It is difficult to rectify the problem of tire safety due to traffic safety

It is understood that in this year's issue of product complaints, the quality of important parts and components of automotive products still occupies the vast majority of the quality of the problem, the user's attention to safety has increased significantly, in typical complaints, complaints about the quality of tires are more prominent . According to industry insiders, "The complaints about tires have indeed increased over the past year or two." The reporter recently found that the latest question of tire quality is still an "old problem."

Old problem

"My car is equipped with Kumho tyres and opened less than 10,000 kilometers. Four tyres bulged at different levels. I called the 4S store. They said that this is a problem for Kumho tyres. It does not matter to them. I went to the tire company to test it. However, at the inspection center, the inspectors said that they did not belong to the quality problem when they looked at the tire because I was driving improperly and hit the drum kit.”

Mr. Ke of Wenzhou purchased an Excelle car at the price of 118,000 yuan at the Wenzhou Excelsior 4S shop on March 7 this year. The Kumho tires are assembled in 4 wheels and the tire size is 195/55/15. After 3 months of use, bulging occurs on the left rear tire of the vehicle, which affects the normal driving and personal safety of the vehicle. Mr. Ke’s friend subsequently negotiated with the 4S shop. The other party stated that Mr. Ke’s improper use had caused this result and refused to change it. In desperation, Mr. Ke had to replace the same model of Kumho tyres at a tyre shop. After 3 months of use, the tires showed a slight bulge again, and the left front wheel began to bulge.

Mr. Ke told reporters that since he bought the Excelle, most of the time he used to work, between the suburbs and the urban area, an average of 20 kilometers per day, this section of the road is very good, all asphalt, no bumps, There was no case of violent impact on the tire.

According to him, many of his Wenzhou Excelle Che Youhui have this situation.

Mr. Ke asked Kumho Tire to give him a statement and compensate him for his losses. However, his request has not yet received a reply from the manufacturer.

New answer

According to the reporter’s understanding, many users have negotiated with distributors after similar issues such as drum kits, and most of the final results are nothing. As an important part of a car, the quality of tires is directly related to traffic safety.

According to the survey, the actual life span of Chinese automobile tires is less than 30% of the normal life span; 38% of the tire crowns have nails or punctures; 36% of the tires have cuts, scratches, cracks, etc.; 21% Tire aging needs to be replaced in time; 17% of tires suffer from abortion and eccentric wear, and four-wheel alignment must be done; 11% of the tires are seriously damaged and the bag must be bagged. The problem with tires is that the possibility of a puncture accident is very high, the general driving is dangerous, and it is no longer possible to run at high speeds. The tire must be replaced immediately. But until they are detected, consumers are still ignorant about the safety hazards of the tires.

According to another survey, 34% of the vehicles had not checked the tires before long-distance or highway access; 52% of car consumers did not know the brand and model of tires used in the cars they were driving; more than 60% Car consumers are not clear about the harm caused by abnormal tire pressure. In all tests, only 9% of tires did not have any problems.

Tires on automobiles require high mechanical strength. After long-term use, due to wear, aging, fatigue and mechanical damage, its mechanical performance has been greatly reduced, can not meet the needs of high-speed vehicles, it will suddenly burst tires at high speeds, prone to major traffic accidents, the consequences are terrible. According to the statistical data of safe traffic management departments across the country, according to statistics from the safe traffic management departments across the country, 46% of the traffic accidents on the expressway are caused by tire failures, of which punctures account for 70% of the total accidents. 46% of all traffic accidents on the highway are due to tire failures, of which punctures account for 70% of total accidents.

As mentioned above, Mr. Ke’s tyre bulging problem is very likely to cause traffic accidents if the vehicle is driving at high speed. So is his tyre bulging a quality issue?

It is understood that in the tire production process, there are many factors that may lead to quality problems in individual batches. Once there is a problem, there is no perfect "recall" "three guarantees" system to protect the rights of car owners. Although more and more car owners have realized this, but the quality of the tire itself is too much in the end, and there are doubts, it is even more difficult to find solid evidence.

