How do you see tire wear? How to look at the wear and tear of tires

There will be a bulge in the groove of the car tire, and the tire must be replaced when the bulge reaches or below the tread surface in millimeters.

1. There are tire tread wear indication marks on the tires, and these slightly protruding tread wear indicator marks are located at the bottom of the tread groove with a height of millimeters (the legal minimum groove depth).

2. If the tread rubber tread block wears to the same height as these protruding markings, the tires should be replaced immediately, as it is no longer safe to continue driving.

3. Generally speaking, the service life of tires is limited to 4-5 years, and the degree of wear is limited to less than the tread groove.

4. Tires are made of rubber, and even if the stock is not used, the rubber will age naturally. After 5 years, there will be many small cracks in the rubber of the tread, even if the wear is small, it is recommended to replace them, because small cracks are the cause of punctures.

5. In addition, the road surface conditions that are often driven, whether the load is driven, and the tire repair situation will affect the service life of the tire, and whether to replace the tire should be comprehensively judged to ensure the safety of the car while driving.

Hello! You can tell if a tire needs to be replaced based on the following methods: Point 1:

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 can be dangerous to drive in wetlands.

The second point: 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 worn out.

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.

One. The middle pattern of the tire is smoothed, which means that the tire pressure is too high. This can be the case with particularly wide tires.

If the tire has been hit with nitrogen, it is generally rarely ground in the middle, but if the air has been played, the water removal of the compressor is not good, and there is too much moisture in the air, and it is easy to have intermediate grinding.

Two. One side is smoothed, the other side is fine. Typical eccentric grinding.

In this case, there is a problem with the four-wheel alignment data, mainly because there is a problem with the toe-in, and it should be noted that it is not only the front wheel, but also the toe-in. Both the front and rear wheels have toe-in.

When the tires are eccentric, you can ventilate or redo the wheel alignment according to the situation.

Front and rear wheels, first change the tire position, left front to right rear, such exchange, another year, if you use it, the problem is not big, after a year, buy new tires, put them in front, put the front tires in the back.

How to observe whether the tires should be replaced, the old driver teaches you to identify the degree of tire wear at a glance.

1.Tire wear is broadly divided into the following situations: Outside edge wear Causes: If the outside edge of the tire has a large ,.. of wear

2.Convex and corrugated wear Causes: If you notice that the sides of the tire landing part are convex and worn, and the tire perimeter is also corrugated.

3.Uniform wear on the surface Reason: Uniform wear of tires is a normal phenomenon, once the pattern is dry, it means that the tire must be replaced. .

4.Cause of "dark injury" in the tire: The rubber layer of the tire after the vehicle collides with a hard object, or after driving in a deflated tire state.

5.Center Part Wear Cause: If you find that the center area of the tire landing part is severely wornLook

1.Look at the tire: between the tire treads, there are three or four annular grooves (drain grooves) around the tire, and there will be a "bump" mark (mm height) in the grooves, which is lower than the tire tread next to it, and when the tire pattern wear is the same as this bump, it means that it needs to be replaced.

This is a "wear mark" specially designed by many manufacturers for the safe use of tires (but not all brands of tires have this mark). Drawings:

2.If the tyre does not have wear marks, it can be tested with a special measuring tape: when the ruler is graduated in millimeters, it has reached the safety limit and must be replaced. Drawings:

3.The following tire has worn off a lot of wear marks, which is beyond the limit and very dangerous. Drawings:

There is a horizontal line in the tire groove, if the horizontal line and the tread are basically the same, you have to think about it, from the mileage point of view, the normal seventy or eighty thousand kilometers should also be changed!

Nowadays, cars have gradually integrated into our lives and become an indispensable part! Cars have brought convenience to our travel, but irregular inspection and replacement of auto parts will also bring us a lot of dangers, especially tires, brakes and other important items related to safety, which may lead to the safety of others, and even the lives of their own and even their families! Today I have collected some common sense about car tires:

The fetal wall was scratched.

A scratched tire wall is indeed more dangerous than a tread injury. The strength of the steel wire at the tire wall is weak. If the damaged part is located on the underside of the logo near the edge of the wheel, the tire must be replaced, and it will be crushed and deformed during the tire installation process after repair, and the repair effect is difficult to guarantee.

At present, it is difficult to park on urban roads, and there are many cases of tire wall puncture caused by the friction between the tire and the step water chestnut angle when parking sideways, which often leads to the deterioration of the tire wall quality.

The package is deformed. Tire deformation is very dangerous. If the tire is deformed, it is best to go to the repair shop to check and deal with it as soon as possible.

In general, the tire is replaced directly. If this happens to the tire, it proves that the metal coil inside the tire has been deformed or broken, and there is a high risk of a puncture if you continue driving.

The bubbles are deformed. Repair tires frequently.

Many of my friends don't care much about flat tires. Can the same tire be repaired frequently if it has been punctured repeatedly? Reconditioning the tire twice will not affect the use of the tire, but after more than three times, it is recommended to replace the tire for safety reasons.

At high speeds, the temperature inside the tires rises, and the excessive damage is compensated, but it still increases the probability of danger.

The above situation is basically not considered, and it can be replaced directly. The following situations need to be observed by yourself.

