Many car owners have asked reporters similar questions.
To this end, the editor conducted some research and found that although there are various tire repair methods such as cold patching, hot patching, and rubber strips on the market, these can be roughly divided into two categories: external patching methods and internal patching methods. The internal repair method is further subdivided into cold repair method (internal repair or pasted repair), hot repair method (commonly known as fire repair), mushroom nail repair method and automatic tire repair liquid method. Each method has its own advantages and disadvantages, and car owners can choose according to their needs.
Glue strip: simple emergency can
The most common method of tire repair is to insert a special rubber strip into the punctured part of the tire. The masters of the tire repair shop usually call it gun-type tire repair. The biggest advantage of this method is that it is quick and easy, taking only a few minutes, and there is no need to pry the tire off the rim. The disadvantage is that it is not durable and difficult to cope with larger wounds. It can usually only be used as a temporary remedy. If you want to continue to use the tire, it must be repaired internally.
Cold patching: convenient but not durable
During cold repair, you need to remove the tire from the rim, find the breach and clean up the foreign objects around the breach, and then apply a special tire patching film from the inside of the tire to complete the leak repair. This method is similar to the bicycle tire repair method, but it requires a special tire stripper and tire repair film to complete. Although this method can repair larger damaged areas on the tire, it is not durable. After a period of water immersion or high-speed driving, air leakage may occur again in the repaired area.
Hot supplements: also good, but you need to find a reliable merchant
The hot repair method is similar to the cold repair method. A special film is attached to the break, but there is an extra step. You need to use a baking machine to bake the break until the film melts and adheres to the break. Therefore, the advantage of hot patching is that the repaired area is very durable and will basically not leak air again. However, improper heat patching may also damage the tire. Hot patching has strict requirements on heating temperature and time. Especially the tires of private cars are thinner than those of large trucks. Improper heating and excessive temperature may damage the tires.
Mushroom nails: good results but high price
The mushroom patching method, as the name suggests, uses a mushroom-shaped rubber patch to find the hole inside the tire, pass the mushroom root out, and then cut off the excess part exposed. The inner part is glued with special glue. The root part of the mushroom can have an external tonic effect, while the inner part of the mushroom has an internal tonic effect. According to reports, the repair method of mushroom nails is more effective, but the repair process also takes a long time, usually about half an hour. The price is also higher than the ordinary tire repair price of 20 to 30 yuan, usually 100 yuan or more.
Automatic tire repair fluid: emergency only
At present, most models are equipped with conventional spare tires, but a few models have canceled the spare tire assembly due to space constraints (except for some models equipped with run-flat tires), and use tire repair fluid instead. This tire repair fluid is a synthetic polymer compound in the form of a white foamy liquid, which is stored in a compressed air tank. When used, it is injected into the tire through the valve, and the pressure of the compressed air tank is used to inject the liquid into the tire while inflating the tire. Afterwards, by driving, the tire repair fluid in the tire evenly covers the inside of the tire under the action of centrifugal force, forming a sealing film on the inside surface of the tire to repair the tire. This method is an emergency tire repair method when no obvious breach can be found. However, the tire repair effect is limited and the persistence time is limited. Therefore, tire sealant is only an emergency product, used when there is no spare tire, no repair shop, and you have to move on.
Can any tire be repaired?
Can any tire puncture be repaired? Of course not. Whether it can be repaired depends on where the tire damage is and the severity of the injury.
If the tire is punctured with holes in the sidewall or tread, or if the tire crown is punctured by steel bars or other objects, causing a large hole, you should still replace the tire with a new one. Because a tire that has suffered such heavy damage is not only difficult to repair, but the effect after repair is not reassuring. Tire repair is not a panacea, especially for car owners who use emergency tire repair methods such as automatic tire repair fluid and gunshot method. It is recommended to find the nearest repair point as soon as possible to repair or replace the tire.
What should you pay attention to after tire repair?
After the tire repair is completed, be sure to check the dynamic balance of the tire, because repairing the tire will destroy the dynamic balance of the tire. If the tire is not checked, it will cause vehicle vibration and high fuel consumption. Professional maintenance technicians said that as long as it has passed the tire dynamic balance test, it can be placed on the front and rear wheels. At the same time, the maintenance master also suggested that car owners can always keep a small electric air pump in the car to inflate the tires emergencyly when encountering similar situations. The price of an electric small air pump is about one or two hundred yuan. After inflating, the vehicle can usually drive for half an hour without any problems, so that you can find a nearby repair shop or tire repair place.
