1, if the tire crack is more, and the distribution is uniform, this phenomenon is caused by the aging of the tire, and the comparison of tire years, kilometers, general tire replacement cycles for about 6 years, km The number is around 80000km. It is recommended to replace the tire in this state because the aging tire pattern is relatively shallow, which will affect the braking distance, thus affecting driving safety.
2, the tire crack is relatively small, the number of vehicles is less kilometers, if cracks are damage caused by foreign matter on the road, need to judge the position of the crack and the depth of crack, generally cracks in the side position of the fetal side Replace the tire because the fetal side is relatively thin, there is a risk of leakage, and it is not easy to repair, and there is a risk of puncture when driving at high temperature. If the crack is on the front of the tire and the crack is not deep, it can continue to be used without replacement. If the crack reaches the degree of the dew, it is recommended to replace the tire in time to avoid loss of loss.
3, the tire front tires can be considered for replacement tires when the predecessor depth of the tire is less than 2 mm. When the tire pattern is too low, the water-saving performance of the tire will deteriorate, affect driving safety. It is recommended to replace it in a timely manner.
