In European countries, when a car travels an average of 75,000 kilometers, it will encounter a tyre puncture.
In Asia, because the road conditions are worse than in Europe, a tire puncture occurs on average every 3,000 kilometers. Therefore, tire repairs are more or less experienced for drivers.
Many drivers don’t understand, can they still go on high speed after the tires are patched up?
This question cannot be generalized. Whether you can go to high speed after repairing a tire depends not only on the damaged part, degree of damage and repair method of the tire, but also on the number of times the tire has been repaired.
Tire repair methods are usually divided into two types: external repair and internal repair.
External filling rubber strip
When the tire encounters a puncture, the hole is properly enlarged with an awl or other foreign objects, and then a rubber strip coated with glue is inserted into the hole.
As the tire runs and the temperature increases, the rubber strip will soften and prevent the air inside the tire from leaking.
Advantages: The repair is simple and convenient, and very cheap. When the tire damage is small, it can be used as an emergency option.
Disadvantages: The durability is average, it will foam after a period of use, causing the holes to leak again.
This method is very common and is the same as repairing bicycle tires. First remove the damaged tire, polish the punctured part on the inner side of the tire, then apply glue, dry it, and paste the tire repair film.
Finally, use a tool to roll the tire repair film until it is completely bonded and firmly bonded.
Advantages: simple operation, better effect and lower cost.
Disadvantages: High requirements for repair technology, such as improper operation and weak sealing, which may cause air leakage again.
Internal subsidy film hot patch
The operation process of this method is similar to the cold patching method of internal subsidies, but a process is added at the end, that is, high temperature heating treatment with a vulcanizer.
After adding this procedure, the tyre repair film and the tyre are fused together, so it is stronger.
For a long time, this method was considered the best way to repair tires.
Advantages: good sealing.
Disadvantages: family car tires have thin walls, and high temperature heating will accelerate the aging of the tires and lose their elasticity and impact resistance.
In addition, it is easy to cause the inner liner of the tire to melt, causing slow air leakage.
The crown of the mushroom nail can play the same role as the cold patch film, sealing the inner liner of the tire. The nail-shaped part can pass through the damaged hole of the tire to repair the carcass rubber.
Advantages: Taking into account the advantages of the external filling rubber strip and the internal subsidy sheet, the inside and outside of the tire are protected.
Disadvantages: It takes a long time to repair a tire and the price is not cheap.
Internal supplement self-repair
In this way, the tire sealant is injected into the tire. When the tire is running, the semi-dry sealant will be evenly distributed in all parts of the tire.
When the tire puncture leaks, the sealant will quickly reach the leak under air pressure.
The natural rubber emulsion, polymer materials and rubber particles in the sealant will rub against the wall of the damaged hole at high speed under high air pressure, and solidify rapidly during the rubbing process.
Advantages: safe and trouble-free, can prevent air leakage caused by puncture or other in advance, and can repair it instantly when air leakage occurs.
Disadvantages: The protection of the sidewall of the tire is relatively weak and the cost is high.
Comprehensive comparison of the advantages and disadvantages of various tire repair methods, only tire sealant is used to prevent tire repair in advance, and repair it instantly at the moment of assassination.
In the other several ways, the tire is repaired after being assassinated.
In this case, if driving at low speed is fine, you can change tires or call a trailer.
When driving at high speed, you may not even have the opportunity to repair the tire, and the tire will blow out directly and cause the car to die.
In short, it is not suitable for high-speed running after external supplementation, and the safety risks are great. There are several ways of internal compensation, and there is no problem on high speed.
However, if a tire has two or more patches, no matter whether the internal patch is cold patch or hot patch, high speed is not recommended.
However, if the tire sealant is used for self-repair, there will be no effect.
After repairing in this way, the tires are the same as normal. Not only is there no need to repair a tyre, but there is no need to change it.
