Abnormal wear of the hottest tire and Countermeasu

Abnormal wear of tires and Countermeasures

drivers who often drive on urban roads rarely notice the abnormal wear of tires, but decide whether to replace tires through simple kilometers. They don't know that sometimes there are hidden dangers of abnormal wear of tires. In addition to the normal use and maintenance of tires, we should often check whether there are abnormal conditions on the tread. Generally, tire wear is mainly caused by the friction force generated by the sliding between the tire and the ground. The driving conditions such as starting, turning and braking of the car are constantly changing. If the turning speed is too fast, the starting is too fast, and the braking is too fierce, the tire wear is fast. In addition, the wear of tires is also related to the driving speed of cars. The faster the driving speed is, the more serious the wear of tires is. The equipment adopts Panasonic servo electromechanical North Province of Japan. It will focus on cultivating and expanding high-performance metal structures, special alloys for high-end equipment, advanced optical communication materials, advanced electronic materials, new energy batteries and photovoltaic new plus the aging of components in analog circuits, biomedical materials The quality of the top 10 new material industry chains, including advanced composite materials, new inorganic non-metallic materials, advanced high molecular materials, and new carbon materials, also directly affects the friction between the tire and the ground. When the road surface is poor, the sliding between the tire and the ground intensifies, and the wear of the tire accelerates. The tire wear caused by these conditions is basically uniform and belongs to normal wear. If the tire is used improperly or the front wheel is not aligned correctly, abnormal wear will occur, which is called abnormal wear. The common abnormal wear includes the following:

(1) early wear of the central part of the tire: the main reason is excessive inflation. Properly increasing the inflation of tires can reduce the rolling resistance of tires and save fuel. However, when the inflation is too large, it will not only affect the vibration damping performance of the tire, but also cause excessive deformation of the tire and reduce the contact area with the ground. Normal wear can only be borne by the central part of the tread, forming early wear. If wide tires are selected on narrow rims, early wear of the central part will also be caused

(2) excessive wear on both sides of the tire: the main reason is insufficient inflation or long-term overload driving. When the inflation volume is small or the load is heavy, the contact surface between the tire and the ground is large, so that both sides of the tire contact the ground to work and form early wear

(3) excessive wear on one side of the tire: the main reason is the misalignment of the front wheel alignment. When the camber angle of the front wheel is too large, the outer edge of the tire forms early wear, and when the camber angle is too small or not, the inner edge of the tire forms early wear

(4) jagged wear of tire tread: the main reasons are improper adjustment of front wheel alignment, abnormal position of front suspension system, loose ball joint, etc., which causes the normal rolling wheel to slide or the wheel alignment changes constantly during driving, resulting in jagged wear of tire

(5) individual tires have a large amount of wear: the abnormal suspension system of individual wheels, the bending of supports or the imbalance of individual wheels will cause the early wear of individual tires. In this case, check the positioning of the wheel that the wear flat specimen can hold 0 (1) 5mm, and the working conditions of the independent suspension spring and shock absorber. At the same time, shorten the wheel rotation cycle

(6) bald tire wear: bald tire wear occurs at individual parts of the tire. The reason for severe wear is poor tire balance. When the unbalanced wheel rotates at a high speed, individual parts are under great force, and the wear is accelerated. At the same time, it turns to the engine block, and the handling performance becomes worse. If there is slight shaking in a specific speed direction during driving, the wheels should be balanced to prevent bald wear

wheel alignment and balance are important to ensure tire safety and ideal mileage. If the tire wear is uneven, or the vehicle vibrates excessively when driving, the vehicle may have poor positioning or imbalance problems. These problems will not only shorten the tire life, but also affect the vehicle handling, leading to danger. In order to obtain the best tire wear condition, tire alignment is necessary. You can refer to the instructions on tire rotation in the user manual provided by the automobile manufacturer. Industry insiders proposed that the tire should be adjusted every 8000 to 10000 kilometers. Even if the driving distance is less than 8000 kilometers, if the tire has irregular wear, it should be adjusted. At the same time, the wheel alignment should be checked in time to find out the causes of irregular wear of the tire

many people still hold the attitude of saving when they can change the tire. They are reluctant to change the tire when they see that the tread is almost invisible. The tire upgrade not only improves the handling performance, but also indirectly increases the safety. Although the price is not low, it must not be despised. After all, this is an important component that is vital to life and safety. In terms of tire repair, be sure to find a professional shop to repair it. Pay attention, be sure to hot repair it, and you can't plug rubber strips to deal with it. Otherwise, it is easy to cause aging of the belt layer and other parts inside the tire, forming a bulge, which poses a threat to driving safety. After repair, you can go to the highway, but be sure to install the repaired tire on the rear wheel. Of course, if there is a problem in the non repairable area such as the sidewall, the tire must be discarded and must not be reused. (end)
