How to eliminate car tire noise? What causes car tire noise?

When a car is driving, there will be various noises, such as the sound of the engine, the sound of the wind and the sound of the tires. Because the tires are in direct friction with the ground, sometimes there will be a problem of loud noise, and even affect driving. So is there any way to solve the tire noise?

How to eliminate car tire noise

Replace the tires with relatively quiet ones

Different brands of tires have different technical characteristics. If the original car's tires have loud tire noise, you can consider replacing them with silent tires, such as Michelin, Continental, etc. These brands have softer tires, better comfort, and relatively less tire noise, but their wear resistance is very average. After all, you can't have your cake and eat it too!

Sound insulation for car chassis and wheel arches

When the original car leaves the factory, due to design and cost constraints, if the sound insulation of the chassis is relatively average, you can consider soundproofing it. There are many sound insulation materials now, and the solutions are similar. However, soundproofing the chassis requires disassembling the cab, which may be a pain if it is a new car. Soundproofing the wheel arches is very simple and can be easily done by DIY.

It is not recommended to do full car sound insulation

Soundproofing the entire vehicle is equivalent to performing surgery on the vehicle, dismantling it into pieces. Not only is it expensive, but the soundproofing effect is not as good as expected.

What causes car tire noise?

The tire noise of a car is generated by the friction between the tires, the ground and the air during driving. This is not only related to the structure and texture of the road surface, but also to the tire pattern, rubber quality and tire pressure. All major tire brands have their own silent tires. The tire pattern design and rubber quality are much better than ordinary tires, so the price is naturally much higher than ordinary tires, so they are generally only equipped with some high-end cars.

Tire noise is mainly related to the vehicle's own sound insulation. It can be improved from the noise source and the noise transmission path. If it really affects personal driving experience, it is recommended to replace it with Michelin tires, do a good job of sound insulation inside the tires, and try not to remove the door panels and interior trims for sound insulation.

What to do if the car sound insulation is not good

Tire noise

Replace Michelin tires; install at least six tanks of chassis armor; soundproof the chassis, especially the wheel suspension; replace thick floor mats throughout the vehicle. Four-pronged approach.

Wind noise

Wind noise will be transmitted from the ceiling and glass, etc. There is no way to eliminate it. It depends on the model and speed of the car. The only thing you can do is to remove the lining of the A-pillars on both sides and fill them with sound insulation cotton, but the effect is not very great.

Resonance

There are two types. One is that a certain component is loose, which can be checked and tightened.

The second reason is that during the vehicle manufacturing process, the rigidity is insufficient and the amount of anti-vibration plates laid is insufficient.
