What Are the Reasons for Loud Car Tire Noise?
2 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.
