What Causes the Humming Sound After Replacing Old Tires?
2 Answers
Car tire humming noise after replacement may be caused by friction between plastic components. Here are expanded details: Reasons for tire humming noise while driving include: 1. Insufficient lubrication or damage to front wheel bearings 2. Excessive gear clearance in steering gear assembly 3. Sound from turn signal return mechanism 4. Friction between plastic components 5. Abnormal noise from steering wheel 6. Aging of steering tie rod ball joints Tire maintenance methods include: 1. Regularly check tire pressure (avoid overinflation or underinflation) 2. Frequently remove debris from tread grooves to prevent blowouts 3. Monitor tire wear and replace when necessary 4. Perform tire rotation to prevent uneven wear 5. Avoid curbs and potholes to prevent sidewall ply damage and tire bulges
A humming noise after replacing old tires is quite common. I've encountered this situation before, and it's mostly due to issues with the tires themselves or improper installation. Old tires, after prolonged use, are prone to deformation or uneven wear, causing a humming sound when in contact with the road, much like irregular tread patterns rubbing against the surface. It could also be caused by insufficient or excessive tire pressure, as uneven tire inflation can increase noise. Another reason is improper balancing—if the balancing weights aren't adjusted correctly during tire replacement, the car will hum as soon as it moves. I recommend first checking if the tire pressure is within the normal range, such as using a tire pressure gauge. If that doesn't solve the issue, take it to a repair shop for tire balancing or a wheel alignment. Also, don't forget to inspect the tire sidewalls for any deformations or cracks—old tires age quickly, so safety concerns should be taken seriously.
