What Causes the Humming Sound After Replacing Old Tires?

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.

The reason for the humming noise might be improperly installed tires. Old tires themselves could have issues, such as uneven tread depth or severe localized wear, which can cause humming when driving. Additionally, if the tires were not aligned correctly during replacement or if the wheel hubs had dirt on them, noise could occur after installation. I've also noticed that incorrect tire pressure can cause similar problems—if it's too low, the tires can deform significantly. It's advisable to check if the tire pressure is appropriate, as the vehicle's manual usually specifies the recommended values. If the humming noise is accompanied by vibrations, it might be a balancing issue, and you should visit a shop for a quick inspection by a technician. Remember to regularly check your tire condition to avoid similar issues—safe driving is crucial.

The humming noise from old tires mainly occurs in three areas: defects in the tires themselves, such as significant deformation of old tires, uneven surface wear, causing humming during rotation. Improper installation, where the wheel hub isn't cleaned properly or screws aren't tightened during tire replacement, leading to noise at high speeds. Pressure issues, where tire pressure being too high or too low alters the stress points. The solution is simple: first, check and adjust the pressure to the standard value; if that doesn't work, just go to a professional shop for a balance check to save trouble.
