How to reduce tire noise? How can the noise of car tires be reduced?

I suggest you try it like this:

Way. 1. Adjust the tire pressure. The easiest and most effective way is to adjust the tire pressure to the most suitable state, because if the tire pressure is too high or too low, it will affect the noise level and more importantly, increase the risk of a puncture.

If the tire pressure is too high, it will greatly reduce the effect of tire shock absorption, and the noise will also increase; If the tire pressure is too low, the tire will increase the fuel consumption of the car when it comes into contact with the ground, and it will also increase the noise, especially when driving on a potholed road.

Way. 2. Open the skylight. This method is suitable for those cars with sunroofs, if you feel very noisy while driving, you may want to try opening the sunroof for ventilation.

However, it should be noted that the sunroof should not be opened too wide, because the higher it opens, the louder the noise. When you are in the car, turn on the inner circulation, the air in the car will be more circulated, and the passengers sitting in the car will not feel very closed.

Way. 3. Install sound insulation materials. It is recommended that if you feel that the noise is too loud, you can choose to install sound insulation materials in the place of the door or fender, such as replacing the sealing strip of the door, so as to reduce the amount of noise.

Way. 4. Replace silent tires. If there are conditions for car owners, they can simply change to silent tires.

In addition to reducing noise, silent tires are also very wear-resistant. It is recommended that when choosing silent tires, try to have tires with delicate textures, which are better.

The benefit of this: reduced tire noise

Precautions: In addition to paying attention to the problem of tire noise, do not ignore some small problems of tires, if you find that the tires are bulging, you must replace them in time, otherwise it is easy to have a puncture when driving. Therefore, we usually have to carry out regular maintenance of tires, and once we find small problems, we must deal with them in time, so as to ensure our driving safety and make the tires more durable.

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. Like the new technology launched by some manufacturers, the cross-sectional groove width of the whole circle of tire tread ** silent ribs can be kept fixed, so that the rigidity of the rubber flower block tends to be consistent when the tire rotates into the grounding surface, the vibration amplitude of the pattern block tends to be balanced, and the noise wave tends to be stable, thereby improving the noise and reducing the noise in the car by one decibel.

After replacing this comfort tyre, people will feel that the tire noise is significantly lower than before.

Glue a layer of black felt cloth or flannel cloth to the inner fender of the front wheels.

How to reduce tire noise.

Hello, car noise can be effectively reduced by means of vibration damping, noise reduction and sealing:

1. Sound insulation cotton reduces engine noise: The noise in the car is mainly composed of the noise of mechanical components such as the engine, the friction sound between the tire and the ground, the collision and friction sound caused by the car breaking through the air, and the internal noise caused by the vibration of the cockpit interior panel and other components.

Automotive experts said that the volume of engine sound increases with the increase of engine speed, and the sound of the engine can be further improved in addition to the control of the driver, and the car sound insulation project can be further improved.

For engine noise, it is best to paste a high-grade sound-absorbing foam acoustic material under the hood, which can not only absorb and consume a large amount of engine noise, but also suppress the vibration of the hood, block the heat from the engine, and protect the paint from high temperature damage.

2. The key points of sound insulation and noise reduction should be clear: road noise and tire noise are caused by the vibration and noise caused by the friction between the tire and the road surface, and at the same time, the tire noise generated by the asphalt pavement and the concrete pavement is very different. The best way to reduce vibration for road noise and tire noise is to improve tire noise and road noise by using vibration damping plates, sound-absorbing pads and door seals to fully insulate the fenders, floors and doors.

3. Strengthen sealing resistance and wind noise: wind noise is generated when the wind pressure exceeds the sealing resistance of the door and enters the car in the process of high-speed driving, and the faster the driving speed, the greater the wind noise.

In addition, the car body itself is like a box, and the sound itself has the property of refraction and overlap, when the sound enters the car, if there is no sound absorption and sound insulation material to absorb and block, the noise will continue to refract and overlap, forming a resonant sound. Strengthening the sealing resistance is the most direct and fundamental solution, and the door sealing strip can solve this problem very well.

