Measures to prevent tire wear

the reasons for premature tire wear are: the wheel hub bearing is loose, causing the wheel to swing; The vertical shaft pin sleeve is loose, resulting in the change of camber; The ball head of the steering rod is loose or the steering knuckle arm is loose, causing the toe in value to change; The deformation of the tie rod directly affects the toe in value and camber angle; The wheel hub is deformed, causing the wheel to swing back and forth during driving; Improper toe in value or camber adjustment

1. Forms of tire wear

there are five forms of tire wear: one is the wear on both sides of the tire, mainly due to insufficient tire pressure, and the large contact area between both sides of the tire and the ground accelerates the wear. Moreover, long-term driving of the tire can also accelerate the wear on both sides of the tire. Second, the tire is worn on one side, mainly due to the inaccurate positioning of the tire. When the camber angle of the tire is too large, the outer edge of the tire will wear out prematurely; On the contrary, when the camber angle of the tire is too small, the inner edge of the tire will wear out prematurely. Third, the middle of the tire is worn, mainly because the tire is inflated too much, resulting in premature wear in the middle of the tire. Fourth, the tires have serrated wear, the tire positioning is inaccurate or loose, and the tires constantly swing during driving, resulting in serrated wear of the tires. The suspension system fails, causing the tire to slide in rolling, and the tire wear is serrated. Fifth, the tire appears bald wear, mainly due to the poor balance of the tire. When the tire rotates at high speed, due to the imbalance of the tire, the stress on the protruding part of the tire is large, resulting in bald wear

2. Measures to prevent tire wear

(1) tire pressure should meet the standard. High or low tire pressure will shorten the service life of the tire, so check whether the tire leaks after inflation, and regularly check the tire pressure to ensure that it meets the standard requirements. When checking the tire pressure, use the barometer instead of judging with naked eyes. It is necessary to ensure that the tire has a certain elasticity, and its deformation does not exceed the specified range with the specified load, so as to ensure that the vehicle has good stability and comfort during driving

(2) regularly check the front wheel alignment and tire dynamic balance. Excessive camber of the front wheel will cause eccentric wear of the tire, and improper toe in will cause wear on the inner and outer sides of the tire

(3) correctly select and install tires, and use corresponding inner tubes according to tire specifications. The tires assembled shall ensure the unity of brand and structure; When changing a new tire, the whole machine or the coaxial line should be changed at the same time; Tyres with directional patterns should be installed in the moving direction according to the specified flow. Any link from testing to utilization must be completed with high quality in order to maximize the performance of the material

(4) regularly rotate the tires. After driving for a period of time, you should change the position in time according to the regulations

(5) pay attention to the control of tire temperature. When the temperature of the tire is very high, the method of deflating and depressurizing cannot be adopted, let alone splashing water on the tire to cool down. Stop the machine in a cool place and rest until the tire temperature naturally decreases

(6) develop the habit of stopping safely. To choose a flat and dry ground, the most important thing is to park on a clean and oil-free ground. When it is shut down for a long time, the frame should be supported with wood blocks to reduce the load on the tires; Jack up the wheel when there is no air pressure in the tire

(technical specification for welding of building steel structures JGJ 81 ⑵ 0027) tyres should be avoided from being stored near sunlight, oils, acids, combustibles and chemical corrosives. Tyres should be stored in cool, dry and dark rooms. The tires should be placed vertically, and it is strictly forbidden to put them horizontally, stack them or hang them across the center

(8) avoid sharp stones, glass, metal and other objects from puncturing the tire when the machine is running. When changing, slow down and drive in the middle as much as possible

(9) during construction in severe cold areas in winter, the brittleness of rubber tires increases and the elasticity decreases. When the vehicle is parked overnight or for a long time, it should start smoothly and drive at a low speed, and then drive normally after the tire temperature rises
