In addition to the important parts used car to look at, we must also pay attention to the used car tires. A friend of the reporter bought a used car. At that time, the owner of the used car dealer said that the tire was brand new, so the friend did not pay any attention to the tire. As a result, it took a few days after the buy-back to find that the tire was refurbished. In response, car professionals said that when buying a used car, it is important to see if there are any problems with their tires.

The first thing to look for is whether the tire has internal injuries, such as hardening or aging. To see if the tire was replaced. It depends on whether or not the tires have been filled with shoddy. There is no quality problem with such tires. It will not be long before the tires are used.

In addition, it depends on whether the tire has been refurbished. The biggest difference between the retreaded tyres and the brand tyres is the wear resistance. The most intuitive way to judge is:

Look, tire tread presents blue light, the color is more natural;

Press and press the tread with your finger, if there is no fingerprint left, then it meets the quality requirements;

Pull, the rubber nail on the tread is not easy to tear, and it can be restored immediately after release;

Plan to use your fingernail to pass over the tread. If no fingerprint is left, the quality requirements will be met.
