What Causes Abnormal Noises from the Wheels?
1 Answers
Wheels can produce the following three types of abnormal noises: 1. Clicking sound: This occurs when the tire is punctured by a nail or has a small stone stuck in it. The noise happens once per wheel rotation, resembling something "clicking" or "tapping" against the ground, with the rhythm speeding up as the vehicle accelerates. If it's a stone, simply removing it will suffice. If it's a nail, and the tire pressure is still acceptable, you can drive directly to a repair shop to fix the puncture. 2. Groaning sound: This is caused by uneven tire tread, giving the sensation that the tire is constantly running over something, producing a "groaning" or "rumbling" noise, often accompanied by steering wheel vibration and a tendency to veer left or right. In such cases, it's best to replace the tire (or rim) and avoid driving with the issue. 3. Overinflated tire noise: This results in increased tire noise. For most passenger cars, the recommended tire pressure is around 2.4 bar when unloaded (both front and rear) and around 2.6 bar for the front and 2.7 bar for the rear when fully loaded. Each vehicle may differ, so refer to the owner's manual for exact values. Overinflated tires not only produce loud noise but also make the suspension feel stiffer, leading to a bumpy ride and lighter, less stable steering. In such cases, simply release some air to adjust the pressure to the standard value.
