Is the tread of a car tire smoothed out a sign that the tire life has arrived?

After a certain mileage of use, the tread pattern will gradually be worn out and shallow until it is smoothed, and if it is not replaced in time, the cord layer will be exposed, and there is a risk of puncture. At the same time, after the tread pattern is smoothed, it is easy to slip in driving, and the braking distance increases, which directly affects driving safety. Therefore, it is necessary to keep track of the wear of the tire pattern at all times to avoid exceeding the limit range.

Yes, because the tread is smoothed, it means that it has been used for a long time.

This is not true, the pattern smoothing indicates that the tire is more worn, the friction is smaller, and it can still be used.

The tread of the car tire is smoothed, indicating that the wear and tear of the tire has been great, indicating that it is time to change the tire.

It must be replaced, and if it is smoothed, it will reach the limit of the life of this tire, and then drive it to have a safety illusion, don't joke with your own life......

It's pretty much the same, if there is no pattern, the friction will be reduced, and there will be accidents, so you have to change to new tires.

Yes, because the car's tires are smoothed and the braking function is greatly reduced.

The tread of a car tire is smoothed, which means that its coefficient of friction will be reduced. It is easy to cause safety accidents.

I think it's time to get a new tyre.

If it is smoothed, it must be replaced as soon as possible, otherwise it is easy to cause traffic accidents.

It can be said that the life span has come to an end. There are no regulations regarding the life of car tires. Some cars work a lot and cars work less.

Some of their tires ***, others are of poor quality. If the tires and tires are flattened, the tires must be replaced. Someone is waiting.

Car tires are first ground from the steel wire and then from the tires, which is very dangerous. The tires of the car are smooth, there are no traces of gears, the brakes are prone to slipping, and the tires must be replaced at this point.

Car tires are the same as a person's shoes. They will wear out if they are used for a long time. When using them, shoes should be changed.

The same goes for car tires. Worn tires usually don't mean that your driving habits are defective. This phenomenon is a fact that will inevitably occur with normal driving.

The tires will gradually wear out and eventually lose their grip.

The thickness of the tread pattern must be greater than millimeters. The method is; Take out the coin and insert it into the groove of the tread in the direction of the top of the coat of arms, since the distance between the edge of the coin and the coat of arms is 1 mm and 2 mm, so if you can see the entire coat of arms at this point, the thickness of the tread pattern is already insufficient. Now it's time to change the tires.

For the long life of tires, there is currently no official authorization. Tire survival manufacturers generally recommend a lifespan of 3 to 5 years and replace them based on "wear" during their useful life; Many 4S shops recommend replacing tires for 3 years or 50,000 km.

Summary; According to consultations with many repair professionals, tires are often affected by tire aging, and the recommended tire replacement interval is 3-5 years or 30,000-50,000 km. Due to the different use environment, wear is considered when replacing tires, and if the wear is severe, even if it is only used for one year, it must be replaced, and for tires that are not obvious for wear and tear, tires that have been used for more than 5 years are also replaced, otherwise the risk of tire damage is likely to occur.

The degree of wear of the front and rear tires of the car is not the same, and the front wheels of family cars wear out faster.

1. The wear of tires comes from the friction with the ground, and the more friction there is, the more wear it will be. Let's take a look at the front-wheel drive car first, the front wheel is the driving wheel, so no matter what the road conditions, starting, accelerating, mountain roads, gravel roads, etc., the driving wheels wear out quickly, which is the front wheels.

2. The brake will also make the front wheel wear more reed, after stepping on the brake, because of the effect of inertia, the center of gravity of the car will move forward, that is, it looks like there is a feeling that the rear wheel wants to be cocked, and the front wheel is pressed down. In this way, the braking force is mainly concentrated in the front wheels, and the friction between the front wheels and the ground is subjected.

Ken hail socks must be more.

3. Because the front wheel is a steering wheel, it is necessary to bear the friction of the ground more than the rear wheel when steering, especially when reversing into storage.

When playing in the same direction, the wear on the tires is more severe.

Car tires are replaced about once every 6-100,000 kilometers. When checking whether the tire needs to be replaced, it is judged by the wear standard on the tire, when the wear mark in the tire planter is the same as the tire tread, it indicates that the grip and drainage performance of the tire is very poor and needs to be replaced in time.

Tires are generally worn to the point where the pattern gradually disappears, and it must be worse, so when the tires generally travel to 60,000 to 80,000 kilometers, you must often observe whether your tires have worn out, and some have even worn out, and you don't recognize the rubber strips inside.

If your car has some sounds while driving, and it has been driving for 80,000 kilometers or has been driving for 4 years. It's time to replace it.

When a car tire wears on the triangular arrow on the tire, it means that it needs to be replaced, because if it is not replaced, it will be more dangerous.

There is not much texture anymore, there is not much grip, in this case, changing the tire can better ensure safety.

