How to solve the noise problem when driving Haval M6 on the highway?

[DeJonathan]

Haval M6 running on the highway has noise solutions as follows: Replace tires: Replace with softer tires or appropriately reduce tire pressure to reduce the noise generated by tire friction. Add sound insulation cotton: Adding sound insulation cotton is the most direct and effective method. Additionally, performing another round of sealing will also reduce tire noise. Door sound insulation: Use vibration damping panels or specialized vibration damping panels and sound-absorbing pads, along with door sealing strips, to comprehensively treat the fenders, car floor, and doors. Although the process is more troublesome, the sound insulation effect is better. Secure items: Pay attention to closing windows properly and securing items inside the car during normal driving, which also helps reduce noise.
