The bicycle tires are leaking again where they have been repaired

There are several possible reasons why a bicycle tire is leaking where it has been repaired:

1.Leaking air in the gap of the tire wire layer. This usually happens when the bicycle is used for a long time, or when the glue does not fully solidify during tire repair, causing the tire to leak in the wire layer due to the internal tire pressure.

2.Puncture results in air leakage. It may be that the tire wound was not completely sealed during the tire repair, or the tire was removed incorrectly, resulting in the tread being torn and causing an air leak.

3.Valve core leakage. The valve core is a key part of the control of tire inflation and deflation, and if the valve core is not tightened, tightly sealed, or cracked, it can lead to a tire leak.

4.Excessive clearance between tires and hubs. If the wheel hub is deformed or hit during use, resulting in deformation of the edge of the wheel, it will cause the gap between the tire and the hub to be too large, so that the tire often separates from the hub during rotation, resulting in air leakage.

5.The internal tire pressure is too high. If the pressure inside the tire is too high and exceeds the range that the tire can bear, it will cause bulges or cracks on the surface of the tire, which can cause air leakage.

6.Poor tire quality. Some poor quality tires may have problems such as cracking and wear during use, which will cause tire flats.

7.The use environment is harsh. If the bicycle is used in a harsh environment for a long time, such as often driving on rough roads, often exposed to the sun and rain, etc., it will also accelerate the wear and aging of tires, resulting in air leakage.

For the above reasons, you can try the following methods to solve the problem:

1.If it is due to air leakage in the gap in the steel wire layer, it is recommended to replace the tire, as this air leak is difficult to repair.

2.If the air leaks due to puncture, you can replace it with a new tire patch at a tire repair shop or by yourself. When replacing, make sure that the patch fits snugly and covers the entire wound to avoid secondary air leaks.

3.If it is due to a leak in the valve core, you can check the tightness and sealing performance of the valve core, and if you need to replace the valve core or replace the inner tube.

4.If the gap between the tire and the hub is too large, the hub needs to be removed for adjustment or replaced to reduce the gap between the tire and the hub.

5.If the internal tire pressure is too high, you need to use an air pressure gauge to adjust the tire pressure to the appropriate range.

6.If it is because the tire quality is poor or the use environment is harsh, it is recommended to replace the tire with better quality tires or improve the use environment.

When dealing with air leaks, it is recommended to check the air pressure and tire condition first, find out the specific cause of the air leak and deal with it accordingly. If you are unable to handle it on your own or are unsure how to deal with it, it is recommended to seek professional help.

You take out the inner tube, hit a basin of water, add gas, and then put it in the water, carefully check to see if there are other places leaking oil, or it may be that the valve is leaking, after the inspection, you also have to check whether there is any steel wire or nail on the inner wall of the outer tire! Check it to prevent it from being pricked twice...

It may be that the rubber is aging, and you can use a very sticky rubber to repair the car, and you can ride it at home for two days.

Causes and solutions for unexplained flat tire of bicycle rear tire:

1. The valve core is loose. You can use a valve core wrench to tighten the valve core firmly.

2. The rear tire is punctured by a small and sharp object. For example, small iron filings, wooden thorns, etc., because the hole is very small, it is not easy to be found, remove the inner tube, drive a small amount of gas into the basin, and you can see that there are small bubbles. Mark the bubbling place, wipe the water dry, and then polish the bubbling place with a tire repair file, and then apply glue to the tire repair piece.

That could be that core on the valve on the tire is broken.

When the wheels are removed and put into the water, there must be bubbles. Missed.

Take a look at the repair and squeeze it with water bubbles.

The inner tube of the bicycle can't find the air leak, so you can do it by filling the tires of the bicycle to full capacity. Turn the bike over and place the seat on the ground. Unscrew the air pump screws. Use a flat screwdriver to open the outer tire of the bicycle and pull the inner tube out of the outer tire.

Prepare a basin of tap water and press the inner tube of your bicycle into the prepared basin of tap water to look for air leaks. There are blisters in the water, which proves that there are small holes in the tires here.