Obviously, the wear of the front tire is large, and the direction is controlled, and the general tire change is to change the front to the back, and the front is new.

Tires are one of the important parts of the car, which are in direct contact with the road and ensure our driving safety. For car tires, many car owners may replace them according to the age of the tires, or according to the degree of wear and tear of the tires. Many car friends think that the tires are not scratched, there are no other major problems, and they can continue to use them.

The replacement time of car tires will vary depending on the road the vehicle is driving and driving habits, and the degree of wear and tear will also vary. So, to what extent do car tires need to be replaced? Let's start by looking at the life of tires.

Generally, the normal use of the tire life is 4 to 5 years. Even if the wear of the tire pattern is minimal after 5 years, it is best to replace it. Because the rubber on the tread will age over time, many small cracks are the cause of punctures.

For example, most of the aging parts of the tread occur on the edge of the tire or the shoulder of the tire, and long-term sunlight and rain can cause small cracks to appear on the rubber surface. These cracks indicate that both the load-bearing capacity and mass of the tire are beginning to decrease at this time. In order to reduce the risk of puncture, it is recommended to replace it in advance.

The life of car tires has a lot to do with whether they are used normally, we must ensure that the tires have been under normal tire pressure, too low or too high tire pressure will bury potential safety hazards for tires. A reminder not to trust what the eyes see. Most cars are now assembling tubeless low-pressure radial tires, so sometimes it looks a little deflated from the outside, but it doesn't necessarily suffer.

A professional tire pressure mechanism is the only way to detect tire pressure. In addition, the tire pressure must be detected in a cold state, and in the case of a hot measurement, it must be subtracted from the measured value to be correct. Not only aging, but tires also wear out naturally, so to what extent are car tires worn out and do they need to be replaced?

Serious aging, observe the tire tread and tire wall pattern, you can find that if there is a general cracking, the tire has aged severely.

Experts have introduced one or two small patches and frequent checks that can cope with everyday use, but can be dangerous if used regularly. So, how many times are there often? For the convenience of the consumer's memory, experts recommend not to repair more than 3 times.

What actions accelerate tire wear, overloading, speeding; The packaging is not in good condition; Tire pressure that is too high or too low does not meet safety requirements. Tire repair due to internal injury or air bubble repair in the tire curtain wall layer; Excessive wear or corrosion on the surface of the tire.

If you find that there are wear marks on the surface of the tire, and there are some cracks, it means that it needs to be replaced, because there is a high chance of a puncture if you continue to drive.

One is when the tire pattern has been smoothed out and has reached the limit, and the other is that the tire has been six years old, even if the pattern has not reached the limit, it needs to be replaced.

What is the condition of the car tire wear, it means that the car tire is worn to the point that the tire teeth are gone, which means that the tire needs to be replaced urgently, because it is easy to burst the tire and it will be very dangerous.

The following are the four situations in which car tires need to be replaced: 1. Serious tread wear generally There will be wear marks in the middle of the tread, and the thickness of the wear mark is 2mm, if the thickness of the tire is worn to 4mm away from the limit mark (that is, 6mm from the deepest part of the groove), the tire should be replaced. 2. The number of tire repairs is too frequent, in addition to wear, the tire is punctured by sharp objects is also the main reason for the tire life, if the tire repair method is appropriate, one or two tire repairs are not very affecting the driving, but if the tire repair times are more than three times, you need to pay attention, because no matter how tight the tire repair is, there will always be a gap between the original material, so that in the case of high-speed and high-temperature driving, the temperature in the tire will still occur after the temperature rises, and the danger of puncture will still occur.

3. The aging of rubber itself is a material that is easy to age under the influence of external light, heat, moisture and other factors, slowly cracking, hardening, becoming fragile, and finally completely losing its use value, so don't think that the car does not need to replace the tire if it is not opened for a long time, if the storage environment is relatively bad, the tire will slowly not be used. 4. Flat tires, bulges, and broken tires also need to be replaced.

Regarding the landlord's concern about "car tires are not worn out as flat?" "Here's my personal opinion:

Car tires wear is not the same as the specific reasons:

1. Excessive wear of tires on both sides: the main reason is insufficient inflation, dry draft or long-term overload driving. When the inflation volume is small or heavier, the contact surface between the tire and the ground is larger, so that the tire is in contact with both sides of the ground, participates in the work, and forms early wear;

2. Excessive wear on the tire side: the main reason is that the front wheel alignment is inaccurate. When the camber angle of the front wheel is too large, the outer edge of the tire forms early wear, and when the camber angle is too small or absent, the inner edge of the tire forms early wear;

3. Tire track tooth surface wear: the main reason is that the front wheel is not properly aligned or the front suspension system is not in proper position, the ball joint is loose and other reasons, so that the normal rolling wheel slides.
