- Wheel bearings: Worn wheel bearings can cause a humming noise that increases in pitch as the vehicle speed increases. The noise is typically louder when turning or braking.
- Brake pads: Worn brake pads can also cause a humming noise, especially when they are applied firmly. The noise is typically worse at low speeds.
- Tire tread: Uneven tire tread can cause a humming noise, especially when the tires are new or have been rotated recently. The noise is typically worse at higher speeds.
- Driveline: A faulty driveline, such as a worn universal joint or a bad axle, can also cause a humming noise. The noise is typically worse at higher speeds.
If you are experiencing a humming noise from your tires, it is important to have the vehicle inspected by a qualified mechanic to determine the cause and correct the problem. The exact fix will depend on the cause of the humming noise. The recommended maintenance includes regularly checking the wheel bearings, brake pads, tire tread, and driveline for wear and damage and servicing and replacing parts as needed.