Tube repair method:

Grind the small holes found with a file, and grind a circle according to the size of the inner tube patch, it doesn't matter if it's smaller, it must exceed the size of the inner tube patch.

Apply the special glue for tire repair in the place with small holes, and let it cool to let the benzene in the glue volatilize. Remove the plastic paper from the back of the inner tube patch, or find the same inner tube and use scissors to cut a piece of the same size as the one sharpened in the previous step. Stick the inner tube patch flat on the glued inner tube.

Press firmly and let it sit for a while until the glue is all dry. Put the mended place into the tap water basin again to see if there is still air leakage, if there is no blistering, it proves that the tire repair has been successful.

Then check the rest of the inner tube to make sure there are no other air leaks and then put the inner tube back into the outer tire. Install the tires again. Then turn the bike over and puff up the inner tube. In this way, the inner tube of the bicycle is repaired.

If the inner tube of the bicycle is leaking, you can not find the loophole, you can use a basin of water, and then put the inner tube into the water to pump up, so that you can obviously see that there is a leak, and you can determine the location of the loophole.

It's your inner tube that breaks.

The tires in the electric car are also very important, generally the electric car we buy back is an ordinary tire, and later for various reasons most of the owners will replace the tire with a vacuum, because the ordinary tire is easy to leak, once the tire is leaking, it can't run, you need to replace the tire, and the vacuum tire can generally be used for half a year, because the tire wall is thicker, the shock absorption and grip are better, if there is a hole, pull the inner tube out to make up for it, and inflate it.

In addition, the vacuum tire will not be deflated immediately after being punctured, because the inner surface pressure has a self-sealing ability to the breach after inflation, so you don't have to worry about the car on the road because there is no gas to push it, but the vacuum tire is about 10% more expensive than the ordinary tire, and many maintenance electric vehicles will not repair the tire, the vacuum tire can not be repaired like the ordinary tire, otherwise it will leak after about 1 month, many car owners said that as long as the hole is broken after the use of the vacuum tire, it is equal to waste, Because after that, there is an endless air leak and tire leakage, in fact, it is because of the problem with the tools used to repair the tire, and the glue used is ordinary glue.

In fact, the vacuum tire repair is very convenient, as long as you use the glue and tire repair skin will not appear not to run a month on the phenomenon of air leakage, if the vacuum tire is broken, we first use the tire repair small grinding wheel to smooth the hole, try to polish clean when grinding, check it after grinding evenly, see if there are any glue particles, be sure to polish evenly and smooth, when polishing should be careful not to touch the fan line inside, if you determine the grinding feelings, you need to use tire repair glue, tire repair glue needs to use the glue of the car, It is not possible to use tire repair glue on electric vehicles and bicycles or motorcycles, and then we can evenly apply the glue to the tire holes.

If you can't find the leakage point, install the inner tube, buy a bottle of self-replenishing fluid, pour it into the inner tube, and then slowly rotate the wheel, after a few turns, you can add air to the inner tube, not too much, and pinch it to feel a little hard.

After leaving it for 5-6 hours, pinch the tires again, and if you feel that the hardness of the tires is basically the same as when you first pumped up, you can ride with full breath.

If it's a bicycle and the inner tube of the bicycle is leaking, you can't find a loophole, you should fill the tire with this tire, and then hit a basin of water, put it in the water piece by piece, and see where the bubbles are bubbling, and where the bubbles are bubbling, that's where the air leaks.

Pump the inner tube a little, and then put it in a basin with water, and try it little by little, **bubbling, that is, there is a leak, and the air valve should also be tested.

If the inner tube of the bicycle is leaking, but you can't find the loophole, then it is recommended that you check whether there is a problem with the inner tube's air core. If there is an air leak, but the inner tube is not damaged, then it should be the problem of the air core.

If the inner tube is leaking and you can't find the leakage, it should be the slow air leakage caused by the excessive aging of the inner tube, and it is recommended that you replace it in time so as not to affect the normal use.

If the inner tube of the bicycle is leaking, if you can't find the loophole, you can take a basin of water, put the inner tube into the basin, a little bit, when there is a paint bubble, it means that this position is leaking.

