1. Advantages and disadvantages of a rubber patch:
The most common way to repair tires is to insert special rubber strips into punctured parts of tires, tire repair shops usually call this cannon tire repair.

Benefits:
The biggest advantage of this method is that it is quick and easy, takes only a few minutes and does not require removing tire from rim.
Weaknesses:
It's not strong enough, and it's easy to cause slow air leakage. In addition, since awl or gun used in repairing tire may cause secondary damage to tire, steel cord is easily damaged. exposed and rust! lead to risk of tire burst. In addition, large wounds are difficult to manage, so it is usually used only as a temporary remedy.
2. Advantages and disadvantages of cold tire repair:
Cold sealing is a common way to repair tire leaks. When you go to a tire specialty shop for tire repair, it is common for shop technician to take lead in implementing this method. First of all, find wound on flat tire, then remove tire from rim, polish wound on inside of tire, apply special glue, stick special tire repair rubber, and finally use tools to roll until it is firmly glued , complete tire repair.
This method is similar to bicycle tire repair method, but requires a special tire changer and tire repair film to complete. Although this method can repair a large amount of damaged surface on tire, it is not durable. After a period of immersion in water or driving at high speed, air leakage may occur again in repaired area.
Benefits:
Relatively strong, but not once and for all. In addition, after repair, tires usually undergo dynamic balancing, which is more conducive to tire operation. As for repair price, it will vary depending on quality of tire repair rubber you choose and range from 20 yuan to tens of yuan.
Weaknesses:
It is not strong enough, and after a period of immersion in water or driving at high speed, patch may again leak air.
Third, advantages and disadvantages of repairing tires with a rubber nail (mushroom nail):
Putting a mushroom nail involves using a mushroom-shaped rubber patch to locate hole inside tire, pushing root of fungus out, and then cutting off excess that is protruding from outside. The inner part is glued with special glue. The leak repair method is same as cold repair, difference is that final process is to pull rubber nails out of hole to block hole, avoiding damage to steel wire and layer due to water immersion through hole. hole, and price is relatively expensive, generally used to compare wounds Excellent location.
The root part of mushroom can have an external tonic effect, while inside of mushroom is equivalent to an internal tonic effect. According to reports, method of repairing mushroom nails is better, but repair process takes a long time, usually about half an hour. Its price is also slightly higher than price of ordinary tire repair, which is 20 to 30 yuan, usually 100 yuan or even higher.
Fourthly, advantages and disadvantages of fire tire repair:
The most thorough tire repair is often referred to as a fire repair. During fire repairs, it is also necessary to pry off tire, then apply a special raw film to wound, and then bake wound in a baking machine until raw film and tire are completely fused.
The fire patching method is similar to cold patching method. It also attaches a special film to gap, but there is an additional step that requires an oven to bake gap until film melts and sticks to gap. . . .
Therefore, advantage of a fire-fighting repair is that repaired site is very durable, and basically there will be no re-leakage of air. But wrong heat supplement can also harm fetus. Thermal correction has strict requirements for heating temperature and time, especially passenger car tires are thinner than big truck tires, improper heating and excessive temperature can damage the tires.
Benefits:
It is very durable and there is little to worry about re-leaking air.
Weaknesses:
The design requirements are relatively high because if heat is poorly controlled during firing, tires are likely to burn and, in severe cases, warp. So tire damage will be great.
What is best way to repair a car tire?
The outer rubber strip is comfortable to use, but its durability is average. When tire is nailed and nail hole is small, it is a good emergency choice to use an external rubber patch to repair tire.
Although hot patch only repairs inner skin, since hot patch film and tire inner skin are fused together, sealing effect is better and air leakage is difficult. But larger hole from nail, less durable hot patch tire will be. When tire is nailed and nail hole is small, hot tire repair has best effect, and durability is also good.
Despite fact that cold repair is highly timely, it places higher demands on tire fitters. In addition, it is a waste of time to disassemble and reassemble tire for repair when test is completed with a cold patch repair.
If not necessary, use other tire repair methods.
