What are the methods to reduce vehicle tire noise?
2 Answers
Methods to reduce vehicle tire noise include: 1. Avoiding poor road surfaces; 2. Promptly removing small stones, metal pieces, and nails from the tires; 3. Slowing down to reduce vehicle vibration; 4. Adjusting tire pressure to an optimal level; 5. Installing sealing strips on the doors; 6. Applying sound insulation treatments to the chassis armor, engine compartment, and cabin. Methods for maintaining car tires include: 1. Regularly checking tire pressure; 2. Periodically inspecting tires for bulges, cracks, cuts, punctures, or abnormal wear; 3. Clearing foreign objects such as stones, metal pieces, and nails from the tire treads; 4. Performing four-wheel alignment or tire balancing.
I think the most fundamental way to reduce tire noise is to check and maintain proper tire pressure. Too low pressure causes the tires to deform faster, increasing rolling friction and naturally raising noise levels. Overinflation makes the tires too stiff, which also tends to generate noise. Personally, I make it a habit to check the pressure monthly and adjust it according to the recommended values on the door frame. Another useful trick is to rotate the tire positions regularly, doing it every 5,000 kilometers or so, which ensures more even wear and prevents uneven tire wear from causing extra noise. If the noise is too noticeable, simply switching to quiet-type tires can help. Many brands now offer dedicated quiet series with internal foam sound-absorbing materials, which are very effective. When driving, I try to choose smooth roads and avoid gravel paths, and slowing down over bumps can also reduce vibrations and noise. Cleaning the tire tread may seem minor, but it prevents small stones from getting stuck and making noise, making it worth doing regularly. Finally, if the budget allows, adding soundproofing padding to the wheel arches can significantly improve the overall quietness of the car, which is great for long-distance driving. Remember, noise reduction starts with the basics—it’s safe and hassle-free.
