What are the methods to reduce tire noise in cars?

Methods to reduce tire noise in cars include: 1. Switching to noise-reducing tires; 2. Performing sound insulation treatments on the vehicle, such as chassis armor, engine compartment insulation, and cabin insulation, all of which can help reduce tire noise. Tire noise is generated by the friction between the tires and the road surface when the vehicle is driving at high speeds, and its intensity depends on road and vehicle conditions—the worse the road conditions, the louder the tire noise. The functions of tires are: 1. Supporting the entire weight of the vehicle and bearing the load of the car; 2. Transmitting traction and braking torque to ensure the adhesion between the wheels and the road surface; 3. Reducing and absorbing vibrations and impacts during driving, preventing severe vibrations and premature damage to vehicle components; 4. Adapting to the high-speed performance of the vehicle and reducing driving noise, ensuring driving safety, handling stability, comfort, and energy efficiency.
After years of commuting by car, the excessive tire noise was affecting my mood. I tried switching to low-noise tires, opting for Michelin or Bridgestone's quiet series, which made a noticeable difference. Regularly checking tire wear is crucial; once the treads are worn flat, it's time for new ones. Maintaining proper tire pressure is also important, as both overinflation and underinflation increase noise. Additionally, soundproofing the doors with some sound-absorbing foam significantly reduces noise. When driving, avoid rough roads and stick to smooth highways whenever possible. These small adjustments make driving much more comfortable, and music in the car sounds clearer. Don't neglect tire maintenance—rotate them every six months to extend their lifespan.
As a car enthusiast, I've been tinkering with cars for a long time. To reduce tire noise, the key is choosing the right tire type - high-grip models usually have lower noise levels; try performance brands like Dunlop or Pirelli. For modifications, consider installing underbody armor or adding buffer spacers, but don't compromise handling. Adjust the pressure accurately, measuring when cold is most precise. Choose smoother road surfaces as uneven ones amplify noise. I've also checked tire balance and wheel alignment - get them corrected immediately if deviations are large, otherwise tire noise will keep increasing. Quiet tires are indeed more expensive but worth it, significantly improving the driving experience.
