With the economic development of our country, automobiles have become a means of transport for many people. However, tires are one of the most important parts of the car and have important significance for driving safety. Therefore, how to increase the service life of automobile tires has become an important issue. What problems should be paid attention to when using tires? Today, we will give everyone a general knowledge of this area.
It is common to exceed the useful life of the tire. The phenomenon of over-age service of automobile tires is very common. A maintenance staff pointed out that more and more tire service age. The tires of a car owner have been used for ten years and have not been replaced in time.
According to random interviews with 10 drivers aged over five years, six owners indicated that they had not changed their tires temporarily. Two of the owner’s tires had been in service for more than seven years. The reason for not changing was that the wear was not serious. The three owners indicated that they had changed tires within five years. The other owner said that the tires were not worn out so they did not pay attention.
The survey found that as more and more cars play the role of family cars, most of the vehicles travel around 10,000 kilometers per year. With the current good road conditions in the urban areas, most vehicle tires wear after 5 years of use. Nor is it serious.
Maintenance personnel who are unwilling to be named indicate that there is a long-term lack of trust between car owners and maintenance personnel. If the tire does not have obvious cracks or wear, it is very difficult for the maintenance staff to persuade the owner to change the tires, and the owner of the vehicle will remind the maintenance staff of the good intentions and become a means of profit for the repair shop. In addition, some owners save money, and even if the tire's sidewall is pierced, it still insists on repairing the tire without changing tires.
According to statistics, some people in the industry pointed out that although there is no report on the service of over-ageing of tires at the moment, the phenomenon that tires are out of service is definitely not the case. The number of old cars over 5 years old exceeds 500,000. In this huge army of vehicles, there are bound to be many older owners of tires in service.
Lack of useful life guidelines for tires
The investigation found that the current service age of automobile tires is mainly due to the current lack of authoritative guidelines on the service life of tires. At present, there is no official authority for the use of tires. This reporter learned that the current tire company's general recommended life span is 3 to 5 years, according to "wear and tear" in the life of the replacement.
The tires are more chaotic in terms of shelf life. The shelf life provided by 4S stores and car companies is generally only 3 months or 5,000 kilometers, while the shelf life provided by tire manufacturers is usually 3 years. At present, we can inquire about the use of tires, only in the “Tire Distribution Business Practices†specified three-year period for tires.
Local auto repair experts pointed out that tires, which are very important as they affect vehicle safety, have not been issued in time with relevant guidelines for use. This obviously does not match the current car environment. The introduction of the guidelines for the use of tires allows more owners to correctly understand the importance of the tire's useful life.
5 years should change the watershed
It is reported that the current use of radial tires with higher safety margins is generally used in cars. In the normal use of tires, the probability of bursting tires is not large. Dong Shaofeng pointed out that there are two major problems in the breakdown of automobile tires, such as air leakage and tire blasting. The process of air leakage is generally slow, causing little harm to accidents or even causing casualties.
The consequences of accidents caused by a blast of tires are generally severe. In particular, high-speed tire blasts are very lethal, and they can even kill a car. In the case of a tire-bursting accident, it is often the case that tires have hidden dangers and they appear under strong external forces. Unless there is a strong external force, if there is no safety hazard and tire pressure is stable, the tire will have a very low risk of tire explosion.
A professional analysis, the current tire inflation equipment has been very advanced, there are generally tire pressure guidelines, coupled with the inflator is generally responsible for the professional auto repair personnel, tire tire pressure is too low phenomenon rarely occurs. Second, the tires run on a normal road surface. There is a steel chain on the surface of the tire that touches the ground. The risk of a crash caused by pressure is less likely.
On the premise of good tyre performance, the weak tyre wall has sufficient bearing capacity. The phenomenon most likely to cause a tire blast is mainly the aging of the rubber or the part of the tire wall that has been pierced by a hard object.
Numerous maintenance personnel pointed out that due to the aging of tires, it is recommended that the tire replacement cycle be 5 years. Because of the difference in the use environment, the tire replacement first looks at the wear, followed by the age limit. If it is worn out, it needs to be replaced even if it is used only for one year. However, tire wear is not obvious, and tires that have been in service for more than five years must also be replaced. Otherwise, it is easy to have a risk of tire explosion.
I hope that after reading this article, you will have a correct understanding of the tires. Don't take the mentality of the small things and eventually lose out .
