Maximum service life of tire 10 year? It's not as simple as you think. Tell me about your own experience.

If you have some car experience, you should know that tires are very important and there is too much noise inside the car. You don't have to spend a lot of money to upgrade the sealing material, and you don't have to spend a lot of money to upgrade the sound insulation. Just change a silent tire and the whole world will be quiet!

But speaking of it, good tires are expensive. The price of high-end models of first-line brands such as Michelin, Mapai and Bridgestone is at least several hundred. If it's an SUV tire, it's not unusual to have more than 1000 tires, but the tires are fragile and will be scrapped in minutes, and the auto insurance will not be paid (unless you know insurance very well), and hundreds of thousands will be wasted.

Even if we are lucky, we will change the tires one day and the money we should spend will not escape. In fact, most people have no special requirements for tires, but they are durable, fuel-efficient and cheap. However, after looking at a circle of tires, they will find that there seems to be no accurate durability figure. In other words, the durability of tires depends on evaluation. ? Because tire manufacturers don't indicate the service life of their tires, most people don't know what the durability standard is, and they don't know how often to change tires under normal use. ? Expensive is not necessarily wear-resistant? Interpretation of tire wear index? Why don't tire manufacturers indicate the relevant data of service life? Because the service life of tires is mainly affected by environmental factors, such as high temperature will shorten the service life of tires, combined with specific road conditions, the service life will become more complicated, so manufacturers can not give a specific number, such as mileage and service time. In all fairness, if the tires are properly maintained and rarely used, I am afraid that when the car is sold, the tires will still be good.

In order to let consumers have an intuitive data to refer to, the Highway Safety Administration of the United States has formulated a mandatory standard of unified tire quality rating (UTQG), which means that tires sold in the market must have this rating label, which will be printed in an inconspicuous position on the tire wall. People usually call it 3T index.

3T refers to traction, temperature and tread wear, among which the testing method of wear resistance index is not complicated, that is, the tire to be tested is put together with another standard tire for lateral comparison, and after driving1.2000 km under the same road conditions, the tread wear difference between the tire to be tested and the standard tire is measured.

If the wear resistance index is 400, its wear resistance is twice that of 200, which can be understood as more durable. The friction coefficient of durable and fuel-efficient tires is not high, that is, the grip performance is not strong, while the tread of tires with high wear resistance index is hard and the tread of tires with low wear resistance index is soft, so performance tires are often not wear-resistant. ? Different brands can't be generalized? What's the difference between wear resistance index and service environment? Wear index, like the fuel consumption of the Ministry of Industry and Information Technology, is the test data obtained in a fixed ideal environment. In reality, everyone's driving habits are different, and the environment inside the car is also different. These variables make it difficult for tire manufacturers to accurately calculate the service life.

Wear index is also easy to misunderstand, that is, the service life of tires can be compared only by looking at the index. Why do you want to overturn the previous view? Because it has been said that there is a benchmark tire for the wear index test, but this benchmark tire is always changing, and laws and regulations do not require every enterprise to mark rigorous and accurate data, and the wear index limit standards of different brands of tires are different, so the wear index of different brands of tires cannot be used as a reference. ? In other words, the tire wear index of the same brand can be used as a reference, and a high value means more durability, but the data comparison between different brands of tires is meaningless. ? Tires need maintenance, too? How to prolong the service life of tires? Tire maintenance is not to spray some wax at the car wash shop to make it look shiny, but to check the tire pressure frequently, adjust the four-wheel alignment according to the situation and change the tires as required to make each tire wear evenly.

Whether the frequency of car use is high or low, tires will age. There are many kinds of aging, such as cracking and hardening. In this case, the tire needs to be replaced. According to some tire manufacturers, even if there is no physical damage, tires need to be replaced in 6- 10 years, which means that the final service life of some tires can reach 10 years. ? Although domestic tires are not expensive, most of them are durable, and the comprehensive performance of international first-line brands is excellent, but only a few of them are optimized for domestic road conditions, so the wear-resistant advantage is not obvious, let alone the high price. Tires are related to driving safety, and necessary inspection and maintenance are indispensable.
