How does the summer tires "restless" appease?

With the advent of hot summer, car tires have become uneasy in high-temperature environments, and puncture accidents have occurred. According to incomplete statistics, 46% of traffic accidents on the expressway are due to tire failures. Among them, a puncture accounted for 70% of the total number of tire accidents. Therefore, the prevention of punctures is the key to driving safety in summer.

Except for a few car owners who have experience in puncturing tires on the road, they will pay special attention to the tire condition of the vehicle. When more tire owners change the tires, their understanding is rather vague. Most of the owners of the tires are also forced to replace the tires. After a puncture occurred, etc., it was necessary to replace the tire. However, such forced replacement of tires is a matter of remedy. Failure of tires has brought about danger.

First, when should the tires be replaced?

The wear and aging of tires are closely related to the use of the vehicle and the driving environment. It is impossible to change the tires as long as it is considered. The owner can determine whether to replace the tires according to his own judgment.

1. When the tire wears to the limit mark of wear, it must be stopped. There is data that the depth of the tread pattern is less than 1.6 mm is the wear limit.

If you are driving on a slippery surface with low friction, it is best to ensure that the tread pattern is twice as thick as the above. You can buy a gauge to measure the thickness of the tread pattern, or you can use a one-dollar coin to insert the tread groove along the top of the national emblem, because the distance from the edge of the coin to the top of the emblem is between 1 and 2 mm, so if At this time, you can also see the emblem of the entire national emblem, indicating that the thickness of the tread pattern is already insufficient.

2, tires have a serious aging phenomenon needs to be replaced.

Tires are rubber products, so in addition to wear and aging will naturally age, so the general tires have a three-year shelf life, but it is certain that the purchase of the tire is not used, the natural aging rate and speed is not the same as installed in the car .

3. Tyre deformation or bead damage tires, lack of gas driving tires caused by the tire side of the tire was damaged, chemical corrosion of the tires can no longer continue to use.

The sidewall of the tire is the most vulnerable part, and if it is a wound, it is extremely prone to danger even after repair. If there are visible cracks and cuts in the sidewalls of the tires, there is a risk of leaks in the future and, more seriously, a puncture.

4, if the tire bulging, it can not continue to use.

What kind of situation is an abnormal drum kit? This is usually due to the lack of strength on the outer surface of the tire, resulting in raised bumps above the normal tire surface. If you do not replace the bulging tires in time, the areas with insufficient strength on the treads will most likely cause sudden bursts, and punctures are extremely prone to occur at high speeds.

5, other damage if it affects the use of tire safety can not continue to use.

Different road conditions, the vibration of the vehicle when driving is different, the vehicle has some shaking phenomenon is normal, but if the tire is due to axial displacement or the imbalance caused by the force of the jitter, we must go to the repair shop to do Check maintenance. If it is not the abnormal vibration caused by the tire, you should also pay attention to troubleshooting as soon as possible, because the long-term excessive vibration and jitter will impair the performance of the tire.

Second, what factors will accelerate tire wear?

1. If you experience some bad road conditions, tires wear faster than on flat roads.

2. If you drive violently, sudden acceleration and accelerated braking will also accelerate tire wear.

3. Routine maintenance will also have a significant impact on the service life of the tires, such as four-wheel alignment of vehicles that are too frequent, periodic pressure checks, and so on.

Third, how to judge the tire is close to failure?

In general, the tire's failure status has the following performance. Although it cannot be absolutely said that the tire has completely failed, it must be replaced as soon as possible to avoid accidents.

1, the tire surface pattern has worn out.

2. There is a flaw in the side of the tire due to impact.

3, the appearance of trachoma on the tire surface has begun to leak.

4, did not find out the reason, but the tire often loses gas.

5, although not excessively hard wounds, but the tire has been repaired several times, excessive trauma.

If the near-invalid tire is not replaced in time, resulting in a utility accident during the driving process, resulting in the loss of control of the vehicle or the anchoring of the vehicle, the consequences will be catastrophic.

The simple vehicle detection work of determining whether the tire is deformed can be completed by the owner himself.

Fourth, to regular tires to do "physical examination"

The meridian sub-tank of the tire has the function of reducing road noise, increasing friction, and distributing water. If stones are introduced into the sink, the function will be affected. Yang Ke introduced that when washing cars, it is necessary to clean the sub-tank. In everyday driving, it can also be judged from the sound of the car's over-deceleration zone. If there is abnormal sound, then there are stones in the sink, and it should be promptly removed.

In daily driving, check the surface of the tire regularly to see if there is any crack in the rubber. If you feel that the tire has a raised block, it means that there may be air in the inner layer of the tire. Regardless of whether the tire is old or new, it should be replaced; there is a fine crack on the tire tread, which means that the rubber of the tire has started to age and should be replaced.

Fifth, what kind of hazards will there be when using expired tires?

1. What is an inventory?

New tires generally refer to tires that are shipped within one year. If the tires sold to the customer leave the factory for more than one year, the “inventory tire” treatment is generally performed. The seller should tell the customer the actual production date of the tire and give a certain discount.

2. What's the difference between inventory tires and new tires?

The three-time limit for tires is three years. This time is calculated from the date of manufacture and is not calculated from the date of purchase.

If you purchase tires that were produced two years ago, you will only have one year left for the three-pack period.

Tire is a rubber product. When it is left standing for more than 3 years, the rubber may deteriorate, which may affect the safety of use.

Sixth, how to read the signs on the tires?

1. The trademarks on the tires are all marked with English letters. The trademark of the authentic tire is very clear and easy to identify. Pay attention to the tire trademark and do not buy counterfeit tires.

2. There will be four Arabic numerals on the side of the tire close to the rim, used to indicate the date of manufacture of the tire. The first two indicate the number of weeks, and the last two indicate the year. For example, 0814 means that the date of manufacture of this tire is in the 8th week of 2014.

3. When the tire is shipped from the factory, the manufacturer will post a bar code, and thus enjoy the Three Guarantees, and the corresponding manufacturers can be identified by bar codes. If there is no bar code on the tire, such a tire is easily a product of unknown channels.

4, in the tire groove will have a protruding part, if the groove wear to the protruding part, which means that the tire to the need to replace the time, to pay attention to each maintenance check.

Seven, replace the tires at least for a pair

When choosing a tire, choose branded tires to ensure quality. Regular tire rotation, because the weight of the car is not evenly distributed to all four tires, regular rotation is necessary to maintain even tire wear and maximize tire life. For four-wheel drive vehicles, it is recommended to exchange all four tires, that is, the front and rear axle tires adopt a diagonal exchange method. When the car owner stops, pay attention to keep away from the shoulder of the sidewalk, and the tire wall is most likely to be damaged. The tires used 50,000 to 60,000 kilometers. The tires should be replaced by the end of their service life. When the tire reaches a certain lifespan, the wear of the rubber is very serious, the rubber is hard and cracked easily, and then it easily causes a puncture. In fact, the use of tires is closely related to the safety of life and may result in life-threatening injuries. When changing tires, at least one pair must be replaced, because the diameter of the worn tires and the new tires will be different, which will easily cause traffic accidents.

Summary: The safety line of the tire marks the lifeline of the vehicle. If you can't treat the tire's effective use range properly, careless driving will often make the vehicle potentially dangerous.
