What is the reason for the rhythmic noise after changing tires?
2 Answers
The reasons for rhythmic noise after changing tires include: damage to the right front wheel shock absorber; deformation of the right front wheel hub; or damage to the drive shaft. Below is relevant information about car tires: 1. Functions of tires: Support the entire weight of the vehicle, bear the load of the car, and transmit forces and moments in other directions; transmit traction and braking torque to ensure good adhesion between the wheels and the road surface, thereby improving the car's power, braking, and passability; work together with the car suspension to cushion the impact during driving. 2. Tire lifespan: The lifespan of tires is related to many factors, such as climate, road conditions, driving habits, installation, maintenance, etc. According to international regulations, if the tires are used normally, they must be replaced when the tread depth wears down to 1.6 millimeters.
After I changed my tires and drove home last time, I immediately heard a rhythmic 'tapping' sound, like a drumbeat. The reasons could be: first, there might be an issue with the tire installation, such as unevenly tightened wheel bolts or improperly installed balancing weights, causing the wheel to wobble and collide eccentrically when rotating. Second, small stones or debris might be stuck in the treads of the new tires, making noise as they roll. Third, if the brake discs and wheel hubs don’t match, the friction sound would be rhythmic. Fourth, new tires might expose old suspension or bearing problems, making pre-existing issues more noticeable. I quickly pulled over to check and found a small screw embedded in the tread—removing it fixed the noise. I recommend drivers take a short test drive after changing tires to check for unusual sounds, as ignoring them could pose safety risks. Regularly inspecting tire installation details can prevent such incidents, because driving safety is more important than anything else.