A consumer told reporters: "Some tire companies know that quality assurance requires a lot of costs, and many places have no way to do identification, they simply kick the ball to the consumer, so that consumers have difficulty retreating, nothing. "Obviously, this is not a mature business practice. It is understood that the replacement cost of a tire is about 400 yuan, but the replacement of four is only 1,600 yuan, and the cost of testing once reaches 2000-3,000 yuan. By comparison, consumers can only bear the replacement cost themselves. In the fight between consumers and distributors, the quality of tires is a real problem for both parties.

How to control the quality of the product in the end, whether the quality of each batch can meet the standard?

According to experts from the China Rubber Industry Association, “The abnormality of tires poses a great safety risk. If the tires are bulged, it may cause a sudden puncture during high-speed driving, causing the vehicle to get out of control and even causing a tragic accident. Therefore, it will be used in tire testing. Special attention is paid to the fact that if an ordinary company follows the prescribed procedure, professionals will test it from the semi-finished product stage. If the tyres appear in large quantities, the drums are largely caused by quality problems. The quality system of the company may be Something went wrong."

According to exquisite tire technology professionals, said: "In the quality of the tire before the factory inspection, dozens of procedures to guard, from the beginning of the refining process, plastic parts preparation, extrusion, rolling, to the tire molding, vulcanization, and finally After the inspection inspection process, more stringent quality inspection procedures will be developed. After the tires are officially put into production, tire testing will continue to monitor the quality of the tires. These tests are the same as those performed when releasing new tires. of."

Reflection

According to reports, tires are divided into full-standard tires, pin-standard tires, and standard tires. Full-tire tires are produced by tire manufacturing companies. The tires are tested by the company's quality inspection department against the corresponding national or corporate standards. Tires that meet the standards. There are no guarantees for the quality of tires that have been painted or scribed. There are two kinds of tires for the marked tires: one is that the tire factory quality inspectors detect the defects affecting the service life from the production line through the inspection procedure according to the inspection procedure, and do not meet the relevant standards, but still have certain use value of the tire; The other is an inventory overstock tire with a production date of more than two years or three years. The marked tire is called as a by-product tire or a defective tire in the factory. The factory generally deals with the price reduction to the dealer and is not responsible for the after-sales service.

Shandong Linglong Tire Technology Researcher told reporters: "For each batch of tires from the production process to the factory before the last inspection, they strictly control the quality, strict quality of each batch of factory tires."

In fact, according to the relevant regulations of the industry, the normal service life of ordinary tires is 3-5 years from the date of delivery. If during this period, bulge is not caused by special reasons such as collision, the quality of the tire may be problematic.

At present, Kumho Tire Co., Ltd. is already the world's ninth-largest tire company and has implemented tire support for dozens of domestic automobile manufacturers, including FAW-Volkswagen, Shanghai GM, Changan Ford, Beijing Hyundai, Dongfeng Yueda Kia, and Dongfeng Citroen. Manufacturers, tires supporting more than 6 million per year. Unlike the current domestic tire retail market that lacks a complete set of tire quality monitoring systems, the quality requirements of the supporting market are relatively strict. In order to become an accessory manufacturer of a complete vehicle manufacturer, it is necessary to go through the inspection and inspection of multiple complicated procedures. Such a large area of ​​tires hidden danger of the tire is how to pass the vehicle manufacturer's testing, vehicle manufacturers to detect the existence of certain loopholes in the quality of tires, this issue is also worth thinking of vehicle manufacturers.

For consumers, there is a problem with one of the four tires. The probability of this problem has reached 25%. If it is a batch problem and the quality of each batch cannot be controlled, it may be affected. The wheels will be tens.

To succeed, enterprises must first earnestly respect, good attitude, and service in quality. Perfunctory consumer behavior is actually perfunctory.

For enterprises, when they find that their products have the same type of problems in large quantities, the first thing to do is to check and correct themselves. This is not only responsible for consumers, but also a good opportunity to improve product quality and corporate reputation.
