As we all know, the tire pressure changes with the change of temperature, and the tire pressure will be adequate in winter. If the tire pressure is insufficient, it is likely to cause a blowout. In general, the risk of gas blowout is higher, if the tire continues to run when the tire is lost, the tire side wall will be deformed, the driving time is long, and the inside of the tire will accumulate a large amount of heat, and the heat will eventually lead to the change of the internal pressure of the tires, thus triggering the tire. It is reported that tire blowout caused by tire blowout accounts for almost half of the tire blowout, so it is suggested that the owner must form a good habit of regularly checking the tire pressure at regular intervals. The owner can purchase a tire pressure monitor and monitor it every one or two weeks. It can also see the tire pressure frequently and see whether the tire is defective or not. The most reliable way is to go to 4S shop every half month or a month to check once. Some owners think that the tires can be used as long as they are not bad. In fact, it is not, the tire has a life span, and if the tire is overdue, it can not continue to use. Under normal circumstances, the service life of tires in 2 years ~3 years or about 60 thousand kilometers, more than service life or have serious wear tire should be replaced in time. It is reported that the shelf life of rubber is generally about 5 years, and the service life of the tire is closely related to the use of methods and storage conditions. Therefore, the car pays close attention to its own tires. Once the tire is found to have aging, accidents and serious wear and tear should be replaced. The so-called "wound" tire usually refers to the hole in the sidewall of the tire. The car owner's road is more complex in the daily driving, so the phenomenon of tying is unavoidable. The tire tie is usually a frontal hole that can be repaired, and it can be used normally, but it can not be repaired if the sidewall of the tire or the sidewall of the tire and the angle of the tire face can not be repaired, even if it is repaired. Often check whether the tire is damaged in daily traffic, such as whether the surface of the tire can be nailed, cut and so on. Once the damage is found, it should be repaired or replaced in time. If it is found that there are some stones in the tread groove, it should also be removed in time to avoid tire crown deformation. Also, do not let tyres contact with oils and chemicals. Every time a tire runs, it needs to be transposition so that the tire can be evenly distributed. Every 5000 kilometers of the vehicle should be replaced by a tire, four kilometers per 5000 km to 10 thousand km to avoid abnormal wear. It is not allowed to install different models or new and old differential tyres on the same shaft. When the wheel imbalance is beyond the standard, the high frequency oscillation will occur when running at high speed, causing the tire to wear out, which is not good for driving safety. After tire repair, action should be taken to balance detection and adjustment. The tire unilateral dynamic balance should be less than or equal to 40 grams.
