Hello:
Regarding your question, it is necessary to check whether there is tire noise due to tire wear. Abnormal tire wear will lead to increased tire noise. Secondly, for normal tire noise, the door can be sealed, and installing the door sealing strip can appropriately reduce the noise when driving. I hope my answer is helpful to you.
Audi a4l has been driving for a year, and the tires are very noisy. What should I do?
Maybe it's gnawing at the tire. Check whether the tire is eccentric. It's best to go to 4S four-wheel alignment.
Audi tires are noisy and the engine is noisy. Is there any good solution?
For tire noise, the simplest and most effective method is to adjust the tire pressure to a moderate state. If the tire pressure is too high, the noise will increase. 1. If it is economically feasible, it is recommended to switch to a silent tire. This kind of tire has soft rubber and special pattern, so the tire noise is low. 2. Sound insulation: Shock absorption, sound insulation, sound absorption and buffering are the only way for tire noise to reach the engine room. The main transmission part includes: chassis, blades and wheel arc; The main materials used are damping glue, sound-absorbing cotton and special wheel arc lining. Because the sound insulation work is more complicated, it is recommended to drive the car to a professional maintenance point to replace the relevant materials. 3. Try to choose a flat road surface during driving, which can effectively reduce the friction between the tire and the ground, thus reducing the tire noise.
What if Audi a4 is noisy? In this era of more and more pursuit of environmental protection, many people will choose to stay away from noise and impetuousness. Then, as a "second home", many car owners will upgrade the sound insulation of their cars, because the sound insulation of cars is becoming more and more common in the contemporary era, and the products they choose are diverse and the prices are uneven. Considering the construction technology of the shop, it has become a headache for car owners.
As a representative of domestic high-end cars, Audi A4 has always been known for its luxurious atmosphere. Its comfortable driving environment and stable control system have always been popular. At present, all Audi cars on the market should pay attention to one problem, that is, the wind noise, tire noise, road noise and other noises of the original car are obvious. Noise not only affects the driving mood, but also complicates the sound quality of the original car. What I'm sharing with you today is the sound insulation scheme from Audi A4.
A4 Audi sound insulation refitting configuration:
Chassis sound insulation: CSH elastic band, SPL08 cotton, NB3 elastic material tail box sound insulation: CSH elastic band, SPL08 cotton, NB3 elastic material fender sound insulation: CSH elastic band, SPL08 cotton.
Russia imports StP sound insulation as a noise terminator, and all series products have their own powerful performance. Each material can cure diseases by targeting different noises and prescribing the right medicine. CSH bomb under StP series is a kind of multilayer damping material, including butyl rubber polymer layer and aluminum foil outer layer.
SPL08 cotton is a sound insulation material of double-sided adhesive tape, which consists of multiple layers of materials, including PPE, multi-layer foam, adhesive layer and cowhide lining paper layer. There are adhesive layers on both sides of the material, which has strong sound absorption and heat insulation functions.
The structure of the chassis is complicated, and there are many interior parts and decorative plates of the seat that need to be removed. Therefore, it is necessary to be very careful when disassembling the chassis part, and people with certain technical experience are needed to disassemble the chassis part, so as to ensure that the whole process is error-free. Every construction detail can fully reflect the professionalism and rigor of Goethe modified car, so you can rest assured when you choose Goethe!
The chassis adopts the first layer of sound insulation, which effectively attenuates sound and vibration and enhances the rigidity of sheet metal.
When road noise or engine noise intrudes, the chassis will generate * * * vibration. Therefore, Goethe's refitting technician used CSH bomb to carry out the first layer vibration and sound insulation treatment on the chassis, which can reduce the generation of low-frequency vibration and noise; Then SPL08 cotton wool is used for sound absorption treatment, which greatly enhances the sound insulation effect.
The first floor of the front foot was soundproofed by CSH bomb.
The second layer is treated with SPL08 cotton to absorb sound. Chassis sound insulation should be covered by 80% of the construction area of the main part (front pedal) and the secondary part.
Construction treatment of hub sound insulation.
The first baffle is a soundproof CSH bomb.
The second fender is soundproof SPL08 cotton. When running on the gravel road, the stones on the tires hit the inner lining of the car and made a loud noise. CSH bomb and SPL08 cotton enhance the sound insulation effect and reduce some noise. Enhance the sound insulation effect of the fender, reduce the heat transfer from the engine and exhaust pipe to the car, and effectively control the noise of the whole car.
The first layer of anti-vibration treatment was carried out on the tail box with CSH small bomb.
The second floor of tailstock is made of sound-proof SPL08 cotton. The sound insulation of trunk is to deal with the sound pressure of vibration of sheet metal parts and the exhaust sound introduced into trunk when driving at high speed. Using CSH bomb, SPL08 cotton and NB3 rebound material can greatly reduce the heat transfer from the engine and exhaust pipe to the car and improve the acoustic effect. After the sound insulation construction is completed, the accessories shall be repaired without damage. Experienced Goethe refitters can restore the accessories to their original state without any traces of sound insulation construction.
My Audi A4 tires are too noisy ~!
Maybe it's cold weather and hard tires.
Do the next four-wheel alignment, or replace the Michelin silent tire.
Can be replaced by Michelin ultra-quiet tires.
Hello!
Usually, tire noise can be solved by replacing a good tire.
According to our information, the tire size of your car may be 2 15/55R 16. If you need to buy tires, Michelin suggests:
Primy3st Hao Yue is an upscale and comfortable model. It is characterized by comfortable driving and low tire noise when driving. It is suitable for car owners who pay special attention to the braking performance of tires in both wet and dry conditions and want to maintain the excellent comfort of tires while taking into account certain handling.
See/home/products-services/pattern-detail/passenger car/primiti3st for details.
Because the tire manufacturer was not informed of the choice and change of the original tire size of the vehicle manufacturer, our information is incomplete. Even the same model may choose different specifications of tires in different years, so this information is for your reference only. The tires you buy must be the same size as the original car. If you need to change the tire size, you must go to a professional refit shop to upgrade the tire, or consult a car manufacturer.
You can also log in:/home/buying-guide/find-your-tyre to search for tire information of your car.
Reference: Michelin www.michelin.com.cn official website
It is recommended to check the following:
1. Tire pressure
2. Whether the tread is abnormally worn.
3. Whether there are stones or foreign objects on the tread.
In addition, choosing Michelin comfort mode tires, such as PRIMACY3ST Hao Yue, can also improve tire noise.
How to solve the noise of Audi a6l tire?
Audi a6l tires are noisy and can be changed! It should solve the problem.
Car owners can go to a quiet place for a test drive at night when there are not many vehicles, and try to loosen the oil repeatedly at about 80 yards. If the absolute sound comes from the front, that is another problem; If it rings on both sides, it is tire noise.
