What Are the Causes of Abnormal Tire Noises?

[SanBentley]

Here are the reasons for abnormal tire noises: 1. Nails or debris stuck in the tire: The noise occurs once per tire rotation, sounding like something is "tap-tap" hitting the ground, with the rhythm speeding up as the vehicle accelerates. If it's a stone, simply remove it. If it's a nail and the tire pressure is still adequate, you can drive directly to a repair shop for a tire patch. 2. Worn brake pads: Front brake pads usually have an electronic warning system, while rear ones often rely on mechanical wear indicators. When the brake pads are too thin, they produce a "screeching" metal-on-metal sound. The noise is faint when not braking but becomes louder and more piercing when braking. In this case, drive slowly to replace the brake pads. You can check the brake pad thickness through the wheel rim gaps—replace them if the thickness is less than 3mm. 3. Uneven tire tread: This noise sounds like the tire is constantly rolling over something, accompanied by steering wheel vibration and wobbling. It’s best to replace the tire in such cases. 4. Wheel bearing noise: This produces a "humming" sound that gets louder with speed. To check, lift the wheel and inspect as shown in the image (if available). If confirmed, visit a repair shop promptly to avoid axle or body damage. 5. Overinflated tires: Standard tire pressure is around 2.4bar (front and rear) when unloaded, and approximately 2.6bar (front) and 2.7bar (rear) when fully loaded. Check your vehicle’s manual for exact specifications, as they vary by model.
