【Car owner's family car knowledge】In addition to the important parts of second-hand cars, we should also pay attention to the tires of second-hand cars. A friend of the reporter bought a second-hand car. The owner of the second-hand car dealer said that the tires were brand new, so the friend did not pay attention to the tires. As a result, I drove a few days after I bought it back and found that the tires were retreaded. In this regard, some automotive professionals said that when buying a second-hand car, you must check whether there are problems with the tires.
First of all, it depends on whether the tire has internal damage, such as hardening, aging and so on. Check to see if the tires have been replaced. It also depends on whether the tires have been repaired and shoddy. This kind of tires does not seem to have quality problems. In fact, the tires will die in a short time.
In addition, it is to see if the tires have been retreaded. The biggest difference between retreaded tires and brand tires is in wear resistance, and the most intuitive way to judge is:
Look, the tire tread shows blue light, and the color is more natural; press, press the tread with your fingers, if there are no fingerprints left, it meets the quality requirements; pull, the rubber nails on the tread are not easy to break, and can be released after release. Immediately restore the original shape and scratch the tread with a fingernail. If no fingerprints are left, it meets the quality requirements.
