People who understand the common sense of tires will say that it depends on the tire pattern wear, in fact, it is this theory, every car's tires have tire wear indicator mark, if wear to a certain extent, then change the tire is imperative. Decorative pattern on the surface of the tyre wear our rules and regulations must be changed to 1.6 mm, but in actual driving, if true to this extent, the performance of the tire becomes poor, grip and drainage ability will become worse, and security will be less, so foreign tire experts said, tire to retain at least more than 3 mm in order to be safe. If the mileage to calculate, the United States last year had a test report showed that the more common four seasons tire mileage is generally more than 113,000 km, if the tire can run a little less than 100,000 km, if in order to ensure safety, it is absolutely no problem to run 80,000 km.

In terms of wear and tear, the life of tires can reach tens of thousands of kilometers or even 200,000 kilometers. But the average tire lasts only half the life of a car. Tire wear is related to a key, brake distance! So generally in the pattern eat half of the people began to change the tire, and because of a few years down, the elasticity of the rubber began to weaken, so, in order to 200% of the safety then basically began to change the tire. Comprehensive consideration, private car tire change time is also an indicator of how many holes. If punctured 3 above, also can change actually, especially the tire that side wall gets hurt. Really to grind tens of thousands of kilometers of tires, private cars are basically scrapped. Generally, private cars cover a distance of 20,000-30,000 kilometers a year, and some people who love cars drive 10,000 kilometers a year. Therefore, the tire wear of private cars is very little, are changed with time. You can change tires in 7-8 years. If 10 years, run city highway only problem is not big. Different brands of tires, their service life is different. Generally master the principle of tire life is: normal life in 5 years or so, which is determined by the quality of the tire, to the year tire aging cracking, bearing capacity decline, easy to burst tires; In the normal use of life, as long as the tire wear to the wheel gear groove raised mark must be replaced, or ibid also endanger driving safety.

If you often drive on the road, the road condition is normal or good, drive about 150,000 km will be replaced; If you often drive on bumpy gravel or mud roads, you may drive 80,000-100,000km or so. But still want to regularly check the tire wear degree, mainly to see the tire tooth mark depth, the tire change, the tooth mark is probably only 5-10mm deep on the change.

Current tire inflation equipment has been very advanced, there are generally tire pressure guidelines, and inflation is generally responsible for the professional auto repair personnel, tire tire pressure too high phenomenon rarely occurs. Second, the tires run on the normal road surface, contact with the surface of the tire steel chain, pressure collision caused by the possibility of blowing up is less. Under the premise of good tire performance, the weak tire wall has enough bearing capacity. And the phenomenon that causes blow-out most easily, basically be the tire wall part that rubber ages or once was punctured by hard thing.

At the same time, it should be noted that private car tires have nothing to do with mileage, but only with time. If basically park in the open parking lot, 4 years will consider changing a tire. If parked in the garage, 6 years also need to replace, because the tread rubber has aged. Any time you find a small crack on the side of a tire, change the tire immediately. So how many years do tires last? In fact, this depends on the specific mileage of each car, if it is a year to drive also about 10,000 kilometers, that will not need to be replaced until 7 or 8 years later.

The service life of additional tire is to have very big concern with the use environment of the car actually, for example climate, car runs and parking environment, and the driving habit of car owner can affect the service life of car tire! Countries did not explicitly stipulated in the service life of tires, and tire brand and car companies are also different versions, such as nissan and Mercedes will prompt the owner change a tire, 6 years and for Michelin and some domestic brands, said its production tire life up to 10 years, but they also prompt the owner use five years later, a year have to be a professional inspection of tyre, in order to ensure their safety. Many maintenance personnel pointed out that the impact of tire aging, recommended tire replacement cycle for 5 years. Because of different use environment, tire replacement first wear, and then look at the number of years. If wear and tear, even if only a year of use, also need to replace. And in the tire wear is not obvious, more than 5 years of service tires must be replaced, otherwise prone to the risk of blowout.
