What circumstances need to change car tires
According to the tire wear, according to the tire shelf life: the tire will have four digits on the side of the tires indicate the date of manufacture of the tire, the first two representatives of the number of weeks, the last two representatives of the year. The use of tires generally do not exceed three years, mileage of not more than 60,000 km. Although slightly over the years and mileage also hinder the overall situation, but the winter low temperature and summer rain will make the tire wetlands grip and dry handling "stretched." More attention to the side wall: With the gradual aging of tire rubber, tire sidewalls will appear deep lines. But as long as the tire sidewall without impact, the cord is not broken, you can continue to use. The triangular mark on the sidewall of the tire can help the owner find a protrusion in the groove of the crown, and determine the actual wear limit of the tire, which should be greater than 1.6 mm.
The first point: If the tires are aging (for example, there are countless small cracks in the tread or tread of the tread that are about to hurt the carcass), it is necessary to replace the tire in time, no matter how long the tire is used and how much How many of the second points: If the depth of the tire trench is at or below 1.6 mm (the tire tread longitudinal straight groove has an indication mark indicating the depth), the tire must be replaced because the tire's drainage capacity Greatly reduced, the vehicle will be more dangerous in the wetlands. In addition, the damaged tires should also pay attention to whether the need for replacement, such as the lack of rolling tires can still run in the inflatable state, but because the tire internal structure may have been damaged, it is recommended to replace the new tire The In particular, it should be reminded that drum tires can not continue to use.
There are three cases where you can change the tires: 1, tread loss close to the wear mark. Any brand of tires will be set in the tread groove at the bottom of a wear mark. General car tires wear a mark of height of 1.6 mm (this height is also the minimum tire trench depth), the load on the tire wear mark height of 2.4 mm. 2, the tire cracks or drums and other damage in the process of daily cars, tires or foreign body will be tied to, or accidentally hit the road teeth, which will lead to damage to the tire. Tire damage situation, including tread cracks, tread drums, tread rubber missing, serious sidewall wear, tires repeatedly been foreign body and so on. Especially drums, tires at any time there will be the risk of bursting. As long as the tire appears to be damaged, the owner as soon as possible to the professional tire shop to check the car's tires, timely replacement. 3, the tire life expires. Even if the owner of the usual driving how the gentle, how good the road, how to maintain the tire in place, the tire is used for a long time, it will gradually aging. Tire life is usually about 5 years, more than this period, the tire will begin to aging. Tire aging is the main performance of the surface hardening, followed by turtle cracks. Aging tires will lose their elasticity, continue to use, then will lead to tread deformation, there is the risk of puncture.
