How often do they need to be replaced or when they need to be replaced?
1, to improve the understanding of tire safety, usually to check the tires, especially on high speed, we must be fully detailed examination, in addition to outside pressure, but also to observe whether there is a side of the tire, tread wear, found hidden should be excluded.2, regular correction wheel balance, wheel imbalance is excessive, high speed will produce high frequency oscillation, causing tire partial wear, is not conducive to driving safety. After the tire repair, should go into the action balance test adjustment, the tire side dynamic balancing test value should be less than or equal to 40 grams.3, carry out regular tires, in order to maintain the same car tire wear uniform, vehicle traveling 5000 kilometers each should make a tire rotation, every 5000 ~ 10000 km for a four round of positioning, in order to avoid the tire abnormal excessive wear, are not allowed to install tires of different types or larger differences in the same old a shaft.
Focus on the side walls of the car tires: as the tire rubber aging, the tire side wall will appear deep lines. However, as long as the sidewall of the tire is not impacted and the cord is not broken, it can continue to be used. The triangle mark on the side wall of the tire can help the owner find a protuberance in the groove of the crown, and can determine the actual wear limit of the tire. The value should be greater than 1.6 millimeters.
From the line of tyre usage, there will be four digits on the side wall of the tire indicating the date of manufacture of the tire, the first two representing weeks, and the last two representing the year. The use of tires generally do not exceed 3 years, mileage is not more than 60 thousand kilometers. Although slightly longer than the length of life and mileage is no harm to the overall situation, but the winter low temperature and summer rain will make the tire of wetland grip and dry ground handling is relatively poor.
