What Are the Reasons for Loud Car Tire Noise?
3 Answers
The reasons for loud car tire noise are: 1. Air noise caused by the airflow between tire tread gaps and the disturbance of air around the tires; 2. Vibration of the tire body and tread patterns; 3. Road noise due to uneven road surfaces. The solutions to reduce car tire noise include: 1. Choosing quiet tires with finer tread patterns; 2. Attaching a layer of cotton fabric to the inner protective panel of the tires; 3. Driving at a slower speed. The functions of tires are: 1. Supporting the entire weight of the vehicle, bearing the load of the car, and transmitting forces and moments in other directions; 2. Transmitting traction and braking torque to ensure good adhesion between the wheels and the road surface, thereby improving the car's power, braking, and off-road performance; 3. Working with the car suspension to cushion the impact during driving and dampen vibrations; 4. Protecting car components from severe vibrations and premature damage, adapting to the vehicle's high-speed performance, and reducing driving noise.
When driving, loud tire noise is often caused by various factors, mainly related to the tires themselves. As tires age and wear, the tread becomes shallower, the rubber hardens, and increased friction with the road surface naturally amplifies the noise. Low tire pressure causes excessive deformation, leading to instability and noise during rolling, while high pressure reduces elasticity and also results in louder noise. Additionally, if the suspension system malfunctions—such as worn shock absorbers or softened springs—vibrations transmitted to the tires can generate extra noise. Tread design is also crucial, with sport-oriented tires typically being noisier. Road conditions play a significant role too, as rough or slippery surfaces make the noise more noticeable. Regularly checking tire pressure and tread depth can help mitigate this issue, ensuring a quieter, more comfortable, and safer driving experience.
As a long-time car enthusiast, I find tire noise to be quite common, and I've encountered it several times in my experience. For example, after replacing old tires with new ones, the noise immediately reduced significantly, indicating that worn-out treads on aged tires are the main cause. Sometimes, unstable tire pressure leads to a humming sound at high speeds. There's a noticeable difference between tire brands—I've tried budget tires that were much noisier, while premium quiet tires performed much better. Road surfaces also play a role; they're silent on fresh asphalt but unbearably loud on gravel roads. Don't overlook suspension issues either, especially as the car ages and the shock absorbers wear out, causing tires to bounce and produce strange noises. Now, I make it a habit to check my tire condition every time I wash the car, and this routine has helped reduce problems significantly.
