Tires are very important for a car, especially in summer, level of tire pressure can directly affect driving safety. If tire pressure is too high, braking distance will be extended, and a tire burst accident will easily occur. If tire pressure is too low, friction between tire and the ground will be increased, which will increase fuel consumption and cause more severe tire wear. Therefore, car owners should pay attention to tire care during normal vehicle use, not to mention trips to 4S stores for tire cleaning, waxing, etc. In fact, these types of maintenance can be carried out independently or in conventional repairs. shops outside. and there are no problems at all. As for tires, how often should they be changed? I think this question also confused many car owners.
First, it is necessary to understand that there is no necessary relationship between replacement of tires and number of years. In other words, there is no fixed cycle, and it depends on normal use of car, driving style of car owners, and even weather and other factors. But generally speaking, most family cars need to be replaced after about 5 years, and 4S stores usually recommend that car owners change them after 3 years, but this is not really necessary. However, if life of a tire reaches 5 years, it should be replaced regardless of whether wear is severe or not, because even if durability of rubber, etc. very high, it also has longest service life. than 5 years coincides with expiration date.
In addition, if following situations occur, tires should also be replaced in advance. In first situation, tire tread pattern is very worn and cracks surrounding it are very visible, for example, when wear reaches a minimum value of 1.6 mm, tire should be replaced. Secondly, if a tire is swollen, it is better to replace it in advance. Since bulge is due to a broken cord inside sidewall, it is easy to blow through. In daily driving, when it collides with some relatively sharp objects, it is very easy to puncture, which is a great safety hazard.
Next, if tire has been punctured too many times, for example, it has been punctured more than 3 times, you should also consider changing tire. Driving on rough roads, especially after sidewall damage, is more likely to cause a blown tire. Since sidewall is thinner and force will be relatively uneven, once it is pressed against a curb or something like that and force increases instantly, tire will burst in minutes. Therefore, a clear rule on how often to change car tires does not really exist, experts also advise car owners not only to look at time, but if the above situations occur, replace them in advance.
