What Causes the Tapping Sound When Car Tires Are Rolling?
2 Answers
Car tires making a tapping sound may be due to excessive tire pressure. The sound could be from the body bouncing when the tire pressure is too high or the suspension is too stiff upon contact with the road surface; The sound could also result from the vehicle bumping over expansion joints on concrete roads; Or it might be caused by stones stuck in the tire tread or foreign objects adhering to the tire surface, producing noise when in contact with the ground. Concept: Car tires are one of the essential components of a vehicle, directly contacting the road surface and working together with the car suspension to mitigate the impacts experienced during driving. Performance: Ensuring good ride comfort and smooth driving; maintaining excellent adhesion between the wheels and the road surface; improving the car's traction, braking, and off-road capabilities; bearing the weight of the vehicle.
The tires make a tapping sound while driving, which I think is quite common. A few days ago, I also encountered this issue while driving and found that small stones or nails were stuck in the tire tread, causing noise as they hit the ground with each rotation. If the tire wears unevenly or the tread depth is insufficient, it can also lead to uneven contact sounds. Another possibility is an issue with the wheel hub, such as loose bolts or imbalance, which can easily cause such abnormal noises. When this happens, I immediately stop to inspect the tire surface. If something is stuck, I use tools to clean it out. Usually, avoiding potholes and driving too fast over gravel areas, along with regular tire checks, can effectively prevent trouble. If I can't handle it myself, taking it to a professional auto repair shop for inspection is the most hassle-free solution.
