The newly bought bicycle has a lot of tire noise, what s going on?

Any car has tire noise, and if you want to make it quiet, you can only change the outer tires, or not the slick tires.

Because this is the sound produced by the friction of the tires, only the friction of the contact surfaces.

Decrease, in order to reduce tire noise, that is, to replace with bald tires, but if there is sand on the road, then ride fast, pay attention to ride fast, because of various reasons to fall is a common thing, to know that there is a return to have a willingness.

Besides, isn't it very windy to have tire noise? My car tire noise is also very loud, especially after 20km h, but I don't know how your car's tire noise is, my car's tire noise is very good.

There are several reasons why a new bicycle tire is noisy:

1.High tire friction: New tires may cause high tire noise due to friction of rubber molecules, etc.

2.High tire pressure: If the tire pressure is too high, it can cause the tire to deform, increase friction, and thus increase tire noise.

3.Incorrect tire mounting: If the tires are not installed correctly, it can cause excessive tire noise.

4.Bicycle structural design problems: The structural design of the bicycle can also lead to excessive tire noise.

For these reasons, you can try to reduce tire noise by replacing new tires with low friction coefficients, adjusting tire pressure, reinstalling tires, or optimizing the structure of your bicycle. If none of the above methods can solve the problem, it is recommended to consult a professional for maintenance.

Normal phenomenon, tire noise, is an inevitable problem for all cars, drivers and passengers may feel big and small, especially when the surrounding noise is small, feel that the tire noise is extraordinarily large, abnormal tire noise is caused by abnormal tire wear, and the tire can not completely avoid abnormal wear.

Tire is one of the most important components of the car, its main functions are: to support the full weight of the vehicle, to bear the load of the car; Transmit the torque of traction and braking to ensure the adhesion between the wheels and the road surface; Reduce and absorb the vibration and impact force of the car when driving, prevent the auto parts from being subjected to severe vibration and early damage, adapt to the high-speed performance of the vehicle and reduce the noise during driving, and ensure the safety, handling stability, comfort and energy-saving economy of driving.

If the maintenance is complete, the tires should be reinflated. When the air is more fully inflated, the stiff tires running on the road may make the noise slightly louder. Another possibility is that updating the air filter, engine oil, and even tire inflation will make the engine work easier, which will naturally reduce the operating noise of the engine.

In this way, when you start running, the road noise and tire noise will become more clear and audible.

If it's not something wrong with your feelings, then please consider that the car dealer will do a balance correction on the left and right wheels, and if it still doesn't change, you need to do a 4-wheel alignment. Hope it helps.

The reason why the tires are noisy is very much:

1. It is the instantaneous release of the air squeezed by the tire and the road surface to produce noise.

2. It is the tire pattern block that rhythmically knocks on the ground to cause resonance and noise.

Therefore, there is a direct relationship between the noise level of the tire and the tread design. In addition, when the new tire is first installed, the tire pattern percussion resonance is large, and the noise will be very large.

The reason why the new tires are noisy is because the tread resonance of the new tires is large, which makes the tire noise large; It may also be that the new tires have a different aspect ratio than the old tires, which have a low aspect ratio and a large contact area with the ground, resulting in a lot of tire noise. It may also be because the new tires are too hard, resulting in high tire noise.

In addition, in fact, the relationship between tire pressure and tire noise is very close, and tire pressure affects the size of tire noise. If the tire pressure is too high, it will cause the tire to become stiffer, which will increase the tire noise. If the tire pressure is too low, it will also cause the contact area between the tire and the ground to become larger, the friction coefficient will become larger, and the drag will become larger, which will make the tire noise larger and more fuel-efficient.

Buzzing after a new tire change can also be done in an inappropriate way when changing a tire:

1. After the car is replaced with new tires, the technicians do not do dynamic balancing, resulting in uneven resistance and wear of each tire, and the phenomenon of "eating tires" appears.

2. The new tires are wider than the old tires, the contact area between the tires and the ground is larger, the friction coefficient increases, and the tire noise also increases. Because the tire noise is louder than ever, the driver feels an abnormal buzzing sound.

3. In the process of replacing new tires, the car may not do well in some places, resulting in bearing problems.

1.If the stem screws are not tight, there will be a bumpy road surface and abnormal knock sound. Detection method: When the car is stationary, press the handlebars left and right. Solution: Tighten the screws.