Inflate the tire, then bring a basin of water, dip the tire next to each other in the water, the air leak will bubble, and you will find the loophole. That's what the mechanics do.

You can put the tires in the water and turn the tires gradually, and if there are air bubbles in the water, then you can find the hole.

Then go to the place where the bike was repaired and fix it. We can also remove the tires and put them in the water, so that the air leak will bubble and it will be easy to find the air leak. To sum up, look.

If you can't find it yourself, you can go to the master who specializes in repairing the bicycle to find the reason and then repair it, but you can't check any problem, then it may be that the tires are aging, and you can just replace it with a new one!

Pump the inner tube to the fullest, then use a basin to put some water, put the inner tube in the water again, try it, there will be blisters where there is a leak, so that it is easy to find the place where the inner tube is leaking.

If the inner tube of the bicycle is leaking and you can't find a loophole, you should try it with water, and the place with bubbles is leaky.

According to your description, if you confirm that the inner tube is not leaky, then you should check the quality of the valve core and the small eraser. Thank you for your understanding and support!

What should I do if I can't find a loophole if my bicycle inner tube is leaking? I don't think you can find a loophole, it must be the valve quasi-slow brake, you put it in the basin after you have enough gas, **bubbling is**air leakage, this is the best to find.

Remove the inner tube, fill it up, and put it in a basin full of water, and then there are bubbles and there is air leakage.

It's only 10 yuan to buy a slightly better inner tube, and if you can't make up for it, you can change it to an inner tube to ensure that it is easy to use.

Pump up the inner tube and put it in the water to find out where the air is leaking.

The bicycle tire was not punctured, but it slowly leaked because of du:zhi 1, valve core aging or dao

Dust accumulation. Change the valve core. Edition.

2. The inner tire of the bicycle has been in the tire for a long time, the aging is weak, and it is easy to leak in hot days, and it is not easy to find, so replace the inner tube.

3. The side and inner edge of the outer tire are damaged, which often makes the side of the tire rub against the road, and the side of the tire will wear out 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. Broken sides and inner edges of tires can cause tire leaks and a high risk of punctures.

1. It may be that there is a problem with the valve core, wipe it clean and replace it with a new one. 2. The inner tube has a slight 'sand hole' or a slight leak in the repaired place. Do it yourself to find the source of the leak

Tire repair or repair shop. 3. There is a glue solution that can be injected from the valve, and after pumping, you will go to the air leakage place to stay and solidify to complete the tire repair task. Put the glue.

Apply evenly to the bicycle valve core, taking care not to block the pores with glue. 4. Install the valve core to the bicycle immediately after application.

, so that slow gas can be prevented.

Why is the bicycle tire not broken?

The bicycle tire is not punctured but slowly leaks because:

1. The valve core in the tire valve is aging or dusty, it is recommended to replace it.

valve cores. 2. The inner tube of the bicycle is long, the aging sea is weak, and it is easy to leak in hot weather.

gas, not easy to find, it is recommended to replace the inner tube.

3. The side and inner edge of the outer tire are damaged, and the side of the tire is often rubbed against the road.

teeth, which will wear down the side of the tire over time; The inner edge of the tire.

Breakage is caused by a misoperation when removing and assembling the tires on the wheels.

As a result, this situation basically occurs after replacing new tires or repairing tires.

Install the tires on the link. Broken side and inner edge of the tire, will be.

Causing a leaky tire will also have a high risk of puncture.

4. There is a small trachoma in the tire, which causes the tire to leak slowly, which is okay.

Hit the tires to normal pressure, and then put the whole tire along with the wheels.

Put it in a large water tank and see if there are bubbles, if there are bubbles.

The bubbles indicate the presence of trachoma in this area.

Answer: Disassemble and check: If there is air leakage, make up for it, and check whether there are nails or other sharp objects in the outer tire after repairing. If the inner tube is aging or subsidized too much, the inner tube should be replaced. If the tire is badly worn or has scars or scars, it also needs to be replaced.
