The life of a car tire is not fixed. Life expectancy varies depending on the environment in which it is used. Generally speaking, car tires are 3 to 10 years old, and most people can use them in 5 to 8 years. According to the driving distance, the tire life is 50,000 to 100,000 kilometers. These values are not absolute. In the good quality tires, you can also run more than 100,000 kilometers in 6 years. So, how do you know your car tires are going to be replaced?
1, normal car replacement tire time, in general, ordinary private cars generally run 10,000 to 20,000 kilometers a year. In the first five years, as long as your tires are not damaged, punctured, leaking and other abnormal phenomena, you don't have to pay too much attention. For ordinary cars, please only pay attention to whether the tire pressure is normal. The average tire pressure is between 2.2 and 2.5 bar, about 2.5 in winter and about 2.2 in summer. If you repair a tire, the life of the tire will be shortened, so it is recommended to replace it in the fifth year. The replenished tires can be driven at high speeds, but be sure to check the condition of the tires before driving at high speeds to prevent accidents. If your car hasn't been on high speeds, even with repaired tires, it can last more than 5 years. Then, use the following methods to choose the appropriate time for replacement. If the tire quality is qualified, the frequency of vehicle use is not high, and the tire will generally not be broken in the first five years of use. After five years, the driving distance will reach 50,000 to 100,000 kilometers. From the fifth year, pay attention to the use of tires, see if there are cracks, bulges, damage and other defects on the surface of the tires that affect driving safety, if there are these defects, it is recommended to replace the tires in time.
Tires have cracks In addition, it also depends on whether the tires have defects in aging and serious wear. Aging refers to the frequent occurrence of small cracks on the surface of the tire, which can also stick to the hands. Severe wear refers to excessive wear on the surface of the tire and grooved grooves on the tire. If the depth of the groove is less than 1.5 mm, the tire should be replaced. If your tires are still of good quality after 5 years of use, you can continue to use them, but it is not recommended for more than 8 years. The 8-year tire has traveled more than 150,000 kilometers, so the time has come and the life expectancy has arrived. I still have to change it.
2, the frequency of vehicle use is high, tire replacement time, some people drive a high frequency. It is possible to run 30,000 to 50,000 kilometers a year. For example, people who drive a business, people who make reservations online. That way, your tires will be almost changed in three years. At this point, the driving distance will reach 100,000 kilometers. The use time and travel distance of the tire must be considered to decide whether to replace the tire. Tire damage is used frequently, but also pay attention to the surface quality of the tire, there are the above defects or must be replaced in time. If not, exchange after 3 years.
3, the frequency of vehicle use is low, tire replacement time, some people drive with a low frequency. You can only run 3,000 to 5,000 kilometers a year. Used for 10 years, less than 50,000 kilometers. This also exists. Tires have no quality problems, normal use, from 5 years to pay attention to tire quality conditions, if the tire is still normal, 8 to 10 years can replace the tire. Tires often require the attention of the owner. What is wrong with your own car is what you know best. For example, your tire has been pricked by a nail and the tire has been repaired. It must check the surface of the tire at every high speed, paying attention to changes in tire pressure. In addition, the tire often leaks, after the air leakage is sufficient, three or five days of tire puncture, it is necessary to consider whether the tire is aging. Or is the tire broken? Because the tire is inflated enough, it will not leak even after normal use for half a year.
The tire is pierced with nails, so when changing the tire, is it four tires together, or two tires first? In general, the two front wheels of the forward car wear more severely than the rear wheels. Rear-driving is the opposite, with private cars mostly moving forward. The wear and tear referred to here refers to the wear and tear of the tire under normal use, and the tire will rub against the ground when driving. Tire wear can be seen by the depth of the surface groove.
If you need to change the tire, there are two options: 1, the front tire that is badly worn 2 to replace the new tire, and the rear wheel should not be replaced first. This method is relatively economical. The money for two tires and the money for four tires doubled. Replace the front wheel when the front wheel is badly worn, and the rear wheel continues to be used. After a year or two, the rear wheels can also be replaced. When replacing the rear wheels, you can remove the front wheels and install them on the rear wheels, and then install the new tires on the rear wheels instead of directly replacing the new tires with the rear wheels. The reason why the tire has cracks is that the front wheel is seriously worn and the drive wheel is the driving wheel, so the new tire is preferred to the front wheel is safer. This is true every time the tires are changed. The danger of punctures at the front wheels is far greater than that of the rear wheels, and the front wheels are relatively safe to use the latest tires. Changing a tire must be a dynamic balance, and the price of the dynamic balance is between 10 and 20 yuan per tire.
2, 4 tires all changed at once. Of course, all four wheels can also be replaced at once. There is no problem in doing so. Just need money. Compared with the method of replacing two tires first, replacing four tires at once is more convenient and reducing the balance of movement at one time. Even if you change two tires first, you have to change the other two after a year or two. I just extended the amount of time I spent. And the front wheels had to be removed and replaced with the rear wheels. In addition, it must be modified and replaced twice. Manpower is needed here. If you change all four tires at once, the cost is very high. My car was troublesome at the time, but in the sixth year I changed four tires at a time. This is called a step.
Anyway, the car that changed the tire once was driven for another four or five years, and the car has been driving for more than ten years. I'm not going to change the tyres a third time. It was a transfer at that time. It is not recommended to change one tire at a time. Either two tires each or four tires each. If only one tire is replaced, the left side is the new tire, the right side is the old tire, the height is different, it will affect the driving feeling, and the fuel consumption will also increase.
