When the tire needs to be replaced
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 not possible to think about how long it takes to change the tires. 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, the use of expired tires will have what kind of harm?
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.
Fifth, 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.
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.
