How long do car tires last?

The life of a tyre is related to many factors, such as climate, road, driving style, installation, maintenance and repair. According to international regulations, if the tire is used normally, the tire must be replaced when it is ground to a tread depth of millimeters.

Regular tires are valid for five years after production, so we recommend that you have to replace them after four to five years of use, regardless of whether they are worn to the millimeter. At present, there are no clear regulations on the wear and tear of tires in China, and the above suggestions are based on European regulations. In addition, if a tyre fails, such as a cut on the sidewall, it must be replaced immediately.

What factors can determine the life of a tire?

The first: tire pressure and load.

The tire pressure of this tire, if it is lower than your standard normal tire pressure.

20%, basically it will be reduced.

Arrive. This mileage is a 20% discount on life. That if the tire pressure is higher than normal.

20% of the words, that's less.

The mileage is seven or eight folds. If it is a load, our driving license and factory nameplate will write this approved load weight, if it is overloaded.

20%, then the life span basically starts directly at seven folds. Therefore, the pressure of the tires and the weight of the things we load really have a little impact on the life of our tires.

The second: speed and temperature.

For example, a tire can reach a speed of 65 per hour

At kilometer per hour, its lifetime is 100%, and the temperature is 19. So if this speed is increased to 110

kilometers per hour, under the condition that the temperature remains unchanged, the life is directly 55%, a decrease of 45%.

That's just the analogy of speed, if you are twice as fast, the life of your tires is basically cut in half. So from another point of view, from the perspective of temperature, for example, a certain tire, its speed standard is.

kilometers per hour, at 4 hours, it grinds and grinds, and if it is on the ground, it can grind off 100

grams of rubber. But if this temperature is raised to 30, the same way is opened, 80

kilometers per hour, you have to grind off this 300

grams of tire rubber, that is basically nearly 3 times the amount of wear. So we can see that the most important thing is naturally the tire pressure of our tires and the weight of our load. Then, in the temperature and speed, the wear and tear consumption of the tire by temperature is more obvious than that at this speed, one is cut in half, and the other is directly turned.

times this consumption, then only.

The average tire can be used for 3-5 years. You can check the wear of the tire tread and stop using it when the tire tread is worn to the limit mark, i.e. the tread depth is less than millimeters.

Tires are generally replaced, wipe and change, as for the lifespan, generally you may change it in five to six years, of course, drive less, the road conditions are good, and it is not impossible to take a long time. Taking all-season tires as an example, according to Consumer Reports, the average all-season tire can travel 110,000 kilometers. For China's roads, running 90,000 kilometers, that is, changing every year, seems to be no problem.

How can you tell if your tires are polished? In this regard, China has a mandatory legal requirement: the surface tread wear of tires should be lower than the wear mark, that is, almost 1 in value.

At 6 mm, it's time to replace. If you really get to this time, you don't have many tires and light tires, and there is a certain degree of degradation in terms of safety performance, drainage performance and grip, etc., it is best to leave a certain margin for your tires, such as about 3 mm, and you can consider replacing tires. It has been reported that Mr. Zhao, a consumer in Heilongjiang, bought a car in July last year, and in April this year, he found that the 4 tires assembled by the original car were bulging and cracking, and found the 4S shop and the vehicle manufacturer, and the answer was that the warranty period had expired.

According to Mr. Zhao, in fact, he replaced the snow tires in November last year as soon as the winter began, and until March this year, the original car tires were used for more than 4 months, and this year just changed for more than half a month, and there was a problem that 4 tires only bulged. At the end of March, 28 provincial and municipal consumer associations (consumer associations and consumer protection committees) jointly conducted a large-scale survey on the after-sales service policies of 12 tire brands, including Michelin, Bridgestone, Goodyear, Kumho, Dunlop, Hankook, Yokoma, Continental, Pirelli, Cooper, Jitong and Toyo.

The survey found that the top companies in the market not only have different warranty periods, but also the warranty period and compensation period of many tires are calculated from the date of production, with the shortest being three years and the longest being five years. In other words, if the inventory time is short, the consumer enjoys a longer warranty period; Conversely, if the tires are stocked for a long time, the warranty period enjoyed by the consumer will be shortened accordingly.

When tires that have been in stock for more than two years are bought by consumers, it is difficult for consumers to enjoy various compensation rights during the warranty period.

Generally speaking, car tires can be used for up to 5 or 6 years if they are used in normal ways, and if they exceed this age, the car will have certain risks during driving, and it is recommended to replace the tires in time.

Generally speaking, the service life of car tires is about 6 years, and the tires can be replaced when they reach 110,000 kilometers, depending on the degree of wear and tear of the tires.

Under normal circumstances, the service life is 5 or 6 years, if the driving time is more, and the road condition is not very good, then the loss will be more serious, less than 5 years to replace, but also less than half a year or a year for tire maintenance.
