If the tire is repaired for a period of time, why does it leak

Hello, if the tire adhesive is not firmly pasted, it will leak, and if the wheel is often not used, a point of force will naturally consume a part of the gas from the periphery of the steel rim. [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello, exclude the words that have not been repaired, the tires will run out of air for a long time [There is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Check whether it is a tire leak, or a combination of tire and cylinder rim, you can put the air pressure high in the sink, see if there are bubbles, you will know which side is leaking. [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello! In two cases, one is that it is not repaired, and the other is that the valve core is leaking, please check it carefully [If there is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

We recommend: 1. In order to ensure safety, the valve must be replaced with a new one when installing tubeless tires. 2. After installing the tire, use a brush dipped in soapy water to brush the drawing on (a) the valve core (b) valve base (c) the tire flange at the joint of the tire lip to see if there will be air bubbles in order to check the air tightness of the rim.

3. Inflate in accordance with the regulations, and often.

Hello, this should be the tire is not repaired or the valve core is not good. [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

First of all, it is necessary to determine the size of the damage location, if it is an oblique wound must be nailed with mushrooms, if the hole is more than 1 cm, it is recommended to replace the new tire, mushroom nails are the best way to repair tires at present, but the cost is slightly more expensive.

The service life of tires is generally 2-3 years or about 6-100,000 kilometers. Tread depth at the lowest wear) should be replaced immediately. Tires that have exceeded their shelf life (especially spare tires, which have a life of about 3 years) have degraded their overall performance.

Because the inner liner of the tire is not repaired in time after the tire is nailed, or the inner liner is not completely repaired due to poor repair, the air runs out from the inside of the tire through the place where the inner liner is broken.

Small holes formed by gases or impurities in or on the surface of the casting. It is recommended that the tire has nails, bad repair, the inner liner rubber is cut, etc., and repairs it in the correct way, so that there will be no "sand hole", but it is recommended that the tire with "sand hole" should not be used continuously.

Insufficient tire pressure or excessive tire pressure can cause wear and tear and can be dangerous. Insufficient tire pressure will reduce the durability of the carcass; Increases the resistance of the tire movement, resulting in an increase in fuel consumption. Excessive tire pressure can reduce the grip of the tire, leading to irregular wear of the tire, especially those mounted on the drive shaft.

Old drivers should know how to judge the wear of tires, the easiest way is to check in time when the tire pattern wear is too much, the reference standard is, this standard is a family car, a car. Then the wear limit of trucks and passenger cars is higher. Therefore, we have to judge and check the tire pattern every once in a while.

Summary of car tire repair methods:

The external strip is easy to use, but the durability is average. When the tire is nailed and the nail hole is small, it is a good emergency option to repair the tire with an external rubber strip.

Although the hot repair only repairs the inner layer, because the hot repair film and the tire inner liner are integrated, the sealing effect is better and it is not easy to leak. However, the larger the nail hole, the less durable the hot patch tire will be. When the tire is nailed and the nail hole is small, the heat repair tire has a better effect and the durability is also good.

Although the cold repair is time-sensitive, it has high requirements for the tire repair master. When the test was repaired with cold repair, there was an air leak again, and the tire was reassembled for repair.

There are several tire repair methods for automobile tires, which can be divided into three types: cold repair (internal repair or paste repair), hot repair (commonly known as fire repair) and rubber strip method. The so-called cold repair is to remove the injured tire from the rim, clean the foreign matter at the wound, and paste a special tire repair rubber from the inner layer of the tire to complete the leak repair.

This method is similar to the tire repair method of bicycles, but it requires a special tire scraper and tire repair rubber to complete. It has the advantage that it can repair large wounds, but the disadvantage is that it is not durable enough; After a period of flooding or high-speed driving, air leaks may occur again. Hot repair (commonly known as fire supplement) is the most thorough tire repair measure.

Similarly, the tire should be removed from the rim and a special raw film sheet should be attached to the wound. The wound is then baked with a roaster until the raw film fits perfectly to the tire. The advantage of hot repair is that it is durable and basically will not leak repeatedly.