2.Abnormal noise at the connection between the seat post and the frame. Detection method: Press the saddle hard when the car is stationary. Solution: Pull out the tube and wipe the inner wall of the seat tube and frame connection and the frame and seat tube connection.

3.Abnormal foot pedaling sound when pedaling. Detection method: Try a different pedal. Solution: Replace the pedal or remove the pedal for maintenance.

4.There is an abnormal sound at the crankset of the foot when pedaling. Detection Method:

Use your hand to break the crankset horizontally to see if there is a gap, and whether the front derailleur has been inaccurate recently. Treatment: The square hole crankset can be tightened with hexagon socket screws. This is not the case with a single crankset.

The integrated crankset is over, and the cadence is fast, which will cause the car to resonate and shake, and make continuous abnormal noise. Treatment: Replace the left thigh and crankset seal. Tighten the screws.

I haven't seen any abnormal noises in the closed bottom bracket so far. I also hope that other riders will bring up the fault to share and solve.

5.Abnormal noise at the rim, detection method: when the speed reaches 30 kilometers per hour, if there is a continuous sound, it is likely that the spokes are loose, stop and check whether the spokes are loose. To deal with it, go to the car shop and adjust it with a circle adjuster.

6.Abnormal noise when the disc brake brakes. The brakes make a terrible sound without failing, and it is very willing to make the pieces of the pieces broken by small stones. . .

No, it's that the car is not soundproofed. You can drive to different road surfaces to experience, generally the wind noise is the same when the speed is fast, the tire noise is different, the road surface is smooth, the tire noise is very small.

This is caused by tire noise when driving at low speeds. If you drive at high speeds, the wind noise is also very high. Both factors have an impact.

Hello, this is possible, for noise, you can do the whole car sound insulation can effectively reduce the noise.

The speed was not adjusted well, so I went to the car shop to transfer the car.

A good kit is generally not easy to drop the chain as long as the gear is adjusted.

Solve tire noise:

Key points of noise reduction: In this regard, there are many ways to reduce tire noise, such as sound insulation, which reduces tire noise by blocking the transmission of tire noise to the cockpit. In addition to removing the front and rear seats and interior trim of the vehicle, the tires and fender lining were also removed, and sound insulation materials were applied to the four doors, door sides, above the wheel arc, the four fenders and the chassis.

After targeted sound insulation, tire noise will be reduced to varying degrees. First of all, the original sharp rustling sound of tire noise has become a relatively low brushing sound, the volume is smaller, and the different tire noise caused by different roughness of the road surface is obviously different, but it has also become smaller; The rumbling sound of the shock absorbers passing over the bumpy road is also short and dull; When driving on rough roads, the numbness in your feet due to the vibration of the chassis is also mild.

In addition to car sound insulation, you can also take the method of replacing comfort tires to reduce tire noise. The main factor that causes noise is the tread pattern, so comfort tires will be designed with quietness in mind.

To solve the problem of excessive tire noise, you must first know why it causes tire noise.

The causes of tire noise are generally as follows.

The design of the tire, in the process of driving the tire contact the ground, the impact force will produce vibration and irritating noise, so the noise of the potholes will be relatively large, which is also the reason, and many silent tires are very finely broken, which can disperse the friction of the tire to reduce the noise, if the tire pattern is sparse, the noise is naturally larger. Since it is a new car, the tire has not worn out and there is tire noise, which proves that the tire is congenitally insufficient, and the best way to solve the tire noise is to change the tire.

Tire gnawing, the so-called tire gnawing even if the wear of the wheel is abnormal, or unilateral wear or tire wear is serious, the tire noise will increase after the tire gnawing, at this time, only the four wheels of the wheel need to be positioned, and the tire noise will naturally decrease.

In addition to the above two ways to solve tire noise, you can also refer to some of these methods.

One of them: local noise reduction and sound insulation, since the tire noise is too loud, then add sound insulation and noise reduction materials for the four wheels to insulate the noise of the wheels.

Second: even if the foreign body in the wheel is cleaned, the wheel is easy to get stuck in the foreign body during driving, and the foreign body in the wheel is cleaned up in time to increase the contact area between the wheel and the ground, which can also be a better noise reduction.