Some noises are caused by the failure of the vehicle itself, such as abnormal tire pressure, irregular wear, suspension or chassis damage and abnormal engine noise. The sound insulation project of the system is mainly completed through three steps: vibration reduction, noise reduction and sealing.

Doors, trunks, chassis, hoods and roofs are the most likely places to generate air friction noise, so these areas are the focus of sound insulation and noise reduction. For engine noise, it is best to paste a high-grade sound-absorbing foam acoustic material under the hood, which can not only absorb and consume a large amount of engine noise, but also suppress the vibration of the hood and block the heat from the engine, and protect the paint surface from high temperature damage.

Hope it helps!

Usually the noise generated during the use of the car mainly comes from wind noise, tire noise and engine noise, and the wind noise is relatively easy to solve.

If the tire rubs against the ground, it will produce noise, and the rapid operation of the tire will also produce noise with the air in the place of the wheel cover. ’

Nowadays, there are also a lot of soundproofing materials on the market, which can make the other noises produced by the car very small, as long as the windows are closed, the mute effect is not bad.

Tire noise can be solved by regularly cleaning up stones or other debris inside the tire; Noisy tires can also be dealt with by maintaining the right tire pressure; If it is caused by uneven tire wear, it can be solved by doing wheel alignment. Moreover, in order to avoid uneven tire wear, four wheels should be rotated regularly to reduce tire noise; Of course, the driving speed and the smoothness of the road surface are also factors that affect tire noise.

1.From the perspective of tire design, reducing tire noise should be solved from two dimensions. First, from the perspective of rubber, the softer the material, the better the shock absorption of the tire, and the lower the noise.

2.The second is to solve it through different pattern designs. Nowadays, the vast majority of tire manufacturers have relatively mature products to reduce tire noise through various arrangements of patterns.

In order to stagger the resonance frequency between the veins and joints, a variable pitch design can be adopted, and the pattern groove design developed on the outer shoulder can be used to release air from the ravine, which can also reduce noise.

3.Although theoretically speaking, the finer the pattern, the better, but this is also related to the purity and density of the rubber. The angle of the groove of the pattern is small, and the noise will be small, such as:

The noise of the 90-degree pattern groove is much greater than that of 45 degrees. Alternatively, a closed type of trench can reduce the lateral flow of air on the countertop, so that there is less airflow movement and less noise.

The noise of car tires is related to a variety of factors, the main reason is the type of tire, that is, the material of the tire. Generally speaking, noisy tires are hard but have a long life, and noisy tires are soft and have a short life, so you can choose the right brand according to your actual needs.

Tire noise is mainly determined by tire material, tread pattern, and road surface condition.

Tires of the same type, the same material, the same structure and the same size are mainly solved by choosing a tire pattern suitable for the road surface.

Tire selection If you want to make the tires less noisy when they rotate, we can choose the tires that focus on the silent and comfortable series when we choose to buy tires, because the material of these tires is that kind of rubber, and there will be some advantages in the design of the tires, and the tire sound will be smaller when we drive.

If it's the car itself, there's no way, because some cars are not very noisy.

If you reduce it, you need to change to a set of tires with a quieter effect and softer rubber.

While driving, it is common to hear the noise generated by the tires. The quietness of the tires is an important indicator of the driving experience. When there is an abnormal noise in the car, it will bring people a very bad driving experience, and the reasons for tire noise are as follows:

1.The puncture is low, the contact area with the ground is large, the friction coefficient increases, and the tire noise is large.

2.It may be that the car has just changed its tires, and in the process of changing the tires, the car's four-wheel alignment is not good or there is a problem with the bearings.

3.The body stiffness is not enough, which causes friction or shaking between the door and the frame when the car is moving, which makes the body make abnormal noises.

4.Road noise, rough or uneven road surface, is also one of the causes of tire noise.

5.It is also possible that the sound insulation of the car is not good, so there is noise in the car.

There is currently no way to reduce tire noise by 90%, but there are ways to reduce tire noise to a certain extent.

