Generally speaking, as long as it is used under normal road conditions, not the kind of long-term driving on the road with poor conditions, the life of our tires is about 5 years, which is equivalent to about 80,000 kilometers. Of course, this is only a reference value, depending on your actual use environment, for example, in the north, the life of tires may be shorter than our central and eastern regions.
In addition, if your tires in daily use, there has been no accidental damage, no tire repair, the first 4 years of use should not have any problems, the fifth year, we better pay attention to the wear and tear of the tire, if there is no crack or missing block, that is, you can continue to use, if you are going to 4S maintenance, to the fourth and fifth year, the general after-sales will recommend you to change the tire.
In addition, you should also refer to your total mileage, if you are usually using the car more diligently, the number of kilometers driven is relatively long, an average of more than 20,000 kilometers a year, your tires must be more serious losses, it is recommended to use up to four years, the fifth year must be replaced, because some wear inside the tire you may not see, and such a high-frequency use of the car, the probability of accidents will be relatively high.
Whether your car is usually used very diligently, even if you drive thousands of kilometers a year, four or five years down is about 20,000 kilometers, then your tires can be used for more time, but remember not to exceed 8 years, whether your tires look good or not, this money do not save, pay attention to this 8-year period, not according to the time you buy the car, to calculate according to the date of the tire factory.
What about the production date of the tyre? We take the following figure as an example, what do these numbers mean, there are markings, you can see, need to mention, the last set of four digits, some manufacturers are the other way around, the first two representatives are what year, the last two representatives are the first week of production.
Let's talk about which cases, tires must be replaced, if your tires have the following problems, do not hesitate, be sure to replace in time.
Tire bulge, as the name suggests, is like us people bumped or touched, long bag, you can refer to the situation in the figure below. This kind of bulging tire has great safety risks, and may burst at any time, in the jargon of repairmen, bulging is equal to a puncture. Even if your tire does not have such a large bag, as long as you have it, replace it, don't save this money.
We judge a tire wear serious standard, is to look at the tire surface of the groove line, these groove lines can not only prevent tire slip to improve grip, but also the tire thickness of the intuitive performance, if the tire groove line is smoothed, it is equivalent to your tire is already very thin, not only grip is seriously damaged, easy to skid, but also very dangerous, may be some inconspicuous small stones can be punctured.
