(1) Safe storage

All tires should be stored indoors in a cool, dry, and dark environment, avoiding exposure to sunlight, oil, acids, and hydrocarbons that can corrode the tires. Due to pressurization, liquid may enter the tire body layer through the internal airtight layer of the tire, which can cause sudden damage to the tire.

(2) Tire maintenance

Timely replacement of tires, selection of appropriate patterns, daily maintenance, regular inspection of tire pressure, timely repair of damaged tires, and frequent excavation and cleaning of stones, foreign objects, etc. in the tire tread are all important factors in prolonging tire life. After a period of use, tires are affected by factors such as road curvature, brake braking, and different tire assembly positions, which can cause significant differences in tire wear. Therefore, it is necessary to timely replace and assemble each tire, so that each tire can rotate once in each position, and the load borne by each tire can be roughly the same, in order to solve the problem of tire bias wear and prolong its service life. There are two commonly used methods for tire rotation: "cross rotation" and "cyclic rotation". When mixing new and old tires, if the new tire is good, the new or better tire should be fixed on the front wheel, and if the old or refurbished tire is fixed on the rear wheel, methods such as shifting left and right, shifting inside and outside, etc. should be adopted. When changing the original rolling direction after swapping, the tire should be reversed (i.e. changing the installation position and rolling direction). This is a measure to reduce or even eliminate tire bias, chamfering, and excessive fatigue on the shoulder of the tire. It is also a way to extend the service life of the tire and improve the refurbishment rate.

(3) Ensure standard air pressure

Master the inflation standards of tires and ensure that the tire pressure is within the specified value. Excessive or insufficient tire pressure will increase wear and reduce driving range. When the tire pressure is below the standard value, the wear of the tire shoulder increases sharply; When the tire pressure is higher than the standard value, due to the decrease in tire contact area and the increase in unit pressure, the wear in the middle of the tire tread increases, while also increasing the tire rigidity, which increases the dynamic load on the wheels and easily leads to tire burst. The impact is more severe when driving on uneven roads or at high speeds.

(4) Control tire temperature

When driving a car, the temperature inside the tire increases due to deformation and friction. When it reaches above 100 ℃, the strength of the tire body is greatly reduced, which is prone to damage such as delamination and explosion. Tire temperature is difficult to measure and is usually judged based on the degree of tire pressure increase. The higher the tire pressure, the higher the tire temperature. When the ambient temperature is above 30 ℃, the degree of tire pressure increase should not exceed 20% of the inflation standard. Due to poor heat dissipation conditions, the tire temperature can easily exceed 100 ℃. When driving in high temperatures in summer, if the tire temperature is too high, you should park in a cool place to naturally cool down. It is strictly prohibited to use methods such as splashing cold water or deflation to cool down and reduce pressure. Because splashing cold water will cause the tire to suddenly cool down, causing uneven shrinkage in various parts, making it prone to cracking and affecting its service life. When the weather is hot, if there is a section of road that needs to be crossed by water on the way, you should also stop and cool down first to avoid adverse effects on the tires. If the tire is deflated during the journey, although the tire pressure decreases, the tire temperature does not decrease, but it disrupts the original balance condition. When driving again, the deformation increases due to the decrease in air pressure, which will continue to increase the tire temperature on the original basis until the heat generation and heat dissipation of the tire are balanced again. At this time, the tire temperature will increase significantly, causing serious damage to the tire.

(5) The impact of driving habits on tires

① Start smoothly. Due to the sudden rotation of the wheels from a stationary state, there will be severe friction between the tires and the road surface, which will accelerate the wear of the tire crown Drive at medium speed. According to the data, when the speed changes from medium to high, the tire mileage will decrease by 15%. In addition, the higher the vehicle speed, the greater the frequency of wave vibration. When the vehicle speed reaches a certain critical speed, the wave deformation on the surface of the tire crown will significantly increase, forming a stationary waveform. This is the standing wave phenomenon of tires. When a standing wave phenomenon occurs, the tire becomes out of round, the tire temperature rises sharply, and the ply and tread will peel off and scatter. Small cases can cause tire damage, while large cases may cause major traffic accidents Try to avoid emergency braking as much as possible. During emergency braking, the wheels change from rolling to dragging, causing friction between the tires and the road surface, resulting in severe wear and tear due to overheating. If emergency braking is frequently used at high speeds, it will generate a large amount of heat, causing tire aging and causing malignant damage to the tire.

(6) Routine inspection before driving

Before driving, check the tires for bulges, cracks, cuts, punctures, lack of air, and abnormal wear. If any are found, they must be repaired immediately. Check if there are any foreign objects, such as debris, metal sheets, glass, or stones stuck in the tire groove on the tire surface. If found, use a screwdriver to remove them. Check the tightness of the tire fixing nuts and tighten them promptly if any looseness is found. If the tire pressure is found to be 20% lower than the standard, it is necessary to go to the nearest tire shop as soon as possible to remove the tire and have it inspected by professional personnel. Pay attention to whether the wheel rims of the vehicle are deformed, cracked or damaged, in order to ensure driving safety.
