The tires of the car are equivalent to the shoes on our feet. A pair of suitable good shoes can make us walk like flies. However, if the shoes go wrong, it may be uncomfortable to walk, or it may even cause a fall or even sprain. The tire of your car is inevitably punctured by sharp objects. Do you know how to deal with a flat tire? Here are some tips:

First aid: The most common way to repair a tire with a gun is to insert a special rubber strip into the puncture part of the tire, which is usually called a gunshot repair by the master of a tire repair shop. The greatest advantage of this method is that it is fast and convenient, only takes a few minutes, and it does not need to pry the tire off the rim. The defect of gun type tire repair is that it is not durable enough, and it is also difficult to deal with large wounds, so it can only be used as a temporary remedy.

Blocking type: adhesive patching is another type of tire patching. The so-called sticking repair is to remove the injured tire from the steel rim, find the wound, and then paste the special tire repair rubber from the inner layer of the tire to complete the leak repair. The advantage of this method is that it can repair large wounds, but the disadvantage is that it is not durable enough. After a period of water immersion and high-speed operation, air leakage will occur again at the repair site.

Finalization: The most thorough tire repair measure is the fire repair. For fire repair, pry off the tire, attach the special raw rubber sheet to the wound, and then bake the wound with a baking machine until the raw rubber sheet is completely fitted with the tire. The advantage of fire patching is that it is very durable, and there is no need to worry about repeated air leakage. However, it also has a disadvantage, that is, the technical requirements during construction are high, because once the baking temperature is not well controlled, it is likely to scorch the tire, and even cause deformation in serious cases. In that way, the damage to the tire will be great.

Professionals point out that the methods of tire repair are diverse, but not omnipotent. If there is a wound larger than 1cm on the tyre wall (i.e. the side of the tyre), or the tyre crown is pierced by steel bars and other objects, causing a big leak, it is generally better to replace the tyre with a new one. Because such tyres are not only difficult to repair, but also the effect after repair is not reassuring. Just let it retire.

As for do it yourself, many automatic tire repair agents on the market have certain effects, but they also have strong limitations. For example, if the tire that has been repaired leaks out of gas, it will be difficult to work. The biggest defect of this tire repair agent is that it is very corrosive. Whether it is steel rim or alloy rim, it will be damaged for a long time. The direct result of this damage is that the seal between the steel rim and the tire is not tight, leading to air leakage.
