18 years with the old E for the new E300L luxury, has been stable use, follow the guidance of the old strict, pay more attention to the use of delicate explosion-proof tires, from tire pressure 2.0 to use habits, are relatively mild. But thousands of attention, but also can not stand the large-scale development of the northwest, roads are dug everywhere, finally, at dusk, the speed of more than 60 mph suddenly, the right front wheel jumped into a shallow hole, in fact, the speed is not fast, but it is obvious that the tires are hard to resist. Due to the traffic flow, I didn’t stop and drove all the way home. I got out of the car to check. There was a black mark rubbed off from the tire on the hub. I was glad to check the tire carefully with a flashlight.

About two weeks later, when I had just parked my car at work, I suddenly reported to the police that the tire had lost pressure and looked confused. I drove the car slowly to a nearby BBA repair factory. After careful inspection, the workers did not find that the tire was stuck by a nail and so on. I immediately filled the air and let me observe carefully. Well, when the alarm was lifted, I remembered that the old E had a similar situation. After running over the highway, the tire would occasionally lose pressure. I didn’t care too much.
Next, Xi’an was blocked. In the first month before the Spring Festival, the car stopped motionless and went to nucleic acid every day until the alarm was lifted and went downstairs to drive. This was good. The tire pressure alarm came again. Fortunately, I bought an air pump. Doodle filled the gas to 2.2 and went out to work in a hurry. Two weeks later, the tire called the police, and I drove the car to another repair shop again. It’s still the same. I didn’t find it out. I made up the breath and gave way to observation. All right, the next step is to keep replenishing the air by yourself, raising the pressure to 2.5, which will drop to 1.7 in two weeks and cause the police to call the police. Infinite cycle, dizzy to death. The security guard downstairs is used to it. As long as I squat by the car, the security guard will come up and ask, “is he out of breath again?”
Epidemic situation, business, work, air replenishment, air leakage, alarm, air supply, alarm, repeatedly, make do for more than half a year, and finally got free a few days ago. I thought of the Chaoyang tire recommended by Lao Yan. Think about it, or change the tire. Pick up the map and search for a Chaoyang tire monopoly of some scale. I called, and they asked about the situation and said that they would drive the car over and they came to check. Talking about high probability can find out the problem. With the idea that I couldn’t change the tire, I drove the car straight past. Chaoyang Tire passed through the Nine Route Store. The boss, surnamed Zhang, looked very capable and smart. He personally observed the tire and looked for the problem. Finally.

I don’t know if the video can be put up, so I can only take a screenshot for everyone to see, very slow, one bubble after another, very slow.

Finally found the reason, relieved, or very happy, then, take off the tire, the tire did not find abnormal, check the hub, seams and some tiny protuberances, like goose bumps, Chaoyang tire gave the reason, said that when washing the car, the tire wax corroded the tire seams, coupled with external pressure, resulting in air leakage at the seams.
Next, take the grinding wheel to polish the tire surface and hub at the tire seam until smooth, install the tire, and dynamically balance.

So far, 30 ocean has solved all the problems. The level of Chaoyang tire monopoly is really good. I like it here.
To sum up, the use of tires is very important. in addition to the tire pressure emphasized in the forum, controlling the speed over the speed deceleration zone and crossing the pit, it is best not to brush tire wax in the car wash shop, otherwise the quality is unpredictable and the loss outweighs the gain. I haven’t written a post for a long time. I want to share my experience and offer it to you. I wish all of you in the Mercedes-Benz Forum are well, Lao Yan and auspicious.With so many words in the code, I don’t know if the main shot of the version is not set.?
