* Worn tires: This is the most common cause of a humming sound from a tire. When tires wear down, they can develop a scalloped pattern that can cause them to hum.
* Misaligned tires: This can also cause a humming sound. Misaligned tires can cause the tires to wear unevenly, which can then lead to a humming sound.
* Damaged tires: This can also be a cause of a humming sound. When tires are damaged, such as if they've been cut or punctured, they can develop a humming sound.
* Wheel bearing problems: This can also be a cause of a humming sound. Wheel bearings are responsible for allowing the wheels to rotate smoothly. If the wheel bearings are damaged, they can cause the wheels to wobble, which can then lead to a humming sound.
Depending on the severity of the cause, a humming sound from a tire can range from a mild annoyance to a dangerous safety hazard. If you hear a humming sound from your Chevy's back tire, it's important to get it checked out by a qualified mechanic as soon as possible.
