Under normal circumstances, you can run at a high speed after a flat tire, but you can't run at a high speed under special circumstances! The front of a car tire is the strongest and the easiest to puncture. Generally speaking, the probability of puncture at the front end of automobile tires is the highest, and it is normal for tires to roll off the ground.

This defect is also relatively easy to repair. The repair shop can repair it for tens of dollars. Of course, the repaired tires can continue to drive at high speed, and there is basically no need to worry about the so-called puncture problem, especially the hole is relatively large. Mushroom nails should be used to mend tires. After piercing the stud bolt, it will only puncture the tire rubber, resulting in air leakage, and will not cause large-scale damage to the tire skeleton. Therefore, the main effect of nailing is that the tire sealing ring is damaged, which makes it unable to maintain pressure normally, which affects driving and tire performance.

At this time, a grinding wheel or grinding head is used to grind the air leakage inside the tire to expose new glue, and then cold patching glue is applied, which is a low-temperature vulcanizing agent. When the rubber is dry, the cold glue is finally stuck to strengthen the cross-linking between the vulcanizing agent tire rubber and the cold glue. It is a molecular handle, and the combination of the two completes the sealing of the puncture position, and the tire air tightness is restored again, and the tire skeleton is not seriously damaged, so it can be used normally.

If the anti-skid nails on the tires are thin and the air leakage is slow, such tires can be repaired. Under normal circumstances, it can be said that there is no problem in driving at high speed. If the punctured hole is large, it cannot be repaired at high speed by this method. At high speed, the friction increases and the heat generated is also large, so the original wound can be easily opened.

Rollover is very dangerous. It is recommended that the punctured tire be as close as possible to the rear wheel of the vehicle. This situation is relatively safe. Even if there is a tire problem due to an accident, the risk of tire puncture at the rear wheel is different from that at the front wheel, so even if it is not at high speed.

You can also fix a broken tire on the rear wheel in a radial tire. The inner liner is used to provide strength, bear load and maintain the stability of the tire. It is like a pillar in the house, supporting the framework of the whole house. Finally, the main structure that affects tire safety is the layer between tread and tire bottom.

Generally, there are five layers of cords in the crown, including one layer of nylon cord, two layers of steel cord, two layers of polyester cord and five layers of cord. The damage of the crown with a diameter less than 6mm will basically not affect the function of the inner liner and the structure of the tire itself. If the tread is punctured, the most economical way is to repair the tire.

Repairing a tire is very simple. Pull out the tire with a tire knife, drill holes with an angle grinder to increase the grip, and then find a patch to stick it on. In most cases, this is because the main component of the tire is rubber, which has a great extrusion force, and the inside is repaired, and there are almost no cracks in the outside rubber.

Many times, when a flat tire needs to be repaired, it is best to get enough air first, and then drive quickly when it leaks. Cosmetics are also determined by the strong extrusion force of rubber. Tire repair is the most traditional method. The inner wall of the tire is polished, glued, repaired and compacted to restore the inner layer.

This method sacrifices the speed grade of the tire, but does not specify how much it can be reduced. Of course, this is related to the quantity, location and scale of maintenance. A flat tire can be repaired, but only on the tread. Because of the repeated deformation of the crown and sidewall, it is not completely reliable to repair the tire with nails. If this happens at high speed, a tire with slight air leakage is easy to burst. In addition, the tire must be rebalanced after repair.