1.Keep your tire pressure within the proper range, too high or too low tire pressure can cause tire noise.

2.When the car is soundproofed, materials such as shock-absorbing rubber, sound-absorbing cotton, and special arc lining for wheels can be used.

3.Swap out the tires and choose a quieter one.

4.Or try to choose to let the car drive on a flat road with good road conditions, which can reduce friction and reduce tire noise.

5.Regularly clean the stone in the pattern joints.

Of course, the noise of the tires is also related to the driving speed and the level of the road surface, the faster the driving speed, the louder the noise of the tires. However, tire noise is not as noticeable due to the high speed wind noise; The bumpier the road, the louder the tires make. In general, driving on city roads, the flat road plus the city itself is also very noisy, and the noise of the tires is not very loud.

However, the tire noise of the car does not have a great impact on driving, so don't panic when you find that you hear this sound, because this problem can be solved by itself.

You can buy low-noise tires, which are a technical modification of traditional tires, which are more wear-resistant and less slight-hearted during use. If you don't want to spend money on tires, you should maintain your tires in your daily life, such as refueling where you should be refueling, so as to reduce the sound of friction.

Adjust the air pressure of the tires, install sound insulation materials, etc. Because whether the tire pressure is too high or too low, the slag will increase the noise in the tire, and the installation of sound insulation materials can insulate the sound.

We can choose a wheel with less friction to accompany the stupid Li tire gear, and you can slow down when driving and don't brake suddenly. Lu Chi can adjust the tire pressure in time, but also open the sunroof, and can install some sound insulation materials.

You should choose a tire with good quality, and then you can also arrange a noise reduction modification, and you can also install fenders, so that you can reduce the noise of the tire.

First, look at the width of the tires and hubs to see if they are too wide, as wide tires are noisier due to wider bearing surfaces, and wider tires will squeeze out more air and push more "air masses" to create vibrations than those with narrower sizes.

For cars with a front engine, passengers sitting in the back will be more likely to perceive the rolling noise of the tires, because the rear of the body is relatively less affected by engine noise and wind noise, at this time, the tire noise will be highlighted, so when we judge the tire noise, most of them choose to sit in the back for screening.

Secondly, the tread design of the tire itself also plays a dominant role in tire noise, for example, the tread groove of a tire is 90 degrees, and the tread slope of the same car assembly is obviously designed with an acute angle, we can also easily compare the 90-degree groove pattern of the tire in terms of tire noise is more serious.

The wedge-ribbed tire is not stable enough when driving, because it will have a large amplitude of deformation during rotation, and when pushing and squeezing the air, it will produce air vibration, and when the vibration is strong, it will pass through the air medium to reach our ear drum.

Wide tires are noisy, and the friction surface increases, so the noise increases. The same is true for the design of the tread, and many high-performance tires generally use a larger "man" drainage pattern. The size of the tire directly determines the tire noise level, and the design of the tire pattern is also a major factor that cannot be ignored, because the grooves between the tread will squeeze and push the air to vibrate, and the air will also deform the tread, perhaps compression, or expansion.

1. For car owners with large tire noise, the simplest and most effective way is to adjust the tire pressure to a moderate state, and the noise will become louder if the tire pressure is too high.

2. If you have been tormented enough by tire noise, if the economy still allows, it is recommended that the owner change to silent tires. The rubber of this tire is relatively soft and has a special pattern, so the tire noise is low.

3. Do a good job of sound insulation. In the only way for tire noise to propagate to the cabin, do a good job of shock absorption, sound insulation, sound absorption, and buffering, and the main propagation parts include: chassis, fenders, and wheel arcs; The materials used mainly include shock-absorbing glue, sound-absorbing cotton, and special wheel arc lining.

Because of the complexity of sound insulation, it is recommended that the owner should go to a professional maintenance point for the replacement of relevant materials.

4. For car owners with large tire noise, try to choose a flat road surface while driving, which can effectively reduce the friction between the tire and the ground, thereby reducing tire noise.