However, there are also disadvantages, that is, the technical requirements are high, once the heat control is not good, the tire may be scorched and deformed, so the damage to the tire will be greater. The rubber strip method is the simplest and most practical method for the majority of car owners, with low requirements for equipment (a set of tire repair tools and a small inflator pump is sufficient), and the professional and technical requirements for car owners are not high (as long as you dare to try yourself). Precautions; (1) It should be noted that there are many ways to repair a tire, but it is not a panacea.

If there is a wound of more than 6cm on the tire wall (i.e. the side of the tire), or if the tire crown is punctured by an object such as steel bar, it is generally best to replace the tire with a new one. (2) At present, there are still some "4S" stores in the market that do not provide tire repair services, and can only replace tires. Therefore, it is recommended to go to a professional tire shop to repair the tire.

3) If you choose an automatic tire repair agent, be sure to read the instruction manual carefully. General tire fillers should not be used on high-performance Z-class tires (high-calorie tires for sports cars) or motorcycle tires. It is best to wear protective glasses (goggles, glasses, sunglasses, etc.) when using.

4) For driving safety, please be sure to check the air pressure and appearance of the tires regularly

I didn't make it up, or there were small holes that were filled

And trachoma didn't find out.

Car tires can be used after repair, but whether they are as durable as before depends on the situation.

If it is pierced by a nail, if it is repaired well, the tire will not leak, and the quality is similar to that before the repair. When you run at high speed, you can run at the same speed as before, and you don't need to worry too much. But if the tire is cut by a knife or something, and the knife edge is not small.

At this time, it is necessary to pay attention to the tread, if the tread can also be repaired, if it is the sidewall, for safety reasons, it should be replaced with new tires.

Go to the repair shop to repair the tire first, if the air leak is relatively large, it naturally cannot be repaired, only replaced.

1. Tires are round elastic rubber products assembled on various vehicles or machinery and rolled on the ground. It is usually installed on metal rims, which can support the body, cushion external shocks, achieve contact with the road, and ensure the driving performance of the vehicle.

2. The tire is often used under complex and harsh conditions, and it bears various deformations, loads, forces and high and low temperatures when driving, so it must have high bearing performance, traction performance and cushioning performance.

3.At the same time, high abrasion and bending resistance, as well as low rolling resistance and heat generation are required. Half of the world's rubber consumption is used in tire production, which indicates the ability of tires to consume rubber.

2. Tires cannot be repaired under the following circumstances.

1. The tire side cannot be repaired.

2. The diameter of the crown through hole exceeds 6mm and cannot be repaired.

3. If the bead is damaged or deformed, the tread is deformed, the rubber is corroded by chemicals or the tire is damaged by lack of air extrusion.

4.Other anomalies cannot be repaired. For example, if you can see a lack of air on the tire (e.g. side rolling marks on the tire, blistering of the inner liner, etc.), it is not worth repairing because the tire structure may have been damaged and can no longer be used.

In addition, if the tires can no longer be used, some damage is not worth repairing.

If the tire is deflated, it is necessary to choose a qualified professional tire service shop for tire damage assessment and tire side repair to ensure the quality of repair. The side of the tire is seriously damaged, but we still decisively replace the tire, and safety is the most important thing when driving!

3. Tire use skills.

1. The car should not be too fierce when starting, whether it is an empty car or a heavy car, it should start slowly and steadily. Avoid tire resistance and reduce tread wear.

2. When driving on a good road surface, you should keep moving forward in a straight line, except for cars and avoiding obstacles, it is forbidden to swing left and right and make sharp turns to prevent the transverse cutting between the tire and the rim from damaging the tire.

If the tire is leaking, it is better to repair the tire first, if the tire is repaired many times and there is still a leak, then you can directly replace the tire.

You should choose to repair the tire, because it is more cost-effective, and the effect is also very good, and it will not be affected in any way while driving.

It is necessary to have a tire repair because it will not have any impact on the situation, and it can save money, and of course it is not necessary to go to a special place to repair the tire.

It should be replaced directly, because it is more reliable to replace it directly, and the driving in the future is very stable and there will be no danger.

The vacuum tire may also leak, it may not leak from the position of the repair, but it does not mean that there is no air leakage, the wheel hub and tire can not be completely sealed, and it will also leak slowly, so it needs to be checked, generally normal tires need about 2 months to check the tire pressure, if it is low, you need to make up the air.

Vacuum tires have high elasticity and wear resistance, and have good adhesion and heat dissipation performance, especially all-steel radial vacuum wheels, which are economical and durable.