It is also normal for a new car to have tire noise, and the resonance between the tread lines has not yet reached the level of harmony, but the car has been driven for a period of time, the wheels have been run in, and the tire noise is not so strong.

If the car is old enough or has a tire noise problem, the most direct way is to change the tires, what Pirelli, Michelin, Goodyear, these brands of tires are all good, tire noise or something is of course smaller.

Tire noise is the noise of air squeezing when a tire rolls over the road, as well as the noise of friction.

Tire noise is related to the tread material and pattern design of the tire, and it is also related to the quality of the road surface.

Asphalt pavement is usually much quieter than concrete pavement, but there is usually no way to choose which way to go. Therefore, it is completely unrealistic to deliberately choose a driving route in order to reduce tire noise.

In addition, using the method of reducing tire pressure to reduce tire noise will have some effect, but it is definitely not recommended! Improper tire pressure can lead to fuel consumption and safety issues, so it's also unrealistic.

There are three most realistic methods: one is to do vehicle sound insulation, especially the sound insulation of the wheel socket part has a more obvious effect on reducing noise. The second is to change the silent tires. The third is to get used to it, and to get used to it when you listen to it.

There are many causes of tire noise, the most common is that the tire tread is severely damaged, which leads to the vibration frequency of the tire being strengthened, so the vibration noise increases. But you're asking about a new car, so this reason can be ruled out.

If you want to make a new car tire noise, you can find the cause and solve it from the following aspects:

First, it may be that the tire pressure is too high. The average car owner knows that the tire pressure is too high and too low will have a certain impact on driving safety, too high tire pressure will produce tire noise, and too low tire pressure will lead to an increase in fuel consumption, so you have to observe whether the tire pressure of your new car is within the normal range, if it is too high, it may be the cause of tire noise, it is recommended that you go to the maintenance office to adjust the tire pressure.

Second, if it is not a tire pressure problem, if you are not short of money, I think you can change to a tire, which is a silent tire. Because in many cases, it is the tire resonance that causes the tire noise, and the strength of the resonance is determined by the tire pattern, and the silent tire is designed to reduce the resonance with an asymmetrical pattern, so as to achieve the purpose of reducing the tire noise.

Third, if you are a new car, you should still pay attention to the work of sound insulation. Generally, the sound of tire noise is too loud, and it is always the owner who is uncomfortable, so it is easier to solve the problem by doing a series of sound insulation work on the path that spreads to the car. The main parts of the propagation are the chassis, the fender board, and the wheel arc, which can be used to isolate the noise with shock-absorbing glue, sound-absorbing cotton and other materials.

Fourth, if you often use the car, it is best to adjust the position of the tires every 10,000 kilometers, because the position of the tires is not right will lead to abnormal wear, and it is best to clean it from time to time, which can also prevent abnormal wear of the tires.

Tire noise is a problem that every car has, but there is still a solution, and today the old driver will solve this tire noise problem for everyone.

First of all, we need to know why there is noise, and the transmission process of noise includes: sound source and vibration source, transmission path, and receiving device. However, the receiving device here is the human body, and the problem can only be solved by starting from the first and second links.

The easiest and most effective way to start from the root cause is to adjust the tire pressure to a moderate state, and if the tire pressure is too high, the noise will increase. Or switch to silent tires. The rubber of this tire is relatively soft and has a special pattern, so the tire noise is low.

Starting from the transfer process, sound insulation was applied to the four doors, the side of the door, the area above the wheel arc, the four fenders and the chassis. It is complicated to do sound insulation work, so it is recommended that the owner should go to a professional maintenance point to replace the relevant materials.

In general, using these two methods can reduce the annoyance caused by tire noise. However, if you want to isolate tire noise, you need to work harder and buy high-end cars.

Check the tires regularly, check the air pressure of the tires and the tire face every once in a while to ensure that there are no large stones or other debris stuck in the tire pattern. Clean out the debris in time and keep the tire pressure stable.

Regularly check whether the antifreeze, brake fluid, glass water, etc. are sufficient, antifreeze can ensure the normal driving of the vehicle in winter, not easy to freeze, brake fluid is an indispensable part of the brake system. Glass water is used to clean the glass, which must be sufficient to keep the vehicle running.
