The mountain bike has a flat tire and needs to be replaced! How to avoid punctures on mountain bikes

If your mountain bike has a flat tire, you really need to change your tires. Here are the steps to change your tires:

1.First, prop up the bike and make sure it is stable.

2.Have new tires and tubes ready, and spare tires and tubes are usually provided with the purchase of a bike.

3.Unloading the current tires usually requires the use of a tire removal tool to unscrew the tires from the hub.

4.Place the inner tube in the water and find out where the damage is.

5.Cut a small hole in the broken area to pull the inner tube out of the outer tire.

6.Pull the inner tube out of the hole and split the broken part.

7.Install a new inner tube, tuck the inner tube into the outer tube, and make the broken part of the inner tube coincide with the broken part of the outer tire.

8.Tuck the inner tube opening into the tire cushion and secure it to the outer tire.

9.Inflat, inflate the tires to the proper pressure, the pressure can be measured using a bicycle pressure gauge.

10.Finally, check that the tires are securely fastened to the hub and that the air pressure of the tires is normal.

I made up the flat tires in my car by myself, so you should understand all that. No one stipulates that the inner tire of the mountain bike should be replaced if it bursts, and it is normal to have a puncture, so learn the tire repair technique by yourself and buy a set of tire repair tools, which is very cheap. Carry tools on the road, make up for it at any time if it is broken, prepare an inner tube when riding a long distance, and replace it if you don't want to make it up, how simple it is.

If there are too many holes, change it, and generally buy the worst Jianda tires below 20.

Tire puncture, on the one hand, this situation is caused by the quality of the inner tube, and on the other hand, it is caused by improper use.

1.If you have a pump on the barometer, please hit it close to the air pressure number marked on the tires. If you don't have a barometer, feel it with your fingers.

Generally speaking, you have to pinch the outer tire with your fingers, and you can still pinch it, but it is very, very hard to pinch. The tires are stiff, and a lot of sharp stones, broken glass, etc., will bounce off when they hit it, and they can't get in. Greatly reduces the chance of getting pricked.

2.When stopping to rest, pay attention to check the outer tire to see if there is any broken glass, small iron pieces, stones and the like embedded in the outer tire, and clean it in advance. These things may not puncture for a while, but the speed and distance of the ride will cause them to go deeper and deeper until they puncture the inner tube.

3.Ride a bike to watch the road and avoid suspicious things on the road. In addition, walk as close to the middle of the road as possible, and generally have more glass and iron sheets on the side of the road.

One. Don't inflate too much, especially on hot days.

Two. The reason for the road surface is that a bicycle is not a tank, and not all roads can be passed.

Three. Keep it in a cool place as much as possible.

There are two ways: one is to install a puncture-proof tire mat, and the other is to use a vacuum tire.

The former is inexpensive, but it is not completely stab-proof, and it cannot prevent snake bites, and the tire cushion is more likely to burst after aging; The cost of the latter is relatively high, but it doesn't matter if it is pierced, it will never be bitten by a snake, and it has the advantages of obvious road feeling, reduced resistance, and enhanced control.

The choice is up to you.

Don't puff too much, just moderate it! Now there is a car tire that is solid.

The quality of the tires is poor.

I haven't been going to school for many years, and suddenly I saw that the decimeter is still a little cloudy Later, I remembered that a decimeter is 10 centimeters, which is a mountain bike that will not have a flat tire under normal circumstances, but if the speed is particularly fast, it is best to jump over the rabbit.

The total love of flat tires depends on the following factors.

1. The load is too heavy.

2. External reasons (poor road conditions or foreign bodies).

3. Inner tube quality.

4. The mat is of poor quality, or is not in the right position. Causes the inner tube to come into contact with the spoke holes of the rim, and the spoke holes cut the inner tube.

5. The inner tube installation is not standardized, and the inner tube has wrinkles.

6. The air pressure is too high.

7. The inside of the outer tire is uneven.

8. The inner tube does not match the rim or outer tire.

It's all right, it's just a matter of luck.

It's all 1 decimeter, it's strange if you don't have a flat tire, and you are lucky if you don't roll over!

Friends who have had mountain cycling experience usually have such an experience, that is, when the bicycle encounters some special sections, the tire will be ruptured due to some bumps on the road, and in this case, they usually feel very annoyed. Veteran cyclists usually prepare spare tires, tire repairs, inflators and other tire repair tools. In the case of a puncture on the bike, these tools can play a good role, so if the tire bursts, find a stable and safe place, turn the bicycle upside down and place it on the ground, then take out the tire repair tool, take out the inner tube and replace it with a spare tire.

Introduction to cycling tire repair tools: 1. Spare inner tube, puncture tire is the most common problem when going out to ride. So carry a tube with you that fits your car.

The spare tire takes up little space, is simple to use, and can be replaced in a short time to continue riding. Second, inflatable cylinder, tire repair tools In addition to spare tires, you also need a set of tire repair tools. You may ask, if you have a spare tire, wouldn't it be more than enough to bring a tire repair tool?

That's not true. Murphy's theorem reminds us that it is possible for a freshly changed inner tube to break again. In addition, bringing a tire repair tool can help others.

Why not? 3. Tire pry rod, and use tire pry rod when repairing tires. The tire lever can be inserted into the gap between the tire and the rim and pry the tire off.

Then repairing or replacing the inner tube is a piece of cake. In addition, the tire pry lever can be placed in the pocket of a cycling bag or jersey. You must not forget them.

Remember not to continue riding after a broken tire, otherwise not only will the inner tire be damaged, but it may even cause the outer tire to gradually deteriorate after being pressed against the potholes. Be sure to get out of the car first and then do the tire repair work. If you don't have a spare tire, you can borrow it from the riders around you.

How much do you weigh? If it is also 100 pounds, the two of them together will not press the tires.

Burst. If there is repeated air leakage, it is most likely that the outer tire has glass slag or small nails, etc., and it has not been cleaned when the tire is repaired for the first time. At the car shop, I just put on the inner tube and put it back in the outer tire. If you walk around, you will have a leaky inner tube.

It is recommended to remove the inner tube and outer tire, carefully repair the inner tube, carefully check the inner wall and outer wall of the outer tube to see if there are any small sharp objects, clean it and reinstall the inner and outer tube. It shouldn't be leaked again.

If there is still a leak, it means that the quality of the inner and outer tires is too poor, and it is recommended to replace them.