Vacuum tires are increasingly used in bicycles, motorcycles, cars, buses, and trucks.

Vacuum tire leakage of electric vehicles can be repaired by internal repair method, sealant repair fluid and cold repair method.

Internal Supplemental Method

Polishing the inner surface near the tire nail hole, insert the mushroom nail into the nail hole, clamp the steel needle on the mushroom nail from the outside of the tire with pliers, pull out the handle of the mushroom nail until the crown of the mushroom nail is completely attached to the inner wall of the tire. Use rollers to make the strong rubber patches fit more tightly to the tires, and finally use a knife to cut off the excess shank of the mushroom nails.

Replenish sealant

Use automatic sealant repair, inject the sealant into the inside of the vacuum tire, flow to the breach and plug it, shake the bottle and can for about 1 minute before using the sealant, so that the liquid shakes evenly, and then the catheter mouth is stable with the tire valve, so as not to leak. Tear off the retaining ring on the top of the bottle and turn on the switch to work.

Cold patch method

The cold subsidy rubber is simple to operate but not durable enough, and it is easy to fall off after a long time for the sidewall, which is often deformed under pressure. However, this method benefits from its relatively low **, and the original damaged position has not been effectively protected, and the wound sticker will fall off after erosion such as rain, cement and sand.

Causes of vacuum tire flat in electric vehicles:

1. The vacuum tire is punctured by a small sharp object, which will not make the tire suddenly run out of air, but it is very likely to have a chronic air leak.

2. The adhesive strip that repairs the hole is aging and falling off.

3. The sealing of the tire edge and the steel rim is not good.

4. After the tire aging, it will cause the tire to bend, and there will be some trachoma thinner than a hair on the tire, and the tire is also very prone to chronic air leakage.

Vacuum tire leakage can be repaired by rubber strips, self-replenishment fluid, fire repair, etc.

1. Rubber strip tire repair

The rubber strip repairs the tire quickly, and this method is suitable for the vacuum tire to be pierced with a larger hole. But it has a disadvantage that it is quietly touched, pierced into a nail, so that it can not be repaired directly with the adhesive strip, the nail needs to be pulled out, and then, with a special vacuum tire glue gun, the hole is filed a little wider, and then the rubber strip is stuffed in. It caused more damage to the tires, because the hole was much bigger than before.

Therefore, this method is used less often.

2. Add self-rehydration fluid

Adding self-replenishment solution is currently the most used method, the first convenience of rough transportation, remove the valve core, pour glue into it, and then fill the vacuum tire with sufficient air. Secondly, in the future, if the tire is pierced into something relatively small, or pierced into a nail or something, you can make up for it yourself. relieved our worries.

Third, it lasts for a long time and works until the glue dries.

3. Fire supplement

The advantage of fire repair is that it is very durable, and there is basically no need to worry about repeated air leaks at the wound. However, it also has disadvantages, that is, the technical requirements during construction are high, because once the heat control during baking is not good, it is likely that the tires will be scorched, and serious deformation will occur.

Causes of tubeless leakage

1. Foreign objects penetrate the tire

A foreign body is the most common injury to a tire. Foreign objects that can easily penetrate tires include nails, screws, wires, glass shards, sharp stones, tiles, etc. Among these foreign objects, nails and screws are the most likely to puncture the tire, causing the tire to leak, and it can also be inserted into the tire damage, which may aggravate the damage to the tire if it is not cleaned in time.

2. The side and inner edge of the tire are damaged

In addition to the front of the tyre, which is easy to be "secretly calculated" by hard objects, the side and inner edge of the tire are also weak links. Some car owners have a poor sense of position, and often let the side of the tire rub against the road, which will wear out the side of the tire over time; The damage to the inner edge of the tire is caused by the operation error when removing and assembling the tire on the hub, which basically occurs in the process of installing the tire after replacing the new tire or repairing the tire.

3. The tire valve is damaged

If no abnormalities are found on the tires, then we can turn our attention to the valves. Family cars are basically equipped with tubeless, and the valves are mounted on the wheel hubs, and their materials are mostly rubber. After using the valve made of rubber for a period of time, under the influence of sun and rain and the air pressure in the tire, it will slowly age, the texture will gradually harden, and finally crack and leak.
