Nowadays, cars are getting cheaper and cheaper, and there are more and more friends who have cars, and parking is difficult to become a social problem. Some riders in order to park conveniently, often drive the car to the road teeth, it is very easy to knock off the side of the tire, then, the side of the tire knock off a piece can still drive?
Radial tire structure diagram, carcass layer is the cord layer, broken will bulge. The side of the tire is the weakest, the rubber protective layer is thinner, there is no additional layer, and it is easy to hurt the cord line.
The side of the tire is bumped into a small piece, which is divided into the following situations:
- Neither the curtain line nor the air leaked, so you can continue to use it. However, in order to prolong the service life of the tire, it is best to make up the rubber protective layer to reduce corrosion aging and achieve the role of protecting the cord.
Neither leakage of the curtain line, nor air leakage, it is recommended to make up the protective layer to prolong the service life
2. If the side cord layer has leaked out, but the cord line is broken no more than 3, the tire is not leaking, you can continue to use, but the rubber protective layer on the side must be made up.
The cord line is not broken more than 3 times, the tire is not leaking, and the rubber protective layer must be repaired
3. The side of the tire leaks air, but the wound is not large, less than the length * width 30 * 20mm, in the repairable range, direct heat repair is.
The wound is within the repairable range and is directly heat repaired
4. The side of the tire is bulging, which must not be repaired and must be replaced immediately.
The tire bulge is caused by the rupture of the curtain layer on the side, and the rupture of the cord layer cannot be repaired, whether it is cold repair, hot repair, mushroom nails, and laminated strips, it is ineffective. To prevent punctures, they must be replaced immediately.
The side bulge indicates that the cord line is seriously broken and must be replaced immediately
Write at the end:
When the sidewall damage is not serious, it can be repaired, but it has lost the original calibration safety and service life, and there are certain safety hazards. Especially when running long distances and running high speeds, due to long-term high-speed driving, the tire temperature rises, which will lead to an increase in tire pressure, and weak repairs are very prone to danger, and should not continue to be used normally. For safety reasons, it is recommended to use this repaired tire as a spare tire.
suggestion:
In order to avoid the side of the tire being scratched, the following should be done:
1. Pits, holes or other bad road surfaces should be slowed down to prevent severe impact on the tires;
2. It is forbidden to speed or overload;
3, try to avoid sharp turns, sharp brakes and other bad driving habits, especially some riders in order to facilitate parking, often on and off the road teeth, this way of driving on the tire damage is very serious.
