How to repair the side of automobile tire after it is scratched? Is there any saving? (for example)

Car tire side scratches, it is recommended not to repair. Although it depends on the degree of scratch, the side of the tire is scratched, which greatly affects safety. The side of the tire is the thinnest and weakest part. Once there is a scar, the safety performance will be greatly reduced. Even if it works, it is easy to have a flat tire on the road. Therefore, in this case, it is recommended not to repair the tire, but to change it directly, which seems unlucky.

Instead, it's at the bottom of the tire. Although it may seem badly pierced, this place can be repaired in most cases, as long as you don't have a big hole or a badly damaged tire. So under what circumstances should it not be repaired?

1, the tire was punctured, and the diameter of the punctured hole was greater than 6 mm, which could not be repaired. This hole is too big, even if it can't be installed, it's not safe to bear the tire pressure.

2. The side wall cannot be repaired. The side is the thinnest part of the tire. If the side is punctured or punctured, the strength can no longer meet the safety performance requirements of the tire.

3. Damaged or deformed tire bead, deformed tire surface, tire rubber corroded by chemicals, and tire crushed and damaged in the absence of air are irreparable, because the tires are damaged in these cases, which is not a simple repair problem.

4. Other abnormal conditions cannot be repaired. For example, if you can see the traces of air leakage from the tire (such as tire rolling marks, air bubble, etc.). ), it is not worth repairing, because the tire structure may have been damaged and can no longer be used.

In addition, the tire pressure should be closely observed for a period of time after tire repair, because although tire repair has been carried out, the tire pressure may damage the repaired place during use, resulting in air leakage. At this time, it is necessary to repair it in time, otherwise the tire will be deformed when driving under insufficient air pressure, and the tire needs to be changed directly.
