1 What are the tire puncture signals? During the Mid-Autumn Festival, the hottest news in the automobile circle was the incident involving the Land Rover Range Rover explosion. On August 30th, a Range Rover Range Rover exploded in Sanhe, Hebei, and the live surveillance video was also spread online. However, on the 16th, Hebei Province Sanhe police released the investigation results, saying that the explosion was caused by a flat tire and no suspicious attachments or smoke traces were found on the vehicle. After the survey results were published, it immediately caused a lot of questions on the Internet. â— Review of the incident: The vehicle exploded at the start and the power was higher At the crossroads of the incident, surveillance cameras photographed the events and we can feel the power of the explosion from the following live video: [Monitor real shot: Land Rover car suddenly exploded while driving and the door panel was blown away a few meters away] According to the police investigation report, the explosion of the left front wheel of the explosion vehicle was triggered; while the owner Liu said in an interview, the left front wheel of the puncture was replaced by a spare tire. Two days before the accident, the left front tire leaked and replaced the spare tire temporarily. This spare tire was an old tire two years ago. It has never been used. After replacing it, there was a warning message in the interior system. Maintenance, replacement, until the accident. At that time, the car was driven by a friend Zhang and he was sitting in the assistant driver's seat. When the explosion occurred, he was only shocked by the ear. It did not matter. The driver Zhang suffered a broken leg and the scene was bleeding. â— Pay attention to the "signal" that tires need to be replaced Although the investigation results of the police are controversial, this article is not intended to evaluate the results of the investigation. Instead, it is based on the conclusions of the police to see if there are any hidden dangers. In fact, in many cases of punctures in the past, the power is also very different, and the consequences will be more serious. Therefore, we urge you to “look at the excitement of your friendsâ€. We should pay more attention to how to avoid the occurrence of flat tires. When there is a hidden danger in the tire, there are often various "signals" to remind users to pay attention: 1, tread loss close to wear marks Any brand of tire will have a wear mark on the bottom of the tread groove. The wear mark height of a typical car tire is 1.6 mm (this height is also the legal minimum groove depth of the tire), and the wear mark height on the load tire is 2.4 mm. Some owners think that as long as the tires are not broken, even if the tire treads are worn out, they will continue to be used. Such old tires are actually very dangerous: when it meets a slippery surface, the tread pattern cannot completely drain the water under the tires. , it is easy to cause the vehicle to lose control. 2, tire cracks or bulges and other damage In the course of daily car use, tires may be caught by foreign objects or accidentally hit the road, which can lead to tire damage. Damaged tires include cracks in the tread, bulging of the tread, loss of the tread rubber, serious wear of the sidewalls, and multiple tires being caught by foreign matter. Especially the bulge, the tire will have the danger of bursting at any time. As long as the tires are found to have these damages, the owner will have to go to a professional tire store as soon as possible to check the car's tires and replace them in time. What is a cord? The cord is a warp thread material for woven cords, and is also used as a reinforcing material for rubber products such as tires, conveyor belts, and transmission belts, and is mainly applied to tires. The material of the cord is cotton yarn, viscose fiber, polyamide fiber, polyvinyl alcohol fiber, glass fiber, aramid fiber, and steel wire, and their properties are different. Different types of automobile tires will select cords of different materials according to performance requirements and cost factors. 3, the expiration of the age of the tire Even if the car owners usually drive cars, how good the road conditions are, how tire maintenance is in place, and the tires are used for a long time, they will gradually age. The service life of a tire is usually about 5 years, beyond which the tire will begin to age. The main performance of tire aging is surface hardening, followed by cracking. Aging tires lose their elasticity. Continued use will cause tread deformation and risk of puncture. Therefore, even if the aging tires do not seem to have serious wear, the owner must also be vigilant. The most reliable approach is to go to a professional tire shop to check the condition of the tires to determine whether to replace the new tires. 2 How to make the tire more durable? â— How to make the tire more durable? After a poor quality tire is a small probability event, if the tire is damaged, the owner should first review their own car. As long as the owners develop a good habit of using cars, they can greatly improve the service life of the tires. 1, to avoid the original direction Due to poor car feel, many novices like to play in the same direction. This bad habit is basically brought out from the driving school. The direction of in-situ driving will cause the wear of the tires to be concentrated on the same contact surface, causing severe tire wear locally and shortening the service life. Therefore, the owner should avoid in-situ direction, but should be in the direction of the tire when rolling, so that the ground brings the tire is full and uniform normal wear. 2, avoid hitting the shoulder and into the pit Some car owners have more domineering parking methods. They like to park their cars on the shoulders. During the ride on the shoulder of the vehicle, the tire will be squeezed, which will easily lead to the breakage of the cord on the side of the tire and cause the tire to bulge. Holes in the pavement should also be avoided. When the tires run over the pit, the tires will also be squeezed. The bigger the pothole and the higher the speed, the more the tires will be squeezed. This will also cause the tire to bulge. 3, avoid abortion wall In many cases, the abortion wall is inadvertently caused when the vehicle is pulled over. It may be that the owner of the car is not in a good sense, or the owner may be deserted. The side of the tire belongs to the weak part of the tire. If the tire is worn badly, it will cause the tire to bulge and bring about the danger of a flat tire. Therefore, when the vehicle owner is parking by the side, he should pay more attention to the distance between the vehicle and the shoulder and avoid aborting the wall. 4, to maintain a proper tire pressure Proper tire pressure can ensure that the tire has a uniform ground contact area and reduces unnecessary wear. Therefore, the owner should develop the habit of regularly testing the tire pressure and keep abreast of the tire pressure conditions. Test tire pressure can go to a professional repair shop, you can also buy tire gauges to test their own tire pressure standards can refer to the vehicle tire pressure label. 5. Exchange four tires according to tire wear Many owners know that tires need to be swapped regularly to ensure that the wear levels of the four tires are as consistent as possible. So how should we swap positions? Many people think that four tires are interchangeable positions, that is, left front, rear right, rear right, front left, and back, but in fact this is not correct. Since the load on the front and rear axles of the vehicle is not the same, in order to allow the four tires to wear evenly and prolong their service life, we suggest that the owners interchange the positions of four tires every 8,000 or 10,000 kilometers. The following principles must be followed when changing the tire position: The drive wheel is changed vertically, for example, from left front to left rear; the non-drive wheel is changed diagonally, such as right rear to front left. Rear drive is the same principle. If it is a four-wheel drive model or a single-guided tire, it is straight forward and backward change, such as the left front to the rear, the front right to the rear. Summary: The Land Rover explosion this time, the police announced the results of the puncture. We do not discuss whether the results of this survey are tenable, but should care about how to avoid the occurrence of a flat tire. Tire puncture hidden danger is actually there will be a variety of "signals" in advance to inform owners, we usually have to develop the habit of checking tires, correct incorrect habits of the car - I believe no one is willing to burst with this The headline of the way of the fetus.
