Excessive wear of car tires can cause harm
Since the tire pressure is reduced by about 30% per year in the natural case, it is necessary to ensure that the tire pressure (including the spare tire) must be carried out regularly. Kumho tires and other tire brands often held free testing services, Zhao, director of the proposed owners to the manufacturers to accept professional, comprehensive tire medical examination. In addition, the air pressure maintenance should also pay attention to: tire cooling measurement of air pressure, a day before driving a visual inspection; high speed before driving the tire pressure is usually increased by 10%, reduce heat, improve safety; understanding of the tire sidewall identification of the maximum pressure value, Under the guidance of professionals approved the normal pressure value, to ensure the best performance of the tire to play. To extend the service life of the tire, must ensure the correct use, careful inspection, careful maintenance, but with the life of the most closely related to the quality of the product itself. Therefore, Mr. Zhao suggested that: in the purchase process to choose the strength of the service and thoughtful big brands, these brands of product classification meticulous, targeted and strong. In order to make the tire wear evenly, the front wheel positioning must be carried out correctly. Poor front wheel positioning is often caused by tread feathery wear, front wheel positioning, including the front beam value, the main pin angle and the main pin angle adjustment. The front beam value is too large will lead to tread outside the feathery wear, too large negative front beam will make the tire bumps on the inner shoulder pinch wear, the front beam value is not correct at the same time will cause diagonal direction of scratches or It is very important to have uniform tread wear on the tread edge.
In general, the normal use of tire life is 4 to 5 years, after 5 years even if the tread wear is also very small and the best replacement, because the tread rubber will be due to the long time and aging, and many small cracks Is the cause of puncture incentives.
