What causes the humming noise from car tires while driving?
2 Answers
The reasons for the humming noise from car tires while driving are: 1. Lack of lubrication or damage to the front wheel bearings; 2. Excessive gear clearance in the steering mechanism; 3. Sound from the turn signal returning to position; 4. Friction between plastic components; 5. Abnormal noise coming from the steering wheel; 6. Aging of the steering tie rod ball joint. The maintenance methods for car tires include: 1. Regularly check tire pressure, ensuring it is neither too high nor too low; 2. Frequently remove debris from the tire tread to avoid blowouts; 3. Inspect tire wear and replace them in a timely manner; 4. Perform four-wheel rotation to prevent excessive wear; 5. Avoid curbs and potholes to prevent sidewall ply breakage leading to tire bulges.
Tire humming is quite common, and I've experienced it myself before. It's most likely due to uneven tire wear, especially if the front wheels are misaligned, causing the inner or outer edges to drag, sounding like a subwoofer humming. Sometimes, if the tire tread gets a large stone stuck in it, it can also cause this, resulting in a mix of clicking and humming noises while driving. If it's a bearing issue, it's even more noticeable—the faster you go, the higher-pitched the noise becomes, like a whistle rising in pitch. Not doing a wheel balance after a tire repair can also cause this sound, making the wheel wobble as it spins. Why don't you first check if there are any stones stuck in the tire grooves? Then feel the tire surface for any wave-like wear—if it feels uneven, head to the tire shop right away.
