Dear drivers, have you ever been asked, "Do you need to do balancing?" after repairing the tire?"What about this problem?Faced with this problem, many people may wonder, shouldn't you do dynamic balancing after tire repair?Why don't repair shops take the initiative to do it?Today we are going to unravel this mystery. 
First, let's understand what balancing is.
Dynamic balancing refers to a technology that makes the wheel reach a state of balance when rotating at high speed by adjusting the mass of each part of the wheel. It's like a sense of balance in our body, and if we lose our balance, we can stagger, or even fall. The same is true for wheels, if the dynamic balance is not good, the vehicle will produce a sense of shaking and drifting, which will affect driving safety.
The necessity of doing dynamic balancing
The necessity of dynamic balancing is to prevent the unbalanced rotation of tires, and the vehicle will calibrate the dynamic balance of each tire when it leaves the factory, and paste the balance weight to ensure the smooth operation of the high-speed rotating tires. However, with the use of the vehicle, the balance state of the tire may change, such as bad driving Xi, tire disassembly or replacement, etc., may lead to changes in the dynamic balance state of the tire, wheel swing, high-speed steering wheel shake and other conditions, bringing hidden dangers to driving safety. Therefore, it is necessary to do wheel dynamic balancing regularly to ensure that the tires can run smoothly, avoid shaking, and improve the driving stability and safety of the vehicle. 
So, why don't repair shops take the initiative to do dynamic balancing?
Actually, it's not because the repair shop is lazy or forgetful. Rather, it is because balancing is a relatively complex and time-consuming technology that requires specialized equipment and personnel to carry out. In a general repair shop, it is difficult to dynamically balance each wheel after tire repair due to time, equipment and personnel constraints. Therefore, the repair shop usually advises the owner to do the dynamic balancing by himself after repairing the tire to ensure the safety of the vehicle.
So, does it mean that it doesn't matter if you don't do dynamic balancing after repairing the tire?
The answer, of course, is no. Although the normal driving of the vehicle will not be immediately affected by the dynamic balance after the tire is repaired, in the long run, it will cause damage to the tires and suspension system of the vehicle, and even affect the driving safety of the vehicle in serious cases. Therefore, it is very necessary to do dynamic balancing after tire repair.
If you don't do balancing, it may lead to the following problems:
1.Steering wheel shaking: The abnormal state of the wheels will reduce the handling sense of the car, and in serious cases, it will cause the steering wheel to shake.
2.Increased tire wear: Unbalanced mass can cause additional couplings on the tire, resulting in eccentric and wavy wear of the tire.
3.Increase tire driving resistance and increase fuel consumption: Unbalanced mass can also increase tire driving resistance, resulting in increased fuel consumption.
4.It has a certain impact on the service life of the wheel bearing: the unbalanced mass will have a certain impact on the wheel bearing, affecting its service life.
Therefore, it is recommended to regularly check and adjust the dynamic balance after the vehicle has traveled a certain mileage to ensure the balance of the tires and improve the driving stability and safety of the vehicle.
The difference between 20 yuan and 200 yuan tire repair is as follows:
1.Material: 20 yuan tire repair is used butyl rubber strip, and 200 yuan tire repair is used patch, mushroom nails and other materials, patches are suitable for the inside of the tire, mushroom nails are used to plug the tire wound.
2.Effect: The butyl rubber strip needs to clean the tire wound when repairing the tire, and use a special awl to plug the rubber strip into the wound, but due to the poor mutual adhesion of butyl rubber, it is necessary to add a tackifier to ensure that the adhesive strip will not fall off after being plugged in, but the addition of tackifier will cause the overall strength of butyl rubber to decrease, resulting in a slow air leak in the place where the tire is repaired. When using patches, mushroom nails and other materials to repair tires, you can clean the wound, use vulcanized glue to vulcanize different rubber at room temperature, and stick it to the wound on the inside of the tire, and the patch can gradually melt together with the original rubber of the tire, with higher strength.
Overall, the 20 yuan tire repair method is not as good as the 200 yuan tire repair method in terms of materials and effects. It is recommended that car owners should consider the safety and durability of tires and choose a more reliable way when choosing a tire repair method.
So, drivers, don't forget to do dynamic balancing after repairing the tire!If your repair shop doesn't offer this service, you can go to a professional car repair shop to do it yourself. Don't be stingy with that money, who will do it for you if you only give twenty?Remember, you can't afford to be sloppy about vehicle safety
