Why is there noise from the tires?

[LaLane]

Tire noise is caused by foreign objects such as stones. Below is an introduction about tires: 1. Introduction: Tires are circular elastic rubber products mounted on various vehicles or machinery for ground rolling. They are usually installed on metal rims to support the vehicle body, cushion external impacts, ensure contact with the road surface, and maintain driving performance. 2. Performance: Tires often operate under complex and demanding conditions, enduring various deformations, loads, forces, and temperature extremes during use. Therefore, they must possess high load-bearing capacity, traction performance, and cushioning ability. Additionally, they require high wear resistance, flexibility, and low rolling resistance with minimal heat generation. Half of the world's rubber consumption is used for tire production, highlighting their significant demand for rubber. 3. Specifications: Specifications indicate the geometric parameters and physical performance data of tires. Tire specifications are commonly represented by a set of numbers, where the first number denotes the tire section width and the second number represents the rim diameter, both measured in inches.