Severe aging. Observe the lines on the tire tread and sidewall. If cracks are widespread, the tire is seriously aged.

Although the mileage is not long or the use time is short, the tack pants should still be replaced in time. Otherwise, aging tires are prone to punctures due to increased temperature during high-speed driving due to the weakened strength of the sidewall.

Severe wear and tear. Each tire tread groove has a sign of the wear limit, which is about 2mm thick. It is recommended to replace the tire thickness when the tire thickness wears to a distance of 4mm from the limit mark, i.e. about 6mm from the deepest part of the groove.

Wear lines. Enlarged sheet view.

Conclusion: Drivers should check their tires regularly. In case of the above tires, it is recommended to replace them as soon as possible. Changing early and late is a must. It's been a good few days, and it's too late to regret it after the accident.

If you think it's any use, please. Do I have a number?

Millions of cars are bought to make up for the hunger stickers.

The best way to see how worn a tire is to look at the thickness of the tread groove from top to bottom. Each basic tire has wear marks at the bottom of the tread groove. The height of the wear marks on car tires is generally mm (this is also the legal minimum groove depth for tires) and the height of wear marks on truck tires is mm.

If you find that the traces of wear and tear are the same as the tread, it means that the tire is almost worn out, and it should be disassembled and replaced in time. When the tire tread is worn to the same extent as the car mark, the grip performance will definitely be reduced a lot, which will affect the braking effect of the car and cause certain safety hazards. Secondly, the drainage of tires also has a certain impact, so when driving in rainy days, you may play a little more steering wheel, and there will be a risk of "water drifting and slipping".

Therefore, when the degree of tire wear reaches the wear mark, it is necessary to replace the tire in time, which is not only convenient for driving, but also safer. Of course, the degree of tire wear is only one of the factors that affect the life of the tire. When the tire is aging and bulging, the tire should be disassembled and replaced in time.

You must know that some friends rarely use cars and have no tire wear at all. But because tires are rubber products, tires will age over time, mainly manifested as tread cracking and rubber hardening. Especially if the tire has passed the replacement interval, be sure to check the condition of the tire frequently.

If the degree of aging has damaged the carcass, it needs to be replaced in time. As long as the tire has a bulge, the rubber on the damaged part is very thin, easy to leak, or even punctured directly. Knowing that punctures while driving are often dangerous, be sure to take them out and replace them in time.

Secondly, if the previous tire was violently impacted, resulting in deep cracks in the tread or sidewall, it also needs to be replaced at this time, otherwise there is a great safety hazard.

1. Fingers touch down the ribs of the tire, and there will be protrusions blocking it every other section, and the protrusion is the tire wear mark, corresponding to the TWI mark of the tire shoulder. The protrusion thickness is.

2. Observe the tire tread and the lines on the sidewall, if cracks are common, it means that the tire has been seriously aged. At this time, although the mileage is not long or the service time is not long, it still needs to be replaced in time. Otherwise, aging tires are prone to puncture due to the weakening of the sidewall strength and the rise in temperature at high speeds.

There are generally three situations in which car tires are worn:

Outside tread wear, middle tread wear, inside tread wear

The outer tread of the tire is worn, generally the problem of the vehicle's four-wheel alignment, the camber angle is too large, only the independent suspension can be adjusted, if it can not be adjusted, it means that there is a problem with the chassis of the car, and it needs to be repaired by a professional repair shop.

The middle pattern of the tire is worn, which is generally caused by the high tire pressure of the vehicle tire, at this time you can check the tire pressure of our vehicle, the tire pressure is too high, you can release more gas, put it in the standard position, and there is a tire pressure standard on the side of the general driving position.

The problem of inner tread wear and outer tread wear of tires is the same, generally the dynamic balance of the car is not normal, and it is necessary to go to a professional repair shop to check and repair. If the tire is not bright and wearable, it means that there is a problem with the chassis of the car or a problem with the positioning or balance of the car, which requires us to send it for inspection in time to avoid driving danger.

Hope to excite Huaiye!

Check the tire wear mark baseline of the vehicle on a regular basis, and when the tire wear level on the outside of the tire exceeds the baseline of the replacement, it indicates that the tire must be replaced.

Whether the ripples on the tire are shallow, shallow means that the wear is severe, whether there are many cracks on the tire, too much Bu Tanhong indicates that the rubber aging is serious, and the Xinchi tire is an arc-shaped tire surface, if the ground is flat, it means that the wear is also very serious! Brochure.

For the wear of the tires, you can look at its tire flower silver shed, now Kai Zhao grinds badly, and it can also be seen that the tire pressure is normal under the condition of some appearance of Fengsun Ze's wheels.

Look at the method of tire wear: 1. Generally speaking, the life of normal tires is 4 to 5 years. 2. Most of the parts of the old sail attack start from the edge of the sidewall or shoulder, and the long-term sun and rain will make small cracks appear on the rubber surface.

1. The service life of automobile tires is directly related to the life safety of our drivers and passengers. 2. I believe we all know how high the risk factor of a puncture is when driving, aside from the puncture, if the tire is seriously worn, it will also lead to poor grip of the car and easy to slip, plus the phenomenon of rain or snow, low temperature and icy road surface will seriously threaten the life safety of our car group, so the majority of drivers should pay attention.
