What causes regular hissing noise from tires?

[OKhloe]

The reasons for regular hissing noise from tires are: 1. Brake discs mixed with small stones, causing friction noise during driving, or abnormal wear of tire bearings due to lack of lubrication or fatigue wear; 2. The main material of brake pads is heavy metal, which may have metal hard spots that can generate noise during driving; 3. Severe wear of brake pads, causing the metal backing plate of the brake pads to wear, resulting in abnormal noise during operation. Methods for car tire maintenance are: 1. Regularly clean stones from tire treads; 2. Avoid exposing tires to direct sunlight; 3. Frequently check tire pressure, which can be found on the inside of the car's fuel tank cap with normal pressure values, adjust accordingly; 4. Pay attention to suspension maintenance; 5. Regularly check front wheel alignment; 6. Choose road surfaces carefully while driving, avoiding objects that can puncture or scratch tires, and steer clear of chemical spills that may corrode tires.
