What Causes Tire Noise?
2 Answers
Tire noise can be caused by: 1. Small stones stuck in the brake disc, causing friction noise during driving; 2. Abnormal wear of the tire bearing due to lack of lubricating oil; 3. The main material of the brake pads being heavy metal, which may have metal hard spots; 4. Deformation of the brake pad shield, causing it to rub against the rotating tire and produce noise. The functions of tires are: 1. To support the entire weight of the vehicle and bear the load of the car; 2. To transmit traction and braking torque, ensuring good adhesion between the wheels and the road surface to improve the vehicle's power, braking, and passability; 3. To prevent severe vibration and early damage to automotive components.
Tire noise may be related to air pressure issues. Both excessively high or low pressure can cause abnormal friction between the tire and road surface, resulting in humming or squeaking sounds. I've encountered this several times while driving, especially when the pressure was low – the tire would deform excessively, increasing noise and reducing grip. Another common cause is uneven tire wear, such as severe wear on front or rear tires, which can create harsh noises during driving and requires immediate wheel balancing. There might also be slight wheel hub deformation or foreign objects stuck in the tread. Remember to regularly check air pressure using a tire gauge and maintain the manufacturer's recommended value; inspect tire surfaces for abnormal wear or foreign objects; don't ignore noises as prolonged neglect can shorten tire lifespan and increase safety risks – it's advisable to visit a professional shop for diagnosis. Develop good habits by checking tire pressure every two months.
