After a certain period of time, tires are inevitably subject to wear. Then how long do we choose to replace the tires or how many kilometers is appropriate? Recommendation: The service life of automobile tires is four years or 80,000 kilometers, whichever comes first. This means that if there is no problem with the tire (for example, there are too many tires, sideways, etc.), if the tire service time reaches four years, even if the mileage does not reach 80,000 kilometers, it will be replaced. Similarly, if it does not reach four years, but the mileage reaches 80,000 kilometers, it is also recommended to replace it. Pay attention to the "signal" that tires need to be replaced Although the tires will not actively say to the owner, "I can't support it," but the owner can rely on their own observation and touch to determine whether the tires need to be replaced. 1, tire wear identification There will be wear marks in the groove of each tire tread, and the wear mark thickness of general household cars is 1.6mm. If your tire tread and wear marks are high, it means the tire change. Some owners may say that my tyres have not been damaged and the pattern has been flattened and then used. This kind of tire is very dangerous. The grooves in the tread pattern are mainly for the purpose of removing water on wet surfaces and enhancing the grip. However, the grooves are worn out. The vehicle can easily cause slippage and runaway on slippery road surfaces. 2, the tire appears broken bulging When driving daily, the tires will inevitably be scraped or pinched, for example, when they are parked, they will get to the curb. This can easily lead to damaged bulges or cracks in the tire sidewall. The tire bulging is because the cord inside the sidewall is broken. In this case, it is better to replace the damaged tire in time, otherwise it is easy to have a puncture. 3, tire aging Rubber products have a useful life, such as the door seals, a long time will be aging, there will be strict sealing, cracking and other phenomena. The same is true for tires. Generally, the service life of tires is 3-5 years. It takes a long time even if you drive normally and you are careful about surface hardening and cracking. This kind of tire is to complete its mission. It should be changed. If you continue to use it, there will be a danger of puncture. Expert advice When the car tire wears to the limit, it must be stopped, that is, when the depth of the tire tread pattern is less than 1.6 mm. Tires whose tires are aging or deformed, even if they are damaged, must be immediately discontinued. Therefore, if your car tire has the above conditions, then it is enough to qualify for the tire replacement. We hope that you can immediately replace tires with worn or severe wear to ensure the safety of yourself and others. Tire usually pay more attention to maintenance 1. Maintain sufficient air pressure. "Auto manufacturers will sacrifice tires for the purpose of damping and comfort of the vehicle, reducing the tire pressure." 2.1--2.3KPa>, and the normal air pressure of the tire should be 2.6--3.0kpa. Especially when running high speed and summer, you must not reduce the air pressure, because if the tire is lowering the air pressure during travel, the tire warms up quickly, making the tire change. Soft, rubber and cords, the steel wire flexing constantly, generate a standing wave effect, and a puncture occurs. 3. Pay more attention to the debris inside the tire pattern, such as: small stones, iron filings, glass. . . . . . To clean up in time, because these things wear deep into the rubber as the pattern of the tire, causing the tire to leak and wire, the cord breaks and deformed. 4. Avoid oils. Because oils are chemically-containing, they can cause corrosion to rubber and increase tire aging. 5. Regularly detect four-wheel alignment. Every time the vehicle is driven for 10,000 kilometers or about 3 months, when the chassis parts are replaced, the direction of travel is shaken, and the deviation is detected and debugged. Prevent tires from irregular and abnormal wear. 6. Timely transposition. Every time the tire is driven from 1.5 to 20,000 KM, it must be transposed in time to make the tire wear properly in all directions. 7. Regularly check the tire dynamic balance. In the replacement of tires, tire repair, change the position to test and adjust the balance. Avoid the steering wheel trembling and tire irregular and abnormal wear. Finally: The tires are the feet of the vehicle and are essential for safe driving. The owners should spend more time learning the method of self-testing tires. Usually checking and checking tires will not take much time, but it will allow us to grasp the health status of tires and respond to them in a timely manner. high pressure common-rail fuel filter-HPCR,Diesel fuel filter,Petrol fuel filter,spin on ZHEJIANG UNIVERSE FILTER CO.,LTD. , https://www.unifil.com
