainage groove of the tire, there are generally a number of small protrusions to detect the wear limit of the tire, when the tread of the tire is worn to the level of the bulge, it indicates that the tire has been worn to the limit of use, and needs to be replaced in time.

2.Tire rubber aging:Observe whether the tire rubber is aging and cracking, and replace the tire in time when it is found that the tire sidewall has serious aging cracks.

3.When the tire is seriously worn unevenly or is subjected to a strong impact, resulting in tire deformation, it is also necessary to replace the tire in time.

Many people's habit of taking precautions is still commendable. After all, if you really wait until a puncture to change your tire, you can put yourself in a very dangerous situation. Today's topic is five signs of tire failure.

After learning this, you will know how to judge when it is time to change the wheel family.

These are the five signs.

1.Severe tire wear.

Regardless of the tire brand, the wear indicator symbol is basically set in the groove position of the tread. When you find that the tread depth of the tire has worn down to the same height as the raised indicator ruining the suihui rubber, it means that it is time to replace the tire. Most car tires have a height of millimeters (mm) (this height is also the legal minimum groove depth for tires) and truck tires have a height of millimeters (mm).

2.Sidewall cracks.

The side of the tire is the weakest part of the tire and is not as strong as the front bottom of the tire. The cord layer plays a powerful role. Of course, once the cord layer on the side is scratched, there is a very high chance of being punctured.

Don't think that a tire repair is enough. The sidewall of a tire is very prone to bending and deformation when rolling, which can affect the detachment of the repair material (surge phenomenon) in the long run. In addition, if the crack is more than 6mm, the braid can already be seen at depth, and there is no point in repairing it.

3.The tires are aging.

Over time, there will definitely be slight aging (tread cracking, rubber hardening). Especially if the tire has passed the replacement cycle, we must be diligent in caring about the condition of the tire. If the degree of aging is already critical, we need to replace it immediately.

4.Bulging tires.

When the wheels are subjected to an uneven impact, a small long bao or a large barbecued pork bao will expand somewhere. At this point, the tires can be ** at any time, and it is very dangerous to continue driving. Of course, you should replace it immediately, otherwise you will carry an untimely bomb in the car.

5.The tires are punctured and repaired too often.

If the puncture hole is large or the number of repairs is too much, it will also affect safe driving. This time, you can solve it without repairing the tire. Especially at high speeds, the tire pressure is quite high.

If you drive for a long time, there is a certain probability of a puncture. I believe that friends have basically seen some high-speed tire bursts on the Internet (very dangerous). Of course, friends must not be lucky and should be replaced immediately.

About hot searches:1After 8 years of use, the tires have not been replaced.

2.There is a bit of abrasion on the side of the car's tire. What happened?

3.Does sealant corrode steel rims?

Millions of car purchase subsidies.

<>First of all, the best way to know how much wear your tires are is to look at the thickness of the tread groove from the top to the bottom. So in order to facilitate the owner to observe the wear more intuitively, basically the bottom of the tread groove of each tire will be equipped with a wear mark. Generally, the height of the wear mark on the tire of passenger cars is millimeters (this height is also the legal minimum groove depth of the tire), and the height of the wear mark on the truck tire is millimeter.

When the wear mark is as aligned as the tread, it means that the tire is almost worn out and should be replaced in time.

Don't underestimate the degree of wear, when the tire pattern is about to be worn, the grip performance must be reduced a lot, which will affect the braking effect of the car, and there are certain safety hazards. Secondly, the drainage of the tires is also affected, so when driving in rainy days, you may play a little more steering wheel, and the danger of "water drifting and slipping" will occur. So that would explain why it had to be replaced when it was worn out.

Of course, it is not enough to check the wear and tear of the tires, and if there is a bulge or serious cracks in the tires, they also need to be replaced in time.

As for the problem of uneven tire wear, it is most likely due to inaccurate front wheel alignment. When the camber of the front wheel is larger than normal, the outside of the tire will wear out early. If the camber angle is small or none, the inside of the tire will wear out early.

At this time, it is necessary to go to the garage to do a four-wheel alignment (to restore the angle of the tire), otherwise the problem of uneven tire wear will become more and more serious. It will not only reduce the handling performance of the whole vehicle, but also affect the service life of the tire, and even have a certain chance of a puncture, so you must not ignore the problem of uneven wear.

1.Look at the tire tread depth.

The depth of the tire pattern is an important indicator to check whether the tire needs to be replaced, each tire has a wear mark in the pattern drainage groove, when the tire is worn to the mark, the tire needs to be replaced, and there is an important criterion is time, there are many people who usually use the car is not very much, the annual mileage is not much, the tire pattern is still very deep for several years, this situation needs to replace the tire according to the age, because the tire is a rubber part, with the increase of the use of time, the tire will have the problem of oxidation cracking, Tires generally need to be replaced in about 6 years.

2.Look at the degree of aging of the tire.

The rubber shelf life of the tire is three years, and there will be many small cracks on the tire sidewall beyond the rubber shelf life of the tire, and the more lines prove that the tire aging is more serious. In this case, it is advisable to change the tyre.

3.Look at the tires to find the tread on the ground.

Three days or four big gullies in the tread, seriously ** There are protruding small bumps in the ravines, and that small bump is called the tire boundary point. Tire wear should not be lower than the cut-off point, below which it is easy to puncture. Therefore, when the tires are worn to the point close to the cut-off point, it is recommended to replace the tires.

4.Look at the extent of the damage to the side of the tire.

When we talk about a tire side injury, we usually mean that the shoulder and sidewall of the tire have been nailed or scratched. The weakest part of the tire is the side of the tire, if it is damaged, it will not only increase the hidden danger of puncture, but also the difficulty of repairing is relatively large. 5.

Check the tires for bulging.

If the tire bulge must be replaced, once you find that the tire is bulging, please go to a professional repair shop immediately to replace the tire, do not take chances, thinking that just bulging a small bag is not a big deal. Bulging tires can easily cause punctures, which can be very dangerous when the vehicle is moving.

There are several conditions for judging whether the tire needs to be replaced: 1. The service life and kilometers are generally 60,000 kilometers or three years, of course, mainly depending on the wear degree of the tire; 2. The degree of wear of the tire, if the tire pattern has been worn very seriously, it should be replaced; 3. The aging condition of tires, such as cracks in tires.
