How to Reduce Tire Noise?
2 Answers
To reduce tire noise, you can adjust the tire pressure to a moderate level, as excessive tire pressure can increase noise. Here is some relevant information: 1. Sound insulation: Good sound insulation in the vehicle is a primary method to reduce tire noise. It involves taking steps such as damping, sound insulation, sound absorption, and buffering along the path through which tire noise propagates into the cabin. The main propagation areas include the chassis, fenders, and wheel arches. 2. Wind noise: Wind noise occurs when the pressure of the oncoming wind exceeds the sealing resistance of the car doors during high-speed driving, entering the cabin. It is primarily generated and transmitted through the door sealing gaps and the overall thin steel panels. The faster the driving speed, the greater the wind noise.
As a seasoned driver with over a decade of experience, I find tire noise quite annoying, especially during long-distance driving. To reduce it, the key lies in tire maintenance and selection. First, switching to quiet tires is the most effective solution. These tires feature unique tread designs and internal soundproofing layers to minimize road noise transmission. Secondly, maintaining tire pressure at the recommended level is crucial, as both overinflation and underinflation increase tire noise—a simple pressure gauge for regular checks will do. Additionally, regular wheel alignment and balancing prevent uneven wear that amplifies noise. Installing basic soundproofing materials inside the car, like padding under the doors, can also block some noise. While driving, choosing smoother roads or reducing speed, particularly on concrete surfaces, makes a noticeable difference. I've tried these methods, and now my daily commute is much quieter and more pleasant.
