Why is there loud tire noise?

[VonSophie]

Tire noise is primarily caused by vibrations generated from the contact and friction between the tires and the road surface. The functions of tires include: 1. Supporting the entire weight of the vehicle, bearing the load of the car, and transmitting directional forces and moments; 2. Working together with the vehicle's suspension to mitigate impacts during driving and dampen resulting vibrations; 3. Protecting the car's components from severe vibrations and premature wear, adapting to the vehicle's high-speed performance and reducing driving noise; 4. Transmitting traction and braking torque, ensuring good adhesion between the wheels and the road surface, and improving the vehicle's power, braking, and passability.
